v2.1.152New

Claude Code 2.1.152

May 27, 2026

•/code-review --fix now applies review findings to your working tree after the review, surfacing reuse, simplification, and efficiency suggestions; /simplify now invokes /code-review --fix
•Skills and slash commands can now set disallowed-tools in frontmatter to remove tools from the model while the skill is active
•Added /reload-skills command to re-scan skill directories without restarting the session
•SessionStart hooks can now return reloadSkills: true to re-scan skill directories, making skills installed by the hook available in the same session
•SessionStart hooks can now set the session title via hookSpecificOutput.sessionTitle on startup and resume
•Added a MessageDisplay hook event that lets hooks transform or hide assistant message text as it is displayed
•Added pluginSuggestionMarketplaces managed setting: admins can allowlist org marketplaces whose plugins may be suggested via context-aware tips
•claude plugin marketplace remove now accepts --scope user|project|local for symmetry with marketplace add, install, and uninstall
•Claude Code now switches to your configured --fallback-model for the rest of the session when the primary model is not found, instead of failing every request
•Auto mode no longer requires opt-in consent
•Vim mode: / in NORMAL mode now opens reverse history search (like Ctrl+R), matching bash/zsh vi-mode
•The /usage breakdown now includes large session files; files are scanned with a streaming read so memory usage stays flat
•Thinking summaries in the collapsed group now stay readable for at least 3 seconds, render as markdown, and cap at 10 lines (Ctrl+O shows the full thinking)
•In fullscreen mode, the "Thinking for Ns" indicator now counts up live while the model is thinking, and keeps its value if you interrupt mid-thought
•Simplified the Workflow tool's inline progress display — live agent counts now show only in the persistent workflow status row below the prompt
•The post-response timer now shows "Waiting for N background agents/workflows to finish" when backgrounded agents or workflows are still running, and reports the cumulative time once their results are processed
•Added the session entrypoint as an OpenTelemetry metric attribute (app.entrypoint, opt-in via OTEL_METRICS_INCLUDE_ENTRYPOINT=true)
•Fixed terminal styling degrading in very long sessions by recycling the renderer's style pool
•Fixed the sandbox-enabled warning not appearing in condensed startup mode — it now shows in every layout
•Fixed the loading spinner showing "still thinking"/"almost done thinking" while a tool is running, and reset the thinking status to "thinking" after each tool
•Fixed focus mode showing a spurious "N messages hidden" count on turns with no hidden activity
•Fixed clicking a link inside an expanded tool result collapsing the section instead of opening the link
•Fixed markdown table cell borders inheriting the color of inline code, wrapped continuation lines losing their style, and empty header cells showing a label in the narrow-terminal stacked layout
•Fixed plugin MCP servers with the same command but different environment variables being incorrectly deduplicated
•Fixed /doctor reporting "marketplace not found" or "plugin not found" for stale enabledPlugins entries referencing removed marketplaces or dropped plugins
•Fixed plugins that track a git branch silently no longer receiving updates after the plugin registry was rebuilt
•Fixed remote MCP servers failing to connect in Claude Code Remote sessions when the egress proxy is enabled
•Fixed the effort-change confirmation dialog appearing when the conversation has no messages or when switching between effort levels that resolve to the same underlying value
•Fixed the Agent tool description referencing an agent list that is never delivered when running with --bare or with attachments disabled
•Fixed a background worker crash in claude agents when accepting a stale permission prompt after a subagent was cancelled
•Fixed cache_creation_input_tokens reporting as 0 in transcript and result usage when the API reports cache writes only via the nested cache_creation breakdown
•Fixed the PushNotification tool incorrectly reporting "Mobile push not sent (Remote Control inactive)" in SDK-hosted sessions when Remote Control is enabled
•Fixed sessions getting stuck after a model or login switch left stale thinking-block signatures in history; now stripped proactively with a retry safety-net

v2.1.150New

Claude Code 2.1.150

May 23, 2026

•Internal infrastructure improvements (no user-facing changes)

