Releases (360)

v2.1.227New

Claude Code 2.1.227

August 10, 2026

•Fixed feature flags being evaluated without the user's subscription tier when a session started with an expired login token, which could wrongly prompt Max plan users to enable usage credits for Fable
•Fixed every Bash command failing under claude-code-action with allowed_non_write_users on GitHub-hosted runners
•Fixed /tui bringing back a conversation that had been rewound to before its first message
•Improved slash-command menu: blue now marks only the selected row, matched characters are bolded instead of recolored, and emoji or accented names keep their glyphs
•Improved performance: fewer event-loop stalls on file-not-found suggestions and at-mention size checks

v2.1.226New

Claude Code 2.1.226

August 8, 2026

•Bug fixes and reliability improvements

v2.1.225New

Claude Code 2.1.225

August 7, 2026

•Added gateway spend-limit support to Claude Code's usage warning; the limit-reached message now names the cap, its reset time, and the operator's message (requires the gateway on 2.1.225)
•Added a workspace trust prompt to claude agents for untrusted directories, matching the behavior of claude
•Fixed a transient 401 replacing a long-lived CLAUDE_CODE_OAUTH_TOKEN with a stored login's short-lived token, breaking headless sessions until restart
•Fixed MCP OAuth servers on macOS intermittently failing with a burst of 401 errors, as if never authenticated, after a keychain read timed out
•Fixed auto mode counting a safety-filter refusal of its own permission check toward the consecutive-block limit; the action is still denied, but the model is now told to move on rather than retry
•Fixed cross-session messages staying parked without a notice or expiry in headless sessions and during startup
•Fixed conversation history breaking on Remote Control session resume after very large conversations were compacted
•Fixed hovering over a session in another project in the agents list changing the directory the next agent starts in
•Fixed claude self-hosted-runner registering and then failing every session when --base-dir cannot be created or written; it now exits at startup with a clear error
•Fixed Claude Code on the web sessions being misreported as stuck, re-sending a growing event backlog on every reconnect
•Improved Remote Control: photos attached from the Claude app are now shown to Claude directly instead of being read from disk with a separate tool call
•[VSCode] Fixed Focus view folding away the latest to-do list, a pending question's context, and settled answers; thinking-only folds show "Thought for Ns" and re-collapse when their turn completes
•SendMessage can now start a conversation with your Remote Control sessions on other machines by name (ListAgents shows them as name [ref]), instead of only replying after they message you first
•SendMessage: a Remote Control recipient you already confirmed is never swapped for a same-named session on this machine when its own list couldn't be checked

v2.1.224New

Claude Code 2.1.224

August 7, 2026

•Added self-hosted environments: claude self-hosted-runner turns your own machines or containers into a place Claude Code web, mobile, and desktop sessions can run, on Team and Enterprise plans
•Added archive plugin source: install plugins from a zip over HTTPS without git or npm, with optional SHA-256 pinning
•Added a cancel-and-confirm step when removing an unavailable paste changes a command's text
•Added ANTHROPIC_BEDROCK_REGION_PREFIX env var for Bedrock to prefer a specific cross-region inference profile over the AWS_REGION-derived one
•Added crossSessionInbound and dialogExpiry settings: cross-session messages sent to a session running with bypassed permissions are held for your approval, and messages to other sessions auto-deliver
•Added sandbox credential-masking options: extract and onExtractNoMatch for structured env values, decode: "jwt" with maskClaims for JWT-aware masking, and awsPairs/sigv4 for AWS SigV4 re-signing; these need network.tlsTerminate and are honored only from user, managed, or --settings settings
•Added cross-session SendMessage: Claude Code sessions can now message each other, on any of your machines, with ListAgents to discover them (macOS and Linux)
•Fixed long (>200 char) project paths resolving to another project's session directory under a shared sanitized prefix; session list, rename, fork, delete and /resume no longer cross projects
•Fixed SendMessage reporting "Message sent" when the write to a teammate's inbox had actually failed; failed deliveries are now reported as errors
•Fixed sandbox filesystem deny entries written with a trailing slash (e.g. denyRead: "~/.aws/") being silently bypassable on Linux and macOS
•Fixed sandbox violation details never appearing in Bash tool results; Claude now sees which file or network access was denied and why
•Fixed MCP tools that connect mid-turn being deferred for tool search without their names announced to the model
•Fixed plugin install records being silently corrupted when the same plugin is installed in multiple projects
•Fixed recalled or restored paste content occasionally attaching wrong data or silently losing text when the paste had aged out or placeholder numbers collided
•Fixed copy-on-select on Wayland sometimes not reaching the clipboard; the two selection writes no longer race
•Fixed the feedback survey's transcript share silently failing on long sessions; a failed share now shows an error instead of a success message
•Fixed Remote Control auto-start intermittently failing with "Remote credentials fetch failed" on a cold start with a stale login token
•Fixed Remote Control and SDK clients showing a blank "(no content)" message after /clear and other output-less commands
•Fixed a Remote Control session recreated after its server session expired uploading prior local conversation history into the new session
•Improved fullscreen mode to keep the full pre-compaction history in scrollback across repeated compactions, instead of only the most recent interval
•Improved Remote Control: attached web and mobile clients now see compaction progress and the post-compaction boundary instead of a silent pause; /clear resets now propagate to attached clients
•Improved Remote Control: connection failures now show a persistent failure indicator with details and a reconnect shortcut, instead of only an 8-second toast
•Removed the 200-subagent-per-session spawn cap; long-running sessions no longer refuse new agents (concurrency and depth limits still apply)
•Changed managed settings: the approval prompt no longer re-appears after re-login or org switching when the organization's settings are unchanged
•Changed the feedback-survey transcript share: with your consent it now also uploads the last request's model settings — the system prompt (which includes your CLAUDE.md instructions), tool definitions, and model parameters. Secrets are redacted as before, and these fields are dropped first if the share is too large
•Changed the Bash tool description to always note that command output is displayed to the model, not reliably to the user
•Changed recalled paste placeholder numbers to renumber when accepted into the input
•Changed Remote Control to archive the stale server session instead of leaving a dead one listed when a fresh session is minted after compaction or /resume
•[VSCode] Fixed the extension showing Remote Control as connected after the connection failed
•Fixed a session resume silently reconnecting Remote Control after the user turned it off (--resume, SDK hosts, and the VS Code extension)
•[VSCode] Fixed sessions not honoring remoteControlAtStartup when explicitly enabled

v2.1.223New

Claude Code 2.1.223

August 5, 2026

•Added owner wildcard entries ("owner/*") to the strictKnownMarketplaces and blockedMarketplaces managed settings for allowing or blocking all marketplace repos under a GitHub org
•Added a warning when workflow agents, forked skills, slash commands, or resumed background agents' requested subagent model is restricted and the parent model runs instead
•Added a /teleport hint in cloud sessions showing how to continue locally with claude --teleport <session id>
•Fixed a Bash permission bypass where a crafted command could hide parts of itself from permission checks
•Fixed permission prompts so commands padded with tabs or invisible Unicode can no longer hide part of the command from the approval dialog
•Fixed workflow scripts being able to use dynamic import() to run code outside the workflow sandbox
•Fixed a permission gap where an agent definition's bypassPermissions mode ignored the org bypass-permissions disable policy
•Fixed resuming a session after a mid-session /cd coming back empty
•Fixed gateway model discovery hiding Claude models registered under provider-prefixed IDs such as vertex_ai/claude-* or bedrock/anthropic.claude-*
•Fixed modelOverrides keys that aren't Anthropic model IDs being treated as the session's canonical model ID; unknown keys are now ignored as documented
•Fixed managed settings: server-delivered settings no longer disable the env block of a machine-local managed-settings.json or MDM profile; admin env now merges per key
•Fixed sandboxed commands failing to start on Linux when sandbox.filesystem.denyWrite covers the working directory
•Fixed forked background agents getting stuck "already resuming" for the rest of the session when rebuilding the fork's parent prompt failed during resume
•Fixed a resumed session failing every turn, or leaving the interactive app on an unresponsive error screen, when its history held a malformed diagnostics attachment
•Fixed a rare hang when parsing unusual git push output
•Changed CLAUDE_CODE_DISABLE_1M_CONTEXT to hold every Claude model with a native 1M window to 200K via auto-compaction, not just a fixed list; a startup warning now appears when auto-compaction isn't holding the session to 200K
•Changed auto-compact to keep sessions on unrecognized model IDs within the assumed context window instead of letting them grow past it; set CLAUDE_CODE_DISABLE_UNKNOWN_MODEL_WINDOW_ENFORCEMENT=1 to restore the previous behavior
•Changed /review to be an alias of /code-review, which reviews the current diff or a PR (/code-review <level> <pr#>); use /code-review ultra for a deep cloud review
•Changed /code-review with no effort level to reuse the level you typed last; type a level like /code-review high to change it