v2.1.149New

Claude Code 2.1.149

May 22, 2026

•/usage now shows a per-category breakdown of what's driving your limits usage — skills, subagents, plugins, and per-MCP-server cost
•/diff detail view can now be scrolled with the keyboard (arrows, j/k, PgUp/PgDn, Space, Home/End)
•Markdown output now renders GFM task list checkboxes (- [ ] todo / - [x] done) instead of plain bullets
•Enterprise: added the allowAllClaudeAiMcps managed setting to load claude.ai cloud MCP connectors alongside managed-mcp.json
•Fixed a PowerShell permission bypass: built-in cd functions (cd.., cd\, cd~, X:) changed the working directory undetected, letting a later command read outside the workspace
•Fixed the sandbox write allowlist in git worktrees covering the entire main repository root instead of only the shared .git directory (with hooks/ and config denied)
•Fixed PowerShell prefix/wildcard allow rules (e.g. PowerShell(dotnet.exe build *)) not pre-approving native executables and scripts
•Fixed a permission-analysis gap where the parser trusted stale variable-tracking values for PWD/OLDPWD/DIRSTACK across cd/pushd/popd
•Fixed find in the Bash tool exhausting the macOS system file/vnode table and crashing the host on large directory trees
•Fixed the managed-settings approval dialog leaving the terminal frozen after accepting at startup
•Fixed /ultraplan and remote session creation failing with "Could not capture uncommitted changes" when the working tree has no real changes
•Fixed otelHeadersHelper failing silently when the script path contains spaces; helper failures are now reported in /doctor and the debug log
•Fixed the thinking spinner staying amber across tool calls and onto fresh thinking bursts
•Fixed collapsed Bash output reporting the wrong hidden-line count for outputs with many short lines
•Fixed slash-command argument-hint clipping trailing typed characters when the hint overflows the input box
•Fixed argument-hint and progressive arg suggestions not appearing after Tab-completing a skill whose frontmatter name: differs from its directory basename
•Fixed the status bar showing the user's baseline /effort setting instead of the effort level applied by skill/agent effort: frontmatter
•Fixed Ctrl+O transcript view freezing at the moment it was opened instead of tailing new messages
•Fixed editing a recalled prompt-history entry losing the edit when navigating further up/down with arrow keys
•Fixed /config exit summary reporting phantom changes to auto-compact and theme when toggling unrelated settings
•Fixed /insights crashing when cached session-meta files are missing optional fields
•Fixed malformed PowerShell and History tool calls with missing input being misclassified as reads in transcript collapsing
•Fixed renaming a Remote Control session from claude.ai or the Claude mobile app not updating the local session name for claude --resume
•Fixed a race where a just-submitted prompt could appear twice in the up-arrow history
•Fixed tapping the "Jump to bottom" pill in fullscreen mode not dismissing it immediately
•Improved /feedback reports to include the conversation that happened before context compaction, making issues from earlier in long sessions easier to triage

v2.1.148New

Claude Code 2.1.148

May 22, 2026

•Fixed the Bash tool returning exit code 127 on every command for some users (a regression introduced in 2.1.147)

v2.1.147New

Claude Code 2.1.147

May 21, 2026

•Pinned background sessions (Ctrl+T in claude agents) now stay alive when idle, are restarted in place to apply Claude Code updates, and are shed under memory pressure only after non-pinned sessions
•Renamed /simplify to /code-review. It now reports correctness bugs at a chosen effort level (e.g., /code-review high); pass --comment to post findings as inline GitHub PR comments. The old cleanup-and-fix behavior has been removed
•Improved auto-updater: retries transient network failures, reports specific error categories and OS error codes on failure, and shows the current version when an update fails
•Improved diff rendering performance for large file edits
•Prompt history no longer records consecutive duplicate entries — recalling a prompt with arrow-up and submitting it again won't add another copy
•Fixed enterprise login restrictions (forceLoginOrgUUID and forceLoginMethod managed-settings) not being enforced against third-party-provider and API-key sessions
•Fixed & in ! command output displaying as &, which broke copy-pasting URLs from commands like gcloud auth login on headless machines
•Fixed unknown slash commands silently doing nothing in headless/SDK mode — they now show an error message
•Fixed /help rendering a broken tab header and showing only one command per page on small terminals when not in fullscreen mode
•Fixed shell snapshot dropping user functions whose names start with a single underscore, which broke aliases referencing them
•Fixed plugin agents that declare multiple Agent(...) types in tools: frontmatter dropping all but the last entry
•Fixed hook if conditions like PowerShell(git push*) never matching — only PowerShell(*) worked
•Fixed PowerShell tool dropping output for commands that rely on the default formatter
•Fixed: on Windows, "Yes, and don't ask again" for a PowerShell script invocation now writes a rule that actually matches on subsequent runs
•Fixed PowerShell tool failing on Windows with exit code 1 when pwsh is installed via winget or the Microsoft Store
•Fixed /effort opening with the slider on the wrong level — it now starts at your current effort
•Fixed paginating MCP servers dropping resources, templates, and prompts past page 1
•Fixed full-screen strobing in attached background sessions on Windows Terminal while Claude is streaming
•Fixed: on Windows, removing a background-job worktree no longer follows NTFS junctions into the main repo
•Fixed /background refusing sessions whose only typed input was a skill or custom slash command
•Fixed auto mode suppressing AskUserQuestion when the user or a skill explicitly relies on it; the auto-mode classifier now sees the user's answers as intent signal
•Fixed /theme "New custom theme" and color editor dialogs not responding to Esc
•Fixed an uncaught exception at the end of streaming sessions when running via the Agent SDK
•Fixed a rare hang when waiting for scroll to settle on Windows
•Fixed stale and doubled rows in the agent view list on Windows when background session results contain wide (CJK) characters
•Fixed pasted text being delivered to agents as an unreadable [Pasted text #N] placeholder instead of the actual content
•Fixed plugin component counts in claude plugin details and /plugin being doubled when a plugin's manifest listed paths overlapping its default directories
•Fixed backgrounded sessions re-prompting for tool permissions you already granted with "don't ask again"
•Fixed GNOME Terminal right-click and middle-click paste not inserting text
•Fixed CLAUDE_CODE_SUBAGENT_MODEL not applying to teammate processes spawned by agent teams
•Fixed slash commands followed by a tab or newline being treated as an unknown command
•Fixed several spacing and layout glitches in the /plugin, /status, /mobile, /sandbox, and /permissions menus
•Fixed stripped images prompting the model to repeatedly re-read media that was no longer present

v2.1.145

Claude Code 2.1.145

May 19, 2026

•Added claude agents --json to list live Claude sessions as JSON for scripting (tmux-resurrect, status bars, session pickers)
•Added agent_id and parent_agent_id attributes to claude_code.tool OTEL spans, and fixed trace parenting so background subagent spans nest under the dispatching Agent tool span
•Status line JSON input now includes GitHub repo and PR information when detected
•/plugin Discover and Browse screens now show a plugin's commands, agents, skills, hooks, and MCP/LSP servers before installation
•claude agents terminal tab title now shows the awaiting-input count so an alt-tabbed window tells you when an agent needs attention
•Slash command and @-mention suggestion list now supports mouse hover and click in fullscreen mode
•Stop and SubagentStop hook input now includes background_tasks and session_crons fields
•Fixed a permission-prompt bypass where bare variable assignments to non-allowlisted environment variables in Bash commands were auto-approved
•Fixed MCP prompt slash commands showing raw server validation errors when a required argument is omitted — the error now names the missing argument and shows expected usage
•Fixed the spinner and elapsed-time display freezing until a keypress after the terminal was resized or refocused
•Fixed the cross-project resume hint failing in default Windows PowerShell 5.1 — Windows now uses ; as the command separator
•Fixed voice push-to-talk not working in the agent view's reply pane
•Fixed task lists rendering in random order when several tasks are created at once
•Fixed stale "Failed to install Anthropic marketplace" banner showing when the marketplace is already installed
•Fixed the PR badge in the footer not updating immediately after gh pr create and other PR-state-changing commands run in-session
•Fixed Agent Teams teammates with non-ASCII names failing every API call due to invalid header encoding
•Fixed /review using a deprecated projectCards GraphQL query that errored on repos with Classic Projects
•Fixed claude plugin validate not flagging skills: entries that point at a file instead of a directory — the error now suggests the parent directory
•Fixed an infinite loop where a skill using context: fork could repeatedly re-invoke itself instead of running
•Improved the Read tool to return a truncated first page with a "PARTIAL view" notice instead of a hard error when a whole-file read exceeds the token limit