v2.1.222New

Claude Code 2.1.222

August 4, 2026

•Fixed worktree-isolated sessions and their subagents being able to run destructive git commands against the main checkout; isolation now applies to file edits and Bash in every session type
•Fixed PreToolUse auto-allow hooks bypassing tool restrictions in background agent tasks (summaries, compaction, renames)
•Fixed /usage-credits on Team and Enterprise showing "you've already sent a usage credit request" for members whose earlier request was dismissed, blocking them from sending a new one
•Fixed the startup connectivity check hanging and then failing behind an HTTPS proxy; it now uses the same proxy-aware transport as API requests and times out with a clear message
•Fixed "Connection closed mid-response" errors being reported on responses that had actually completed
•Fixed /usage overattributing usage to MCP servers: a server's share now reflects only the requests that actually consumed its tool results, instead of every turn after any call to it
•Fixed sessions not linking to pull requests created after the branch was pushed, including through the GitHub REST API
•Fixed org-restricted model: opus-style subagent and teammate family aliases dropping to the parent model instead of stepping down to the newest org-allowed model in the family
•Fixed stream idle timeout firing on custom ANTHROPIC_BASE_URL gateways despite server keep-alive pings arriving on the wire
•Fixed claude.ai connectors being falsely marked as needing authorization when the session token is invalid — they now show a /login hint instead
•Fixed tool errors not being displayed for tools no longer available locally, for example after an MCP server is removed
•Fixed SendMessage rejecting a long summary — it now truncates instead, so sends no longer fail on a character limit
•Fixed the spinner's effort label in a subagent's transcript view showing the session's effort level instead of the subagent's own effort: setting
•Fixed rare crashes when a file watcher hit a filesystem error or during file-watcher teardown
•Fixed screen readers re-reading the whole input line on every backspace in --ax-screen-reader mode — end-of-line deletions now echo just the deleted characters
•Fixed host model-selection keys not taking precedence over a stale on-disk managed-settings.json when CLAUDE_CODE_PROVIDER_MANAGED_BY_HOST is set
•Improved auto mode safety: messages sent to other agent sessions via SendMessage are now evaluated by the permission classifier before dispatch
•Improved the refusal when Claude tries to invoke a skill with disable-model-invocation: Claude is now told to ask you to run the skill instead of replicating its workflow
•Improved the /diff view, the Remote Control workspace diff, and file-edit diffs in Claude Code on the web sessions to use raw git blob content, ignoring workspace-configured diff drivers and textconv
•Changed Remote Control auto-start so repo-local settings (.claude/settings.json or .claude/settings.local.json) can no longer turn it on (they can still turn it off); enable it at user scope via /config
•Removed ultraplan feature

v2.1.221

Claude Code 2.1.221

August 3, 2026

•[VSCode] Added Focus view: a chat-menu toggle that hides tool activity behind an expandable per-turn summary with a live running-tool indicator, toggled with Ctrl+Alt+F or the "Claude Code: Toggle Focus view" command
•Added mode: "mask" for sandbox credential files on Linux and WSL — sandboxed commands read a sentinel copy (the whole file, or just the spans captured by an extract regex) while the sandbox proxy substitutes the real value on egress; on macOS file masking falls back to deny
•Added warnings to claude plugin validate when a marketplace or plugin name would be rejected by Claude Desktop's managed marketplace sync
•Added a prompt-audit subcommand to the claude-api skill for auditing prompts and tool descriptions for patterns written for older models
•Fixed a Bash tool permission-check bypass where zsh could execute hidden commands in [[ ]] regex conditionals; affected commands now prompt for permission
•Fixed PowerShell permission checks mishandling paths containing quote characters on Windows; such paths now prompt for approval
•Fixed the thinking toggle having no effect for the rest of a session that started with thinking off; disabling an MCP server mid-connect no longer silently reverts
•Fixed MCP servers from --mcp-config not being connected before the first turn in print mode (-p), which made the model emit tool calls as literal text
•Fixed @-mentioned files being silently dropped when pressing Esc to retract a prompt and resubmitting it
•Fixed a crash when preparing API requests for SDK MCP tools named after built-in object properties such as constructor
•Fixed WebSearch failing with a 400 error at effort xhigh/max when thinking is disabled
•Fixed sandboxed large uploads failing with TLS errors through the sandbox proxy
•Fixed Team and Enterprise spend-limit message incorrectly blaming the org's monthly limit instead of your individual spend limit
•Fixed Bedrock authentication with AWS SSO named profiles failing in desktop-managed sessions on Windows machines that set a stray HOME environment variable
•Fixed CLAUDE_CODE_RESUME_INTERRUPTED_TURN=0 not disabling interrupted-turn auto-resume; falsy values are now honored
•Fixed a rare wake-from-sleep race where two Claude Code processes could both refresh the same MCP connector or WIF OAuth token at once, forcing re-authentication
•Fixed renaming a session from Claude Code Desktop or claude.ai not updating the CLI's session name; session names from every rename surface are now sanitized
•Fixed plugin- and org-delivered skills named after terminal-only built-ins (e.g. /help, /feedback) being un-invocable in non-interactive sessions
•Fixed the "Plugins changed" notification lingering after plugins were reloaded instead of clearing
•Fixed Vim mode: the yank register now survives dialogs, history search, and the transcript view instead of being silently emptied
•Fixed Vim mode: undoing back to an empty prompt now arms the "press ← again" confirm before returning to the agent view
•Improved tool search on Google Vertex AI: re-enabled for Claude 4.5-generation and newer models
•Improved auto mode: permission checks for parallel tool calls are now cache-efficient, and switching modes while a check is pending reliably prompts instead of applying the stale result
•Reduced prompt-cache costs for auto-mode permission checks by reusing the cached conversation prefix across decisions
•Improved Stats panel to count cache tokens in its token totals, with a breakdown by input, output, cache read, and cache write
•Improved /ultrareview error messages when a repo shares no history with its base: a checkout with no branches is now refused up front with advice to create one, and refusal hints no longer suggest git fetch --unshallow on clones that are already complete
•Improved Windows startup: process creation times are now read via a native kernel32 call instead of spawning PowerShell, so endpoint security tools that gate powershell.exe no longer prompt
•Changed background sessions to commit and push to preserve work, open a draft PR only when the task calls for one, follow your CLAUDE.md git instructions, and always end by reporting where the work lives
•Changed /plugin install to refresh a stale marketplace catalog and retry before reporting a plugin not found
•Changed plugins installed from /plugin to activate immediately when safe, instead of always requiring /reload-plugins
•Changed plugins to accept "." as a skills path, and the root-level SKILL.md validation error now suggests using the plugin root
•Changed /status to show the session kind: interactive, or a background job that is attached or unattended
•Changed emoji autocomplete to accept common alternate shortcodes like :thumbsup:, :thumbsdown:, and :love:
•Changed sessions forked with /fork to create a new worktree of their own instead of working in the original session's checkout
•Changed Claude in Chrome to close the browser tabs it opens once it no longer needs them
•Changed fast mode to report on the stream when usage credits run out mid-session, instead of failing silently
•Changed Monitor: a watch that exits without producing any output now says so instead of reporting "stream ended"
•Changed the Gateway model field validation: non-string values are rejected with a 400 instead of being forwarded
•Removed the repeated "Permission mode changed while the auto-mode classifier call was queued" notice from approval prompts

v2.1.220

Claude Code 2.1.220

July 24, 2026

•Bug fixes and reliability improvements

v2.1.219

Claude Code 2.1.219

July 24, 2026

•Added Claude Opus 5 (claude-opus-5), now the default Opus model — 1M context, fast mode at $10/$50 per Mtok
•Added sandbox.network.strictAllowlist setting to deny non-allowlisted hosts for sandboxed commands without prompting
•Added DirectoryAdded hook that fires after /add-dir or the SDK register_repo_root control request registers a new working directory mid-session
•Added mcp_server_errors to the headless stream-json init event, listing --mcp-config entries skipped by config validation; terminal runs print a startup warning
•Added the workflowSizeGuideline settings key so the advisory Dynamic workflow size guideline can be set from any settings file; the /config row is hidden while one does
•Added nested subagent forwarding in stream-json: subagents spawned at depth-2+ now appear when --forward-subagent-text is set, keyed by their spawning Agent tool_use id
•Fixed claude -p text output dropping the answer already produced when a turn dies on a mid-stream API error
•Added HTTP status and error text to claude mcp list and /mcp when a server fails to connect, and a warning for MCP config values with hidden leading or trailing whitespace
•Fixed the Fable model row showing "Requires usage credits" for plans that include it, when a stale cache had baked the label in
•Fixed the /model picker showing the merged Opus row as plain "Opus" instead of "Opus (1M context)"
•Fixed copy-on-select inside GNU screen printing base64 into the terminal instead of copying the selection
•Fixed Remote Control clients keeping a stale fast-mode status after a model switch, reconnect, or failed org check
•Fixed CLAUDE_CODE_GIT_BASH_PATH on Windows exiting or being used as bash when the path isn't a bash/sh binary; it's now ignored with a warning
•Fixed Vim mode: pressing ← on an empty prompt now returns to the agent view from NORMAL mode, not just INSERT
•Fixed screen-reader mode rewriting the entire input line on every keystroke instead of echoing only the typed character
•Improved the "Remote Control is only available via api.anthropic.com" error to name the specific setting that caused it
•Improved claude --teleport to show which repo your current checkout points at when it doesn't match the session's repo
•Changed dynamic workflows to default to a medium size guideline (aim for fewer than 15 agents); pick another size or unrestricted with Dynamic workflow size in /config
•Changed managed MCP allowlist/denylist ${VAR} entries to resolve from the startup environment and managed-settings env instead of settings-file env
•Changed the /model picker to highlight only the newest model's name, so the highlight marks the new release rather than an arbitrary subset of the list
•Added the current default workflow size to the running-workflow status line, with a pointer to /config for changing it
•Removed Opus 4.7 from fast mode; /fast now applies to Opus 5 and Opus 4.8
•Updated the claude-api skill to default to Claude Opus 5, with a migration path from Opus 4.8
•Subagents can now spawn nested subagents up to depth 3 by default (was 1); set CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH=1 to disable nesting

v2.1.218

Claude Code 2.1.218

July 22, 2026

•Changed /code-review to run as a background subagent, so review work no longer fills your conversation and keeps stacked slash commands as its review target
•Added screen-reader announcements of deleted text for word and line deletions (Option+Delete, Ctrl+W, Cmd+Backspace, Ctrl+U, Ctrl+K) in --ax-screen-reader mode
•Fixed Windows paths with \u-prefixed segments (like C:\Users\unicorn) being corrupted into CJK characters in tool inputs, which made those files inaccessible
•Fixed the left arrow key discarding the conversation with no undo: presses right after editing now ask to confirm, and Esc in the agent view returns to the conversation it backgrounded
•Fixed multi-line paste collapsing into one line with j in place of newlines in terminals that encode pasted newlines as Ctrl+J
•Fixed /context reporting stale pre-compact token usage after compacting from the message picker
•Fixed /ultrareview failing on descriptive arguments like "review my auth changes" — they now run a review of your current branch with the text applied as a note to the findings
•Fixed /code-review ultra silently running a local review in non-interactive sessions — it now launches the cloud review
•Fixed gateway spend metering to price Bedrock application-inference-profile ARNs and other config-mapped upstream model IDs at the configured model's rates
•Fixed mojibake when a long IDE selection was truncated mid-emoji, and a case where a tool executor error could be silently dropped
•Fixed an engine teardown race that could start and abandon a phantom turn, and made input pushed after close consistently rejected
•Fixed spurious "[Request interrupted by user]" messages after interrupted tool calls, and an unpaired tool_use block left in the transcript when a tool aborted mid-response
•Fixed VoiceOver reading "new line" instead of echoing the typed space at the end of the input in --ax-screen-reader mode
•Fixed plugin and settings panels not moving the terminal cursor to the focused row, so screen readers and magnifiers can follow arrow-key navigation
•Fixed crashes (maximum call stack exceeded) when a deeply nested watched directory tree was deleted or moved, and when rendering deeply nested UI trees
•Fixed pull request events occasionally being lost when a session exited immediately after creating or linking a PR
•Fixed the Bedrock setup wizard failing profile verification for assume-role profiles in partitioned AWS regions and on proxy-only networks
•Fixed rare negative or incorrect turn duration measurements after a system clock adjustment by timing turns with a monotonic clock
•Fixed the "N MCP servers need authentication" startup notice over-counting claude.ai connectors that aren't connected in claude.ai
•Fixed prompt history entries being dropped or duplicated when history writes raced or failed
•Fixed a retry loop that re-sent identical doomed requests after a context-overflow error with a large thinking budget; Ctrl+B backgrounding now applies the same background-shell caps as other paths
•Fixed agent frontmatter hooks running from untrusted folders: hooks now require the agent file's own folder to have accepted workspace trust
•Fixed fork-session lineage being lost after compaction in headless and SDK sessions
•Fixed a resumed session failing every turn, or crashing on resume, when its history held a malformed delta attachment
•Improved /ultrareview error feedback so Claude can correct an invalid argument instead of retrying it unchanged
•Improved auto mode: the dangerous-rm, background-&, and suspicious-Windows-path checks no longer open permission dialogs; the auto-mode classifier adjudicates them instead
•Improved sandbox command restrictions for IDE interactions
•Improved trust dialogs to name the repository root the grant covers
•Changed /deep-research to start only when invoked manually; Claude no longer launches it on its own
•Changed plan mode with auto to no longer prompt for Bash commands the static analyzer can't prove read-only; the auto-mode classifier judges them instead
•Added an announcement when fast mode changes as a result of switching models via /config model=<x> or Remote Control
•Changed server-managed settings so benign feature and cost toggles no longer trigger the settings-approval prompt
•Changed agent markdown files to reject agent names containing :, which is reserved for plugin namespacing
•Changed skills with context: fork to run in the background by default; opt out per skill with background: false
•Added yes/no/on/off/1/0 (case-insensitive) as accepted values for skill and plugin frontmatter booleans, alongside true/false
•Fixed remote sessions continuing to send heartbeats after their worker was replaced, which left long-lived desktop and IDE processes retrying a rejected request every few seconds forever

v2.1.217

Claude Code 2.1.217

July 21, 2026

•Added emoji shortcode autocomplete in the prompt input: type :heart: to insert ❤️, or :hea for suggestions — disable with the emojiCompletionEnabled setting
•Added warnings when transcript writes are failing (e.g. disk full) or when session saving is off due to an inherited environment variable, instead of losing transcripts silently
•Fixed a memory leak where truncated MCP tool outputs kept the full untruncated result in memory for the rest of the session
•Fixed Windows auto-update failures that could leave claude.exe missing; failed updates now restore the preserved executable automatically
•Fixed background session isolation not canonicalizing symlinked working directories, which could let sessions escape their workspace folder
•Fixed auto-compact never triggering for Claude Opus 4.8 on Bedrock and /compact failing once over the limit
•Fixed corporate mTLS, TLS-verify, OAuth scope, and proxy settings being ignored in Claude Desktop sessions
•Fixed screen reader mode's startup announcement being cut off by the first prompt render, and the thinking status row re-rendering every few seconds to update elapsed time and token counts
•Fixed managed settings that set OTEL_EXPORTER_OTLP_ENDPOINT not governing all signals — lower-scope signal-specific overrides no longer redirect telemetry away from the managed endpoint
•Fixed --resume/--continue and /resume failing with a TypeError when a transcript has a malformed attachment entry
•Fixed Remote Control sessions not showing a pending permission prompt or dialog to viewers that connected after it appeared
•Fixed background shells sometimes becoming impossible to stop after a session is sent to the background (/background or ←) or when the session exits on a heavily loaded machine, most visible on Windows
•Fixed a CLAUDE.md or SKILL.md paths frontmatter value with many brace groups OOM-killing or stalling the CLI at startup — brace expansion is now budget-bounded
•Fixed the transcript preview sitting flush against the input area when attaching to a starting background session; it now leaves the same one-line gap as the live layout, so the transcript no longer shifts when the session takes over
•Improved footer PR badge links to be clickable hyperlinks even when terminal support can't be detected (e.g. over ssh/tmux); set FORCE_HYPERLINK=0 to opt out
•Changed the login-expiry warning to appear 3 days before expiry instead of 5
•Capped the frontend-design plugin suggestion tip at 3 lifetime impressions instead of repeating indefinitely
•Added a cap on concurrently-running subagents (default 20, override with CLAUDE_CODE_MAX_CONCURRENT_SUBAGENTS) so one message can't fan out unbounded background agents
•Changed subagents to no longer spawn nested subagents by default; set CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH to allow deeper nesting
•Fixed --max-budget-usd not stopping background subagents: once the cap is reached, new spawns are denied and running background agents are halted