v2.1.144

Claude Code 2.1.144

May 19, 2026

•Added /resume support for background sessions — sessions started via claude --bg or agent view now appear alongside interactive ones, marked with bg
•Added elapsed duration to background subagent completion notifications (e.g. "Agent completed · 3h 2m 5s")
•The /plugin browse and discover panes now show when a plugin was last updated
•/model now changes the model for the current session only; press d in the model picker to set a default for new sessions
•Renamed "extra usage" to "usage credits" across CLI copy; /extra-usage is now /usage-credits (old name still works)
•Fixed startup hanging up to 75s when api.anthropic.com is unreachable (captive portal, firewall, VPN issues) — side-channel API calls now time out after 15s
•Fixed garbled terminal output after a missed window-resize event (e.g. dragging a VS Code split-pane divider) — now self-heals on the next frame instead of requiring Ctrl+L
•Fixed progressive terminal display corruption (stale/garbled glyphs) that could appear in very long sessions and only cleared on terminal resize or restart
•Reduced terminal rendering glitches in VS Code by reducing spinner animation color count
•Fixed macOS background sessions crashing with "exit 1 before init" when the project lives under a Full Disk Access-protected folder (regression in 2.1.143)
•Fixed an unrecoverable conversation when reading a file whose image extension doesn't match its contents (e.g. HTML saved as .png) — now falls back to text
•Fewer spurious tool errors during search: head/tail file views now satisfy the read-before-edit check, and a "no matches" result (exit code 1) from egrep, fgrep, git grep, or git diff is no longer reported as a command failure
•Fixed /branch failing with "No conversation to branch" after entering a worktree or in some background sessions
•Fixed pressing Escape in the AskUserQuestion notes field aborting the turn instead of returning to answer selection
•Fixed model selection not applying when changed via the IDE model picker or applyFlagSettings after startup
•Resumed sessions now keep the model they were using instead of picking up another session's /model choice
•Fixed Bedrock and Vertex users unable to select "Opus (1M context)" from the /model picker (regression in v2.1.129)
•Fixed remote-session login failing with "Can't access this organization" for users with forceLoginMethod and forceLoginOrgUUID set
•Fixed MCP servers with paginated tools/list responses only returning the first page, silently dropping tools
•Fixed MCP images with unsupported MIME types (e.g. SVG) breaking the conversation — now saved to disk and referenced in the tool result
•Fixed file descriptor exhaustion when a build runs inside a skill directory — non-.md files no longer trigger skill reloads
•Fixed session title being generated from plugin monitor output instead of the user's first prompt
•Fixed Skill tool failing with permission error in headless mode (regression in v2.1.141)
•Fixed plugins enabled in your own settings showing "not cached" errors after first load on a fresh machine; plugins enabled only by a project's .claude/settings.json now show an actionable claude plugin install hint
•Fixed claude mcp list silently reporting no servers when .mcp.json can't be parsed (e.g. using VS Code's "servers" key instead of "mcpServers") — now shows configuration errors
•Fixed background side-queries on custom ANTHROPIC_BASE_URL setups and Bedrock Mantle not using Haiku — now falls back correctly when a first-party API key is configured or no Haiku model is set
•Fixed scrolling in attached background sessions on Windows — PgUp/PgDn, mouse wheel, and Ctrl+O transcript navigation now work
•Fixed a crash when closing the terminal while attached to a background session
•Fixed on Windows, pressing ← in claude agents leaving the list unresponsive to keyboard input
•Fixed ghost characters at the left edge when switching panes in Agent View on Windows Terminal with CJK content
•/bg and ←-detach now preserve directories added via /add-dir
•Fixed Edit/Write refusing with "background session hasn't isolated its changes yet" right after detaching a session that was already editing in place
•Fixed claude respawn <id> on a stopped background session showing "stopped" instead of running
•Fixed /resume picker not showing sessions forked from a background session
•Fixed opening a session from claude agents or running claude logs <id> hanging when the background service is unresponsive — now times out after 10s with a recovery hint
•Fixed background Bash tasks spawned by subagents staying "Running" in SDK task panels after the process exits
•Fixed completed or stopped background sessions briefly failing to wake being permanently marked as a startup crash
•Fixed markdown links in claude agents attached sessions rendering as plain text instead of clickable hyperlinks
•Fixed custom spinnerVerbs applying to the post-turn duration message — past-tense built-ins like "Worked for 5s" are restored there
•claude agents / --bg rejection messages now name the specific gate (non-TTY, env var, or setting) instead of a generic message
•claude --bg --name <label> now echoes the name in the post-spawn confirmation
•claude agents: renaming a background session with Ctrl+R now updates the attached session's banner immediately
•Background session worktree isolation guard now applies for non-git VCS users with WorktreeCreate hooks configured
•Plugin marketplace add/update now respects CLAUDE_CODE_PLUGIN_PREFER_HTTPS
•/plugin now returns to the Installed list after enabling, disabling, or uninstalling a plugin
•/doctor now shows an exec-form example when a command hook is missing the command field
•Skill-listing truncation is no longer shown as a startup notification — run /doctor for the full breakdown
•Improved recovery from rare pre-response stream stalls — now retries streaming once instead of falling back to a slower non-streaming request
•Improved SDK/headless MCP startup: pre-wait now overlaps startup instead of blocking before the first turn (up to 2s faster with slow MCP servers)
•The post-survey follow-up hint now appears after every non-dismiss survey response with context-aware copy, making it easier to share more detail via /feedback.