v2.1.216

Claude Code 2.1.216

July 20, 2026

•Added sandbox.filesystem.disabled setting to skip filesystem isolation while keeping network egress control
•Fixed a slowdown in long sessions where message normalization cost grew quadratically with the number of turns, causing multi-second stalls and slow resumes
•Fixed auto mode denying commands with "HTTP 401" classifier errors after the OAuth token expired or rotated mid-session
•Fixed AskUserQuestion telling Claude to continue even when your answer asked it to wait or explain first — free-text answers now get neutral wording
•Fixed Claude Code on the web re-asking the same question and dropping your answer after the session sat idle for a few minutes
•Fixed @-mentions silently attaching nothing after file-modifying hooks, vim dot-repeat of c-operators and paste, statusline running twice on resume, and resume-picker hangs on failure
•Fixed resumed background agent sessions reverting to the default agent: the agent's prompt and tool restrictions are now restored
•Fixed worktree-isolated subagents redirecting git into the shared checkout via git -C, --git-dir, or GIT_DIR/GIT_WORK_TREE
•Fixed worktree sessions landing in another project's leftover worktree when the working directory did not match the selected project
•Fixed background sessions whose worktree has no git repository being undeletable
•Fixed claude daemon stop --any potentially terminating an unrelated process via a stale legacy daemon lockfile
•Fixed Esc-Esc at an idle prompt not opening the rewind picker in long-running sessions with background tasks
•Fixed Bash command permission checking for compound statements with redirects inside && lists or negations
•Fixed pressing Ctrl+X twice in the agent list failing to delete a session, and deleted sessions reappearing when their background worker had died
•Fixed background subagents getting cancelled when a high-priority message arrives during their startup window
•Fixed mouse and focus garbage in the terminal while a GUI editor from /memory, /plan, /keybindings, or Ctrl+G is open; /memory no longer waits for the editor to close
•Fixed Claude-in-Chrome 403-looping on reconnect when the session's OAuth token lacks a required scope
•Fixed workflow saves and scheduled-task writes following a symlink at .claude, which could redirect writes outside the project
•Fixed MCP re-authenticate revoking working credentials before the new sign-in succeeds, and the reconnect needs-auth message in background sessions pointing at an unusable command
•Fixed read-only commands on Windows accessing network paths without a permission prompt
•Fixed Bash command parsing of non-ASCII characters to match real shell word boundaries
•Fixed PowerShell tool permission validation of commands containing invisible Unicode characters
•Fixed dialogs in fullscreen mode stretching past the right-hand edge of their panel
•Fixed the /config settings list in fullscreen mode clipping its keyboard-hint footer
•Fixed the transcript-mode (Ctrl+O) footer hint wrapping on terminals narrower than 104 columns
•Fixed the Prometheus metrics endpoint (OTEL_METRICS_EXPORTER=prometheus) emitting invalid # UNIT lines
•Fixed skills and commands changed during a session not appearing in the slash menu until restart
•Fixed plugin skills with a name frontmatter field losing their plugin prefix in slash-command autocomplete
•Fixed telemetry misreporting permission denials: failed permission-prompt requests no longer count as user rejections, and user interrupts are now reported as user aborts instead of rejections
•Improved the /fork confirmation to one line with the new session's name, claude attach id, and a note when the copy shares your checkout
•Improved validation of git and gh command arguments in the PowerShell tool
•Improved the /ultrareview diff-too-large error to show configured limits, measured diff size, and largest contributing files
•Improved /code-review ultra empty-diff message to name the exact base ref and suggest passing an explicit base
•Improved the spend limit adjustment prompt to show the server's reason when a spend limit change is rejected
•/context now shows an explicit warning when the conversation exceeds the context window, and a failed /compact displays as an error
•/rewind no longer restores or deletes files through symlinks or hard links at tracked paths and reports how many paths it skipped
•Background sessions: /mcp and /install-github-app now park a "needs input" request in the agent view when no client is attached
•Updated the bundled dataviz skill: reordered the default chart palette and fixed guidance that suggested direct labels for four-series charts
•[VSCode] Fixed right-to-left text (Arabic, Hebrew, Persian) rendering in the wrong order when mixed with English or code
•Fixed cloud sessions dropping the in-flight message when the session's container restarts mid-turn — the interrupted turn now re-runs on resume instead of leaving the session unresponsive

v2.1.215

Claude Code 2.1.215

July 19, 2026

•Claude no longer runs the /verify and /code-review skills on its own; invoke them with /verify or /code-review when you want them

v2.1.214

Claude Code 2.1.214

July 18, 2026

•Fixed single-segment dir/** allow rules like Edit(src/**) auto-approving writes to nested dir/ directories anywhere in the tree instead of only <cwd>/dir
•Fixed a permission-check bypass affecting commands run in Windows PowerShell 5.1 sessions
•Fixed Bash permission checks to fail closed on file-descriptor redirect forms that bash parses differently than the permission analyzer
•Fixed Bash permission checks misjudging very long commands — commands over 10,000 characters now always prompt instead of running automatically
•Fixed Bash permission checks treating zsh variable subscripts and modifiers in [[ ]] comparisons as inert text — these commands now prompt for approval
•Fixed Bash permission checks to no longer auto-approve certain help and man commands that could run unsafe options, command substitutions, or backslash paths
•Fixed permission prompts on remote sessions that could proceed before the local confirmation dialog
•Added the EndConversation tool: Claude can end sessions with highly abusive users or jailbreak attempts, as on claude.ai since 2025 — see https://www.anthropic.com/research/end-subset-conversations
•Added a periodic progress heartbeat for long-running tool calls that previously went silent
•Added an ISO modified timestamp to memory file frontmatter
•Added message.uuid, client_request_id, and tool_source attributes to OpenTelemetry log events for message-level correlation and tool provenance
•Added CLAUDE_CODE_OTEL_CONTENT_MAX_LENGTH to configure the 60 KB truncation limit on OpenTelemetry content attributes
•Added reasoning effort to the subagentStatusLine payload, so custom agent rows can render model and effort
•Added permission prompts for docker commands (including the Podman docker shim) carrying daemon-redirect flags (--url, --connection, --identity, and Podman's remote mode) that previously ran without one
•Fixed a crash when a GrowthBook feature evaluates to null, and a bug where a malformed flag payload could wipe the cached feature flags
•Fixed Bash tool killing the Claude session when a pkill -f pattern accidentally matched the CLI's own process (Linux)
•Fixed unbounded memory growth when --settings points at a device file or multi-GB file; oversized (>2 MiB) settings files now fail at startup with a clear error
•Fixed streaming turns failing with "Socket is closed" behind corporate proxies on Windows
•Fixed stream-json output truncation at exit for slow-reading SDK/pipeline consumers; the exit drain now scales with queued bytes instead of a flat 2s cap
•Fixed scheduled tasks refusing their own configured prompt as untrusted input — the fired prompt is now delivered as the session's assigned task
•Fixed PowerShell tool commands hanging until timeout when a child process waited on standard input (Windows)
•Fixed Python scripts under the PowerShell tool crashing with UnicodeDecodeError when reading non-UTF-8 data from standard input (Windows)
•Fixed Python scripts run via the PowerShell tool crashing with UnicodeEncodeError on non-ASCII output, and PowerShell 7 error messages containing raw ANSI escape sequences (Windows)
•Fixed the PowerShell tool reporting where.exe, fc.exe, and diff.exe as errors when they return a valid negative answer (Windows)
•Fixed > and >> under the PowerShell tool on Windows PowerShell 5.1 writing UTF-16LE files that other tools couldn't read as UTF-8
•Fixed a displaced background daemon deleting its successor's control socket on shutdown, which made the next client kill the healthy replacement daemon
•Fixed background sessions parked with ← or /background and left idle keeping the background daemon and a worker process alive indefinitely
•Fixed completed background sessions being impossible to remove via claude rm or the agent view once the background service had gone idle
•Fixed background sessions dispatched from a non-git folder being impossible to delete from the agents view
•Fixed reopening a stopped background session failing to restore its saved conversation when an unreadable folder exists in the session store
•Fixed the Remote Control "session ready" push notification firing for sessions where Remote Control was not explicitly enabled

•Fixed plugins enabled via the --settings CLI flag not loading (regression since v2.1.181)
•Fixed feature flags going stale in long-running sessions after the OAuth token rotates
•Fixed /ultrareview refusing to run in repos with no merge base — it now offers to review all tracked files
•Fixed claude update and claude doctor hanging silently, and the /status System diagnostics section going blank, when a shell-config path is a directory
•Fixed memory frontmatter values being silently truncated at an inline # when memory files are saved
•Fixed session cost and token telemetry double-counting on streams that emit multiple cumulative message_delta frames
•Fixed a spurious "check your network" warning that appeared while the advisor was thinking
•Fixed hooks with exit code 2 not blocking as documented when the hook's stdout JSON fails schema validation
•Fixed OTel log events emitted outside the turn's async context missing the interaction span's trace context
•Fixed MCP transient errors during prompts/resources refresh clearing the server's slash commands and resources
•Improved the claude rc workspace-trust error in the home directory to say trust there is never saved and to suggest running from a project directory
•Changed single-segment dir/** hook if: conditions to match only <cwd>/dir; write **/dir/** for any-depth matching. deny/ask permission rules keep their any-depth match.
•Changed file commands using -m/--magic-file or -f/--files-from to require permission instead of being auto-allowed as read-only
•Changed keep-alive connection pooling to disable after a stale-connection error, so retries open a fresh socket
•Changed SessionStart hooks to report source "fork" when a session begins as a fork instead of "resume"