v2.1.143

Claude Code 2.1.143

May 15, 2026

•Added plugin dependency enforcement: claude plugin disable now refuses when another enabled plugin depends on the target (with a copy-pasteable disable-chain hint), and claude plugin enable force-enables transitive dependencies
•Added projected context cost (per-turn and per-invocation token estimates) to the /plugin marketplace browse pane
•Added worktree.bgIsolation: "none" setting to let background sessions edit the working copy directly without EnterWorktree, for repos where worktrees are impractical
•PowerShell tool now passes -ExecutionPolicy Bypass. Opt out with CLAUDE_CODE_POWERSHELL_RESPECT_EXECUTION_POLICY=1
•Background sessions now preserve the model and effort level you set after waking from idle
•Shift+Tab in attached agent sessions now includes auto mode in the cycle
•Fixed a corrupt .credentials.json with a non-array scopes value hanging the CLI on startup or silently aborting OAuth token refresh
•Fixed right-click paste in claude agents on Windows Terminal and WSL
•Fixed stop hooks that block repeatedly looping forever — the turn now ends with a warning after 8 consecutive blocks (override via CLAUDE_CODE_STOP_HOOK_BLOCK_CAP)
•Fixed Esc/Ctrl+C not cancelling a pending /loop wakeup while Claude is idle between iterations
•Fixed /goal evaluator firing while background shells or delegated subagents are still running
•Fixed NO_COLOR/FORCE_COLOR in settings.json env stripping Claude Code's own UI colors — they now apply to subprocesses only
•Fixed agent view spawning repeated PowerShell processes on Windows when listing sessions
•Fixed /bg without a prompt sending "continue" to the forked session — the fork now waits for input
•Fixed --agent <name> not finding plugin-contributed agents without the plugin: prefix
•Fixed deleting a session from agent view not removing its transcript file
•Fixed stale-fragment rendering when scrolling in attached background sessions on Windows Terminal
•Fixed background agents false-positive worker-stall detection storm after host sleep or macOS App Nap
•Fixed 5xx error messages pointing at status.claude.com instead of naming the configured gateway or cloud provider
•The PowerShell tool is now enabled by default on Windows for Bedrock, Vertex, and Foundry users. Opt out with CLAUDE_CODE_USE_POWERSHELL_TOOL=0.
•claude agents now accepts --add-dir, --settings, --mcp-config, and --plugin-dir and applies them to the dashboard and to background sessions dispatched from it
•claude agents accepts --permission-mode, --model, --effort, and --dangerously-skip-permissions to set defaults for sessions dispatched from the view
•claude --bg --dangerously-skip-permissions now persists across retire→wake
•Fixed background sessions silently capturing IDE file references into the warm spare's input, which caused the reference to be prepended to the next prompt dispatched from claude agents
•Worktree cleanup no longer falls back to rm -rf when git worktree remove fails, preventing loss of gitignored or in-progress files
•Fixed background-job sessions on macOS getting "Operation not permitted" errors when reading files under ~/Documents, ~/Desktop, or ~/Downloads, even with Full Disk Access granted.
•/bg now preserves --mcp-config, --settings, --add-dir, --plugin-dir, and --strict-mcp-config, so backgrounded sessions keep their MCP servers and settings across respawn.
•Background sessions launched from claude agents now honor permissions.defaultMode from settings.json (was previously overridden to auto mode)
•Fixed: on Windows, pressing ← in claude agents while a response was streaming could leave the agents list unresponsive to all input
•/bg and ←-detach now preserve --fallback-model, so backgrounded workers degrade to the fallback model on overload instead of hard-failing.
•/bg and ←-detach now preserve --allow-dangerously-skip-permissions, so the forked worker keeps bypass-permissions available in its Shift+Tab cycle.
•Fixed: background daemon spawn now falls back to the running binary when the ~/.local/bin/claude launcher is missing or non-executable
•Fixed claude agents --allow-dangerously-skip-permissions defaulting dispatched sessions to bypass mode instead of making it available in the permission cycle