v2.1.212

Claude Code 2.1.212

July 16, 2026

•/fork now copies your conversation into a new background session (its own row in claude agents) while you keep working; the in-session subagent it used to launch is now /subtask
•Added claude auto-mode reset to restore the default auto-mode configuration, with a confirmation prompt (pass --yes to skip)
•Added a session-wide limit on WebSearch tool calls (default 200, tunable via CLAUDE_CODE_MAX_WEB_SEARCHES_PER_SESSION) to stop runaway search loops
•Added a per-session cap on subagent spawns (default 200, override with CLAUDE_CODE_MAX_SUBAGENTS_PER_SESSION) to stop runaway delegation loops; /clear resets the budget
•MCP tool calls running longer than 2 minutes now move to the background automatically so the session stays usable; configure the threshold or disable with CLAUDE_CODE_MCP_AUTO_BACKGROUND_MS
•Typing /resume in the agent view now opens a picker of past sessions — including sessions deleted from the list — and resumes your pick as a background session
•Fixed plan mode auto-running file-modifying Bash commands (e.g. touch, rm) without a permission prompt or SDK canUseTool callback
•Fixed worktree creation following a repository-committed symlink at .claude/worktrees, which could create files outside the repository
•Fixed a continue:false hook's halt being dropped when the tool fails or completes mid-stream, and hook infrastructure errors being misreported as user rejections
•Fixed SIGTERM during a running Bash tool orphaning the command's process tree in print/SDK mode; the CLI now aborts the turn, kills the tree, and exits 143
•Fixed /background and claude --bg failing with "EUNKNOWN: unknown error, uv_spawn" on Windows when Group Policy blocks PowerShell 5.1; the daemon now prefers PowerShell 7
•Fixed shell mode (!) not executing commands containing file paths while the path autocomplete popup was open
•Fixed auto-mode denial notifications rendering broken characters when a long denial reason was truncated mid-emoji
•Fixed Ctrl+J not inserting a newline in the agent view dispatch input on terminals with extended key reporting, and surfaced the newline shortcut in the ? help overlay
•Fixed /ultrareview rejecting PR references like #123, PR 123, and pasted PR URLs; error hints now name the command you actually typed
•Fixed /ultrareview <branch> not fetching the branch from origin when it exists remotely; it now suggests the closest branch name on typos
•Fixed /ultrareview skipping the billing confirmation in a new conversation after /clear
•Fixed /ultrareview's "not a git repository" error on Claude Desktop now suggesting the project's repository folder instead of terminal commands
•Fixed hosted (host-managed) sessions failing at startup when repository settings configured mTLS certs, extra CA bundles, or OAuth scopes; these transport settings are now ignored with a warning
•Fixed a spurious "File has not been read yet" error when editing a file that had been read with offset/limit before resuming a session
•Fixed ExitWorktree failing with "no active EnterWorktree session" after resuming a session with --continue/--resume in print/SDK mode
•Fixed the workflow agent grid staying empty for Remote Control clients that join a session mid-run
•Fixed streaming-mode control requests being marked complete before their handler finished, which could lose the request on session restart
•Fixed background sessions created with /fork losing their live-parent protection after a state write failure
•Fixed reopening a stopped background session from the agent view failing silently — it now resumes the session, or shows why it can't and lets you force a restart
•Fixed agent teams: a stopping teammate could send the leader duplicate idle notifications when team initialization re-ran within a session
•Fixed the plan-approval dialog footer splitting "ctrl+g to edit in <editor>" apart when the file path is long
•Fixed the welcome banner keeping its old panel widths after a combined width+height terminal resize in fullscreen mode
•Fixed diff previews losing their line numbers and +/- markers in narrow layouts
•Fixed @-mentions attaching nothing after a partial file read, plugin uninstall targeting the wrong marketplace, and false "Command timed out" on exit code 143
•Fixed OpenTelemetry HTTP exports being rejected with 411/400 by Azure Monitor and other endpoints that don't accept chunked transfer encoding
•Fixed OTLP event log records missing trace_id/span_id when TRACEPARENT is set in SDK/headless mode
•Fixed conversations with many images incorrectly failing with "Request too large" errors, and improved the error message to explain the actual cause
•Fixed web search and web fetch returning "API Error" text as search results or page content when the API was overloaded
•Improved web search and web fetch reliability by retrying 529 errors and rate-limited requests with bounded backoff
•Improved prompt caching: the mid-conversation system block now works behind LLM gateways and custom base URLs (Bedrock, Vertex, 1P)
•Improved background agent attach: cold-attaching now instantly shows the formatted transcript while the session boots, instead of a blank wait
•Reduced token usage in inter-agent messaging: SendMessage bodies are no longer duplicated into replayed history and tool results
•Changed /fork to name the copy after your prompt when the session has no title, so the row is recognizable in the agent view
•Changed bare /btw to reopen the side-question panel on your most recent exchange so you can browse earlier answers
•Changed the ← footer hint to pulse N done for a moment when a background agent finishes while nothing needs your input
•Deprecated the Task tool's mode parameter (now ignored); subagents inherit the parent session's permission mode by default
•Changed Enterprise forceLoginMethod to be enforced for VS Code extension, SDK, setup-token, and install-github-app logins, not just the terminal
•Changed session transcripts to record the reasoning effort level on each assistant message
•Changed headless/SDK sessions to apply a set_model control request mid-turn; the next model round-trip uses the new model instead of waiting for the next turn
•Changed agent view / claude agents --json: sessions waiting on a sandbox, MCP-input, or managed-settings prompt now show as "Needs input" instead of "Working"
•Updated the auth status panel title from "Cloud authentication" to "Authentication"
•Corrected an earlier release note (2.1.200): tmux through the 3.6 series lacks synchronized output; newer tmux with support is detected automatically

v2.1.211

Claude Code 2.1.211

July 15, 2026

•Added --forward-subagent-text flag and CLAUDE_CODE_FORWARD_SUBAGENT_TEXT environment variable to include subagent text and thinking in stream-json output
•Fixed permission previews relayed to chat channels not neutralizing bidirectional-override, zero-width, and look-alike quote characters, so tool inputs cannot visually alter the approval message
•Fixed auto mode overriding a PreToolUse hook's ask decision for unsandboxed Bash — a hook ask now floors the decision at a prompt
•Fixed parallel Claude Code sessions all logging out simultaneously after wake-from-sleep when many sessions share one credential store
•Fixed plugin MCP servers not reconnecting after an idle web session woke, leaving MCP calls failing until the next message
•Fixed Claude Code on Vertex and Bedrock attempting the default Opus model at startup and printing a spurious fallback notice when a model is explicitly configured
•Fixed subagents spawned with an explicit model override reverting to the parent's model when resumed or sent a follow-up message
•Fixed nested .claude/rules/*.md files loading even when setting sources exclude project settings
•Fixed file upload validation: filenames ending in a DOS device suffix (.prn) or trailing dot are now accepted, and files with multiple hard links are refused
•Fixed file uploads to Claude in Chrome from remote and CLI sessions
•Fixed edits that leave the input as "?" being silently swallowed and toggling the shortcuts panel
•Fixed a startup hang when the Claude in Chrome extension is enabled but Chrome is not running
•Fixed a 300ms delay revealing async content (Settings tabs, Stats, diff views, and other loading states)
•Fixed reopening a just-stopped background session from the agents view starting a blank conversation under the same session id
•Fixed /loop hiding the session from /resume after a single use
•Fixed screen reader users losing the audible terminal bell after /terminal-setup or onboarding terminal setup
•Fixed background jobs on LLM gateway auth (ANTHROPIC_AUTH_TOKEN + ANTHROPIC_BASE_URL) coming back "Not logged in" after the daemon respawns them
•Fixed claude agents jobs becoming permanently undeletable when git no longer recognizes their worktree — the row now shows why the delete was refused instead of silently reappearing
•Fixed /clear not resetting the session cost counter — the statusline's cost now starts at $0 after /clear
•Fixed Claude in Chrome setup pages failing to open in the browser on Windows
•Fixed headless print-mode sessions on Windows crashing or silently exiting when stdin is unreadable
•Fixed background session titles in the agents view showing the naming model's refusal text when the prompt contains a link
•Fixed background agents killed by the user auto-respawning, and revived agents re-running stale prompts from old sessions
•Fixed routines with no schedule reporting a next run time in the year 1
•Hardened synced skill/plugin directory naming on Windows and kept CCR web fetch/search proxies working after /clear
•Improved terminal layout and rendering performance
•Improved background agent result reporting — Claude now reports the status of still-running agents and waits for the real completion instead of fabricating results
•Improved the memory index over-limit warning to measure only loaded content, excluding frontmatter and HTML comments
•Updated integer environment variables (timeouts, token budgets, retry counts) to accept scientific notation and digit-separator spellings like 1e6 and 64_000
•Updated documentation links to the current docs sites
•Changed "always allow" permission rules to save at the repository root, so approvals granted in a git worktree persist across sessions and worktrees
•Changed /usage-credits to ask for confirmation before sending a request to organization admins
•Changed Vim mode s and S (substitute char/line) to work in NORMAL mode, matching vim behavior
•[VSCode] Updated the Remote Control banner to describe what it does
•Claude in Chrome: hardened file-upload path validation
•Claude in Chrome: save_to_disk on screenshot actions now writes the image to disk and returns the path; previously it did nothing
•Fixed a prompt-caching regression on Bedrock, Vertex, Mantle, and Foundry that billed the trailing system context block as fresh input tokens on every request.

v2.1.210

Claude Code 2.1.210

July 14, 2026

•Added a live elapsed-time counter to the collapsed tool summary line so long-running tool calls visibly tick instead of looking stuck
•Added a startup warning for Write(path), NotebookEdit(path), and Glob(path) permission rules — use Edit(path) or Read(path) instead
•Fixed isolation: 'worktree' subagents being able to run git-mutating commands against the main repo checkout instead of their own isolated worktree
•Fixed the ultracode keyword opt-in firing on non-human-originated input such as webhook payloads and relayed PR comments
•Fixed a rendered text fragment leaking into crash telemetry when a UI component returned content outside a styled text element
•Fixed paste markers leaking into external editors opened from Claude Code, which could appear as stray È/É characters around pasted text
•Fixed claude attach sometimes failing with "job not found" or "agent is still starting" errors during session transitions — attach now waits for the daemon to settle, and terminal resizes during a slow attach are applied once it completes
•Fixed a session crash when a tool's result renderer returned a numeric bigint value or plain text instead of a UI element
•Fixed a hook callback timeout being misreported to the model as a user rejection, which made unattended sessions stop and wait
•Fixed Claude assuming a cd took effect after its command was moved to the background; the tool result now states the working directory is unchanged
•Fixed plugin-provided MCP servers being torn down when MCP servers are re-synced mid-session
•Fixed plan approvals without edits being labeled "(edited by user)" and overwriting the plan file with a stale snapshot
•Fixed /doctor skipping its auto-mode-default proposal on Bedrock, Vertex, and Foundry, where auto mode no longer needs an opt-in
•Fixed Grep content mode claiming "No matches found" when paginating past the end of results
•Fixed unmatched $1/$2 positional placeholders in skills and commands being silently stripped; they are now preserved verbatim
•Fixed plugin cache writes leaving temp files behind on failure and failing on locked-file renames on Windows and network filesystems
•Fixed background workers crash-looping when a client resets its connection to the background service
•Fixed claude agents --effort ultracode not reaching dispatched sessions; the value was silently dropped
•Fixed pressing ← to open the agents view dropping the task tracker when returning to the session
•Fixed the agents dashboard retaining pasted images from abandoned reply drafts after their session was deleted
•Fixed killed background sessions leaving a permanent git worktree lock behind; the periodic sweep now releases locks whose owning process is gone
•Fixed SDK MCP servers registered via an initialize control request waiting until the next turn to start connecting
•Fixed returning to the agents view from a session leaving overlapping ghost frames with CLAUDE_CODE_DISABLE_ALTERNATE_SCREEN=1
•Fixed late-appearing .claude/* symlinks not being reconciled into the sandbox deny-write list
•Hardened the Agent tool against indirect prompt injection via content a subagent read
•Improved the Bash/PowerShell tool message when a command hits its timeout and is auto-backgrounded, so the model can distinguish a hang from an explicit background request
•Improved auto mode: the permission classifier now defaults to Sonnet 5 for external sessions, validated on the session's first request and pinned for the session
•Improved the bundled dataviz skill's chart color validation with perceptual OKLab color difference and recalibrated color-blindness thresholds
•Memory writes that leave a MEMORY.md index over its read limit now produce an explicit error instead of silent truncation
•Screen reader mode now announces permission mode changes aloud when cycling modes with Shift+Tab
•The agents footer hint now shows how many background agents are waiting on your input, with a brief color emphasis when the count changes
•Agent view: the session you pressed ← from stays visibly marked even after mouse hover or arrow keys move the selection
•Fable temporarily shows as unavailable in the advisor picker while a server-side issue causing Fable advisor failures is fixed

v2.1.209

Claude Code 2.1.209

July 14, 2026

•Fixed /model and other dialogs being blocked in claude agents background sessions (reverts an overly broad guard)

v2.1.208

Claude Code 2.1.208

July 13, 2026

•Added screen reader mode: opt-in plain-text rendering for screen reader users. Run claude --ax-screen-reader, set CLAUDE_AX_SCREEN_READER=1, or add "axScreenReader": true to settings.
•Added vimInsertModeRemaps setting: map two-key insert-mode sequences like jj to Escape in vim mode
•Added CLAUDE_CODE_PROCESS_WRAPPER: agent view and the background service now honor a corporate launcher by running every Claude Code self-spawn through a required wrapper executable
•Added mouse-click support for multi-select menus and "Other" input rows in fullscreen mode
•Changed the Fable 5 usage-credits consent prompt to start with the decline option focused
•Fixed fast mode staying off after switching back to a model that supports it — it now restores automatically when enabled in settings
•Fixed replies typed to a background agent being lost when delivery fails — the text is now saved and delivered when the session restarts
•Fixed background-session attach failing permanently ("Couldn't start the background daemon") after an update replaced the binary a running claude agents process was launched from
•Fixed the context window (and auto-compact indicator) briefly resetting to 200k after the CLI auto-updates, causing a false "100% context used" when resuming long-context sessions
•Fixed supervised and background sessions crashing when a server closed an HTTP/2 connection with a GOAWAY while requests were in flight
•Fixed truncated stream-json/JSON output and missing result message when piping large responses from claude -p
•Fixed CLAUDE_CODE_MAX_OUTPUT_TOKENS and similar env vars silently using the mantissa of scientific-notation values (1e6 became 1)
•Fixed very large markdown tables stalling rendering or using excessive memory; tables over 200 rows show the first 200 with a "… N more rows" notice
•Fixed the Edit tool failing on files modified after reading when the target text still matches uniquely
•Fixed Read reporting empty files as "shorter than offset", Grep silently returning "No files found" for invalid regex patterns, Grep count mode under-reporting totals when paginated, and Glob crashing with an unclear error when the pattern, path, or working directory contained a null byte
•Fixed apiKeyHelper script failures being hidden behind a generic 401 after ~10 silent retries; the script's own error is now shown within 3 attempts
•Fixed Bedrock streaming requests failing with a misleading "Truncated event message received" when a gateway transforms the response — the error now names the content-type and points at the proxy
•Fixed /upgrade showing a login flow instead of the upgrade URL when the browser fails to open
•Fixed stream-json input killing the session on blank CRLF or whitespace-only lines from Windows-style SDK hosts
•Fixed headless stream-json sessions hanging permanently when a control_request carried a non-string set_model payload; the CLI now answers with an error response
•Fixed repeated "No completion record was found" notices on session resume — orphaned background tasks now collapse into a single summary
•Fixed Remote Control clients attaching to a terminal-hosted session not seeing background agents and workflow progress until a task started or stopped
•Fixed the Agent tool launching with no tools when a subagent's tools list resolves to nothing — it now returns a clear error naming the unrecognized entries
•Fixed /usage showing stale cached bars over fresher data, and /mcp not reclassifying placeholder servers after config edits
•Fixed "Change directory" in SDK hosts (e.g. Claude Desktop) failing with "A turn is in progress" on idle sessions that have a running background task
•Fixed the workflow save dialog showing ~/.claude/workflows/ instead of the CLAUDE_CONFIG_DIR location for user-scope saves
•Fixed /release-notes adding the viewed notes to the model's context — "Show all" previously injected the entire changelog into every subsequent request
•Fixed a memory leak in the agent view where pasted images were retained for the screen's lifetime after sending peek replies
•Fixed SDK sessions losing agents defined via the initialize request when a plugin refresh ran before the client attached
•Fixed several memory leaks in long sessions: MCP stdio server stderr accumulating up to 64 MB per server, LSP documents staying open indefinitely (now LRU with 50-doc cap), async hook output retained after backgrounding, and unbounded growth in headless/SDK sessions from large tool-result payloads
•Fixed a memory blowup when reading files with extremely long single lines using offset/limit — the read now returns a clean error instead of loading the whole line
•Fixed multi-second per-turn slowdowns in sessions with many permission deny/ask rules — rule matchers are now compiled once and cached
•Improved input responsiveness while agent task lists update — task updates no longer re-render the entire UI
•Reduced per-tool-call CPU overhead in print/SDK sessions with many MCP tools by caching tool-pool assembly (up to 7x faster tool rounds at high tool counts)
•Reduced memory usage by bounding the file edit read cache to 16 MB instead of pinning up to 1,000 full files
•Reduced session transcript size (up to 79x in edit-heavy sessions) and bounded checkpoint disk usage by pruning superseded file-history backups
•Reduced memory usage when resuming sessions with background agents or forks spawned from large conversations
•Completed background agents now stay listed in /tasks until cleanup instead of vanishing the moment they finish
•Attaching to a stopped background agent now shows its transcript immediately while the session warms up, instead of a blank "Session is starting" screen
•Background sessions: an older daemon no longer silently restarts workers spawned by a newer version onto the older binary
•Agent view: Ctrl+X now deletes renamed-branch worktrees, never destroys unpushed commits, keeps the session row when a worktree is kept, and reused worktree names reset to the current base
•Catastrophic removals (e.g. rm -rf ~) in commands containing $(…)/backticks/<(…) now prompt in --dangerously-skip-permissions and auto mode, matching the plain form
•/install-github-app and the /mcp settings menu no longer open in background sessions
•MCP servers configured with an empty URL now show as "not configured" in /mcp instead of a config error
•/usage now shows your last-known usage bars with an "as of" note when the usage endpoint is rate-limited, instead of an error screen
•Fixed Bedrock auth failing with "Session token not found or invalid" for AWS SSO profiles whose sso_region differs from the Bedrock region (2.1.207 regression)