v2.1.142

Claude Code 2.1.142

May 14, 2026

•Added new claude agents flags: --add-dir, --settings, --mcp-config, --plugin-dir, --permission-mode, --model, --effort, and --dangerously-skip-permissions to configure dispatched background sessions

•The /plugin details pane and claude plugin details now show LSP servers a plugin provides
•/web-setup warns before replacing an existing GitHub App connection
•Fixed MCP_TOOL_TIMEOUT not raising the per-request fetch timeout for remote HTTP and SSE MCP servers, which capped tool calls at 60 seconds regardless of the configured value
•Fixed background sessions not recognizing pre-existing git worktrees, blocking Edit while EnterWorktree refused to create a duplicate
•Fixed background sessions disappearing and daemon reconnect failing after macOS sleep/wake — the daemon now detects clock jumps instead of treating them as elapsed idle time

•Fixed background agents crash-looping when the Claude-in-Chrome extension is connected without a shared tab
•Fixed clicking links in an attached claude agents session — the background worker's headless browser shim no longer applies while attached
•Fixed claude agents "v to open in editor" using the daemon's default editor instead of your shell's $EDITOR/$VISUAL

•Fixed claude --bg --dangerously-skip-permissions not persisting across retire/wake
•Fixed session titles being derived from the URL when the first message is a link

•Fixed plugin cache cleanup deleting the active plugin version directory when no installation metadata is present
•Fixed /plugin browse pane showing "0 installs" for newly published plugins
•Fixed plugin advisories not naming every plugin.json key that shadows a default folder
•Improved reactive compaction: the first summarize attempt now seeds from the original request's overflow size, avoiding a wasted near-full-context retry
•Improved hook configuration error: configuring a prompt- or agent-type hook for SessionStart/Setup/SubagentStart now shows a clear "use a command-type hook instead" error
•Removed stale /model claude-sonnet-4-20250514 suggestion from Usage Policy refusal messages

v2.1.141

Claude Code 2.1.141

May 13, 2026

•Fixed claude agents showing the agent-type list instead of the dashboard when launched through a wrapper that adds flags
•Fixed claude agents opening a crashed session firing redundant dispatches when the working directory was deleted
•Fixed background jobs on a custom ANTHROPIC_BASE_URL gateway not getting auto-named — the namer now uses the main model when no Haiku model is configured
•Fixed /model in one session silently changing the autocompact threshold in other concurrent sessions
•Fixed switching permission mode while a tool-permission prompt is open not auto-dismissing the prompt when the new setting permits the tool
•Fixed pressing Enter while a permission/dialog prompt is open also submitting text in the input box

•Fixed Windows Alt+V image paste reporting "no image found" when the clipboard contains a screenshot
•Fixed SDK "Claude Code native binary not found" on Linux when both glibc and musl platform packages are installed

v2.1.140

Claude Code 2.1.140

May 6, 2026

•Added CLAUDE_CODE_SESSION_ID environment variable to the Bash tool subprocess environment, matching the session_id passed to hooks

•Subprocesses (Bash, hooks, MCP, LSP) no longer inherit OTEL_* environment variables, so OTEL-instrumented apps run via the Bash tool no longer pick up the CLI's own OTLP endpoint
•MCP: workspace is now a reserved server name — existing servers with that name will be skipped with a warning
•Reconnecting MCP servers no longer flood the conversation with full tool-name lists on every reconnect — re-announced tools are summarized by server prefix
•SDK hosts now receive a persistent localSettings suggestion for Bash permission prompts, so "Always allow" writes to .claude/settings.local.json
•EnterWorktree now creates the new branch from local HEAD as documented, instead of origin/<default-branch> — unpushed commits are no longer dropped

•Fixed focus mode briefly dimming the previous response when submitting a new prompt
•Fixed stray "4;0;" desktop notification on every /exit in Kitty and other terminals that interpret OSC 9 as a notification