v2.1.207

Claude Code 2.1.207

July 10, 2026

•Auto mode is now available without CLAUDE_CODE_ENABLE_AUTO_MODE opt-in on Bedrock, Vertex AI, and Foundry; disable via disableAutoMode in settings
•Fixed the terminal freezing and keystrokes lagging while streaming responses containing very long lists, tables, paragraphs, or code blocks
•Fixed remote managed settings from a non-interactive run (claude -p, the SDK) being permanently recorded as consented without ever showing the security consent dialog
•Fixed spurious prompt-injection warnings triggered by benign system-generated conversation updates
•Fixed the auto-updater overwriting a custom launcher script or symlink at ~/.local/bin/claude on every release; /doctor now reports an externally managed launcher
•Fixed compound commands with cd prompting for permission when the only output redirect was to /dev/null
•Fixed the transcript jumping above the start of the answer when a response finishes streaming
•Fixed extensions.worktreeConfig being left in the repo's .git/config (breaking go-git tools like tea) after the last worktree.sparsePaths worktree was removed
•Fixed malformed bracket patterns in rules globs, skill paths, .ignore, and .worktreeinclude breaking file reads, file suggestions, and worktree creation
•Fixed a crash loop in agent teams where a malformed teammate mailbox message caused repeated errors every second until the mailbox file was manually deleted
•Fixed background sessions auto-named by accepting a plan not showing that name on their agent-view row
•Fixed background sessions that entered a git worktree resuming blank after a cold reopen from the agent list
•Fixed Remote Control task status updates being lost when the connection recovered from a network interruption or credential refresh
•Fixed Remote Control sessions hosted by the desktop app not showing background agent and workflow progress on mobile and web
•Fixed Deep research runs labeling every Fetch-phase agent "unknown" — chips now show the source hostname
•Fixed Bedrock repeatedly requesting fresh AWS SSO credentials from IAM Identity Center on every API request
•Improved agent view: pasting the same text again now expands the collapsed [Pasted text #N] placeholder instead of adding a second one
•Improved agent view: blocked session peeks now lead with the question and show a worded staleness clock (waiting 3m) instead of the same timestamp twice
•Changed Bedrock, Vertex, and Claude Platform on AWS to default to Claude Opus 4.8
•Changed auto mode to no longer read autoMode from .claude/settings.local.json (repo-resident); use ~/.claude/settings.json instead
•Fixed an indefinite hang on Windows when AWS credential resolution stalls (e.g. a stuck credential_process): the 60-second stall guard now fires instead of waiting forever.
•Plugin hooks/monitors/MCP headersHelper: ${user_config.*} in shell-form commands is now rejected (shell-injection fix). Hooks: use exec form (args array) or $CLAUDE_PLUGIN_OPTION_<KEY>; monitors and headersHelper: read the value inside the script (config file or the server's env block).
•Plugin option values (pluginConfigs) are no longer read from project-level .claude/settings.json; only user, --settings, and managed settings are honored
•Fixed /usage-credits amount inputs silently stripping malformed values (e.g. a pasted timestamp) to digits; malformed amounts are now rejected with an error, and amounts over $1,000 require a typed confirmation

v2.1.206

Claude Code 2.1.206

July 9, 2026

•Added directory path suggestions to /cd, matching /add-dir behavior
•Added a /doctor check that proposes trimming checked-in CLAUDE.md files by cutting content Claude could derive from the codebase
•/commit-push-pr now auto-allows git push to the repo's configured push remote (remote.pushDefault, or the sole remote when only one is configured) in addition to origin
•Gateway: /login now supports Anthropic-operated public gateway endpoints
•EnterWorktree now asks for confirmation before entering a git worktree outside the project's .claude/worktrees/ directory

•Fixed claude --resume and --continue not responding to keyboard input on startup
•Fixed MCP servers configured via --mcp-config or .mcp.json ignoring a per-server request_timeout_ms, which caused long-running MCP tool calls to time out at the 60s default in fresh sessions
•Fixed CLAUDE_CODE_EXTRA_BODY being silently ignored by claude agents / --bg background workers; the shell-exported override now follows the dispatching session
•Fixed OAuth MCP servers requiring manual re-authentication after a single failed token refresh
•Fixed --permission-prompt-tool pointing at an MCP server crashing with "MCP tool not found" on cold start before the server finishes connecting
•Fixed /model picker rows printing a price for a different model than the row named, and stopped quoting first-party list prices on providers that don't bill them

•Fixed /status listing the same broken-install warning twice
•Fixed false "disused plugin" tips and skewed disuse telemetry for LSP plugins
•Fixed /doctor's update check to compare Homebrew installs against their cask's channel instead of the settings channel

•Bedrock: fixed a multi-minute startup hang when using an awsCredentialExport helper on networks with restricted egress
•Improved /code-review findings quality on claude-opus-4-8 across all effort levels
•Improved agents view: status column now uses full terminal width instead of truncating at 64 characters
•Changed agents view: Ctrl+X now permanently removes a completed session, and sessions no longer render twice; deleted background jobs stay deleted

v2.1.205

Claude Code 2.1.205

July 8, 2026

•Added an auto mode rule that blocks tampering with session transcript files

•Improved auto mode to ask before running rm -rf on a variable it can't resolve from context
•Auto-update binary downloads now stream to disk instead of buffering in memory, cutting the updater's peak memory usage by roughly 400 MB
•Background task notifications now explicitly state that no human input has occurred, preventing fabricated in-transcript approvals from being acted on
•Improved agent view: sessions that edit, merge, comment on, or push to an existing PR now link it in claude agents
•Improved agent view: rows now show a colored state word and a classifier-written headline instead of raw tool call text, and the peek opens with full status including the exact ask for blocked sessions
•/doctor is now a full setup checkup that can diagnose and fix issues; /checkup is its alias
•Reserved the "Claude Browser" MCP server name (alongside "Claude Preview") ahead of the Claude Desktop pane rename; user-configured MCP servers can no longer register under either name

v2.1.204

Claude Code 2.1.204

July 8, 2026

•Fixed hook events not streaming during SessionStart hooks in headless sessions, which could cause remote workers to be idle-reaped mid-hook

v2.1.203

Claude Code 2.1.203

July 7, 2026

•Added a warning when your login is about to expire, so you can re-authenticate before background sessions are interrupted
•Added a grey ⏸ badge to the footer when in manual permission mode, making the active mode always visible
•Added the session's additional working directories to MCP roots/list, with notifications/roots/list_changed sent when the set changes
•Fixed opening or switching background agent sessions on macOS stalling for 15–20 seconds due to a false low-memory detection (regression in 2.1.196)
•Fixed background sessions becoming permanently unresponsive to attach, replies, and stop when the daemon's session token went stale — the session now recovers automatically
•Fixed returning to claude agents silently stopping running subagents and re-running the prompt from scratch — their work now carries over
•Fixed a memory and per-turn CPU regression in interactive sessions: the context-usage indicator no longer re-analyzes the entire transcript after every turn
•Fixed background agents inheriting a stale PATH from the daemon instead of the dispatching shell, causing missing tools on Windows
•Fixed background and agent-view sessions dropping a shell-exported ANTHROPIC_BASE_URL, which sent API keys to the default endpoint and failed with 401
•Fixed Bash failing with "argument list too long" in repos with many git worktrees
•Fixed worktree-isolated subagents sometimes running shell commands in the parent checkout instead of their own worktree
•Fixed worktree creation rejecting nested repositories in multi-repo workspaces, leaving background sessions unable to isolate and edit
•Fixed background agents crash-looping when their working directory was deleted, replaced by a file, or became an invalid path — they now fail once with a clear error
•Fixed a background daemon auto-upgrade failure silently killing all running background sessions
•Fixed TaskStop and TaskOutput failing to find background agents spawned by another agent — errors now list running agents by id and description
•Fixed the claude agents composer discarding your typed message when a slash command isn't available there
•Fixed the agent list crashing when opening a stopped session whose conversation was already open in another session
•Fixed background sessions showing "Needs input" in the agent list after the question was already answered

•Fixed the terminal flickering and jumping while typing in bash mode when a shell-history suggestion was shown
•Fixed literal ^[[I / ^[[O escape codes being printed when reattaching to a background session
•Fixed LSP-only plugins being incorrectly flagged for disuse when their language servers deliver diagnostics or answer navigation requests
•Improved responsiveness while long responses stream: live-preview updates no longer re-render the whole screen
•Improved subagent behavior: agents are now less likely to re-delegate their entire task to another subagent
•Reduced binary size by ~7 MB and startup memory by ~7 MB by loading a large bundled dependency lazily instead of inlining it
•Changed left arrow to no longer close the background tasks, diff, and workflow detail views — press Esc instead
•Changed the empty claude agents view to always show the organized sections (Needs input / Working / Completed) with descriptions
•Removed the startup "claude command missing or broken" warnings — they now appear in /doctor and /status instead
•Removed a redundant navigation hint from the claude agents footer
•[VSCode] Added a Settings toggle for "Enable Remote Control for all sessions"

v2.1.202

Claude Code 2.1.202

July 6, 2026

•Added a "Dynamic workflow size" setting in /config for controlling how large Claude generally makes dynamic workflows (small/medium/large agent counts) — an advisory guideline, not an enforced cap
•Added workflow.run_id and workflow.name OpenTelemetry attributes to telemetry emitted by workflow-spawned agents, so a workflow run's activity can be reconstructed from OTel data
•Fixed a crash in the inline Ctrl+R history search when accepting or cancelling while the search was still scanning the history file
•Fixed /rename on background sessions being reverted when the job restarts, which broke addressing the session by its new name
•Fixed transient mTLS handshake failures when settings were re-applied during an in-place client certificate rotation
•Fixed commands sent from Remote Control (mobile/web) into an interactive session failing with "Unknown command"
•Fixed images and files sent from the Remote Control mobile or web app without a caption being silently dropped
•Fixed the sign-in URL printed by claude auth login and claude mcp login --no-browser not being reliably clickable when it wraps over SSH — it is now emitted as a single hyperlink
•Fixed opening a chat from claude agents sometimes failing with "currently running as a background agent" followed by a worker crash/respawn loop
•Fixed workflow scripts with unicode quote escapes in strings being corrupted before parsing; workflow parse errors now show the offending line instead of always blaming TypeScript
•Fixed voice dictation retrying in an unbounded loop when the microphone or audio recorder fails — repeated capture failures now pause voice input
•Fixed /remote-control sessions showing the wrong permission mode in the mobile and web apps
•Fixed resuming a session by name, or opening the resume picker, taking minutes and using a large amount of memory in repositories with many git worktrees
•Fixed installer and updater downloads failing immediately with "aborted" when a proxy or network drops the connection mid-download — transient connection drops now retry
•Fixed re-invoking an already-loaded skill appending a duplicate copy of its instructions to context
•Improved /workflows agent list layout: wider titles, a dedicated time column, shorter model names, and no per-row tool-call counts
•Improved MCP error messages: clearer error when a server config has url but no type, suggesting "type": "http" instead of the misleading "command: expected string"
•Changed /review <pr> back to a fast single-pass review; use /code-review <level> <pr#> for the multi-agent review at a chosen effort level

v2.1.201

Claude Code 2.1.201

July 3, 2026

•Claude Sonnet 5 sessions no longer use the mid-conversation system role for harness reminders

v2.1.200

Claude Code 2.1.200

July 3, 2026

•Changed AskUserQuestion dialogs to no longer auto-continue by default; opt into an idle timeout via /config
•Changed the "default" permission mode to "Manual" across the CLI, --help, VS Code, and JetBrains; --permission-mode manual and "defaultMode": "manual" are accepted alongside default
•Fixed a crash at startup when disabledMcpServers or enabledMcpServers in .claude.json is set to a non-array value
•Fixed background sessions silently stopping mid-turn after sleep/wake or when reopening a stalled session
•Fixed background sessions re-running a turn cancelled with Esc after a stall respawn
•Fixed background agents never starting again after a crash left a stale daemon.lock whose PID the OS reused
•Fixed background-agent daemon handover so a reinstalled older build can no longer take over the daemon; build recency is now judged by the version's embedded build timestamp
•Fixed background-agent roster issues: transient corruption permanently disabling orphan cleanup, older binaries not preserving fields written by newer versions, and socket auth tokens being stripped during daemon restarts
•Fixed subagents cut off by a rate limit before producing any text output returning an empty result instead of failing cleanly
•Fixed control bytes from background-agent output reaching the terminal in the agent view
•Fixed claude agents --plugin-dir <dir> not showing the plugin's agents and skills in the agent view when the flag is placed after agents
•Fixed project-scoped plugins not loading correctly from git worktrees of the same repository
•Fixed /mcp server list not tracking focus for screen readers and magnifiers
•Fixed voice dictation showing a misleading "Voice connection failed" message when a recording captures no audio
•Fixed rendering flicker under tmux 3.4+ by enabling synchronized terminal output
•Improved screen-reader output: decorative glyphs are now hidden, transcript symbols read as short labels, and nested tables read as Header: value. lines
•Improved the install script to explain when installation is killed by the system running out of memory

v2.1.199

Claude Code 2.1.199

July 2, 2026

•Stacked slash-skill invocations like /skill-a /skill-b do XYZ now load all leading skills (up to 5), not just the first
•Fixed SSL certificate errors (TLS-inspecting proxies, missing NODE_EXTRA_CA_CERTS, expired certs) burning retries before showing actionable guidance — they now fail immediately with the fix hint
•Fixed streaming responses being discarded when the API emits a mid-stream overloaded/server error after partial output — the partial is now kept with an incomplete-response notice
•Fixed subagents cut off by a rate limit or server error silently failing instead of returning their partial work to the parent
•Fixed subagents reporting API errors (e.g. usage limit reached) as successful results — the error is now reported to the parent agent
•Fixed the background-agent daemon on Linux killing itself and every running agent every ~50 seconds after an unclean shutdown left a corrupted worker record
•Fixed background agents failing to cold-start over SSH on macOS with "Could not switch to audit session" (regression in 2.1.196)
•Fixed claude stop being silently undone when it raced a background-agent respawn — the respawn now honors the stop
•Fixed background job progress indicators stalling for minutes while the job ran long commands
•Fixed background sessions on memory-starved machines showing a generic error — they now indicate low memory and suggest freeing resources
•Fixed remote sessions briefly flapping between Working and Idle in the agent view when a background agent completes
•Fixed idle subagents vanishing from the agent panel while other subagents were still working; surplus idle agents now collapse into an expandable summary row
•Fixed typing /model or /fast while viewing a subagent silently opening the lead's model picker — a notice now explains the command applies to the lead
•Fixed SessionStart, Setup, and SubagentStart hooks silently hiding stderr when exiting with code 2 — the error is now shown in the transcript
•Fixed claude --dangerously-skip-permissions daemon <subcommand> being treated as a chat prompt instead of running the subcommand
•Fixed SendMessage silently misrouting when a re-spawned agent reuses a previous agent's name — the tool now detects the mismatch and asks the caller to retarget
•Fixed opening or resuming a session with no new messages needlessly growing the transcript file
•Fixed backgrounding a session with ← or /background dropping its /color from the agent view row
•Fixed resetting a corrupted config file from the startup recovery dialog destroying it unrecoverably — it now backs up the file first
•Fixed Claude in Chrome repeatedly opening the reconnect page when sessions run from different builds or config directories
•Fixed plan mode not prompting for state-changing browser tool calls; read-only browser_batch calls are now correctly auto-allowed
•Transient server rate-limit errors (429s unrelated to your usage limit) are now retried automatically with backoff for subscribers instead of failing the turn
•CLAUDE_CODE_RETRY_WATCHDOG now raises the default retry count for non-capacity transient errors to 300 and lifts the cap of 15 on CLAUDE_CODE_MAX_RETRIES
•claude agents session rows now show pull-request links as bare #N without the redundant "PR" label

v2.1.198

Claude Code 2.1.198

July 1, 2026

•Subagents now run in the background by default, so Claude keeps working while they run and is notified when they finish (previously a gradual rollout)
•Claude in Chrome is now generally available
•Added background agent notifications in claude agents — sessions that need input or finish now fire the Notification hook (agent_needs_input / agent_completed)
•Added /dataviz skill for chart and dashboard design guidance with a runnable color-palette validator
•Gateway: added Claude Platform on AWS (anthropicAws) as an upstream provider; model-not-found responses now advance the failover chain
•Background agents launched from claude agents now commit, push, and open a draft PR when they finish code work in a worktree, instead of stopping to ask
•The built-in Explore agent now inherits the main session's model (capped at opus) instead of running on haiku
•Subagents and context compaction now inherit the session's extended thinking configuration, improving output quality on delegated tasks
•Fixed brief network drops mid-response aborting the turn — transient errors like ECONNRESET now retry with backoff instead of failing
•Fixed excessive background classifier requests when sandboxed processes repeatedly accessed the same network host
•Fixed background tasks in web, desktop, and VS Code task panels getting stuck on "Running" after they finish or after resuming a session
•Fixed agent teams: a teammate that dies on an API error now reports "failed" to the lead, and messaging a stuck teammate wakes it to retry immediately
•Fixed the /diff panel not refreshing when you switch branches or commit outside the session
•Fixed markdown tables overflowing and wrapping their right border when rendered in fullscreen mode
•Fixed Claude Platform on AWS and Mantle sessions dead-ending with "Please run /login" when the STS token expires — awsAuthRefresh now runs automatically
•Fixed "no route to host" for local-network hosts in macOS background agent sessions by declaring Local Network entitlements
•Fixed /desktop failing with "Cannot determine working directory" after entering and exiting a worktree
•Fixed background agents repeatedly showing "Reconnecting…" every ~52 seconds on macOS while the agents view was open
•Fixed pressing ← inside claude attach <id> exiting to the shell instead of opening the agent view
•Fixed claude --bg silently creating an unattachable session when combined with --print/-p; the conflicting flags are now rejected up front

•Fixed .claude/rules/ conditional rules not loading when the target file is reached via a symlinked path
•Fixed Cmd+click not opening URLs in fullscreen mode in Warp on macOS
•Fixed double-click word selection in fullscreen mode to select the entire URL including the scheme
•Fixed plan mode not auto-allowing read-only tool calls when a session starts in plan mode
•Fixed /branch deriving its default fork name from the compaction summary instead of the first real prompt
•Improved focus mode: subagents launched in a turn now appear in its activity summary, and completed background notifications fold into a single count
•Improved syntax highlighting accuracy in code blocks, diffs, and file previews by upgrading to highlight.js 11
•Keyboard shortcut hints now show opt/cmd instead of alt/super when connected from a Mac over SSH
•Improved API retry UX: the error reason is now shown after the second attempt, and a status page link replaces the spinner tip when the API is overloaded
•/login now opens the sign-in dialog from the claude agents view instead of saying it isn't available
•Subagents now treat messages from the agent that launched them as normal task direction; an agent's message is still never treated as the user's approval
•Removed the /agents wizard; ask Claude to create or manage subagents, or edit .claude/agents/ directly
