9<Update label="2.1.236" description="August 19, 2026">
10 * Added `ANTHROPIC_DEFAULT_MODEL` environment variable: sets the model new sessions start on, while a `/model` pick still overrides it and persists across restarts (unlike `ANTHROPIC_MODEL`)
11 * Added `notify_when_idle` to cross-session `SendMessage`: ask another Claude Code session on this machine to send one notice when it next goes idle — opt-in, one-shot, no polling (macOS and Linux)
12 * Sandbox: on macOS, wildcard read-deny rules (e.g. `**/.env`) now take precedence inside allowed read regions, cover matched directories' contents, and can't be bypassed by renaming the denied file
13 * Fixed clipboard copy, background housekeeping, background sessions, and local MCP logs breaking after the directory a session had switched into was removed (since 2.1.229)
14 * Fixed the fullscreen renderer failing permanently after a single failed start: it now falls back to the classic renderer instead of exiting on every subsequent launch
15 * Fixed the `/model` picker rendering taller than the terminal: it now shows only as many models as fit the window, with the rest reachable by scrolling
16 * Fixed `SendMessage` calls being rejected when a malformed closing tag left the message text inside the summary field
17 * Fixed unhandled promise rejections when a subprocess fails to start, for example `powershell.exe` on WSL with Windows interop disabled (regression in 2.1.234)
18 * Fixed fullscreen mode sometimes not showing a newly sent message until the next update after the terminal was resized
19 * Fixed a blank band that could remain above the prompt after clearing a multi-line prompt, and panes not repainting after resizing the terminal away and back, in fullscreen mode
20 * Fixed the managed-settings approval prompt sometimes not appearing at startup while still capturing the first keypress as approval
21 * Fixed terminal tab titles jumping in tmux (iTerm tmux integration): the title is now written only when its text changes instead of animating every 960ms
22 * Fixed an unclear error when the cloud environments list came back empty or malformed
23 * Fixed the Fable 5 first-time usage-credits prompt auto-selecting the fallback model after 60 seconds with no answer when using Remote Control
24 * Fixed spinner tips never appearing, with a repeated background error, when the cached guest-pass reward in `~/.claude.json` was malformed
25 * Fixed skills hot-reload in SDK/VS Code sessions raising an error on every skills change after the session's working directory was deleted (2.1.229+)
26 * Fixed self-hosted runner sessions released on idle, retire, or startup timeout occasionally resuming on another runner before the post-session hook had finished
27 * Fixed the Clawd mascot's eyes and feet rendering unevenly in iTerm2 at some font sizes
28 * Fixed occasional runaway session recaps: recap text (automatic and `/recap`) is now capped at 400 characters, cut at a word boundary
29 * Improved startup performance: the session counter is now written in the background
30 * Improved auto mode: `Monitor` allow rules are now set aside while auto mode is active, so Monitor commands are reviewed the same way Bash commands are
31 * Improved auto mode on Bedrock, Vertex AI, and Foundry, and when telemetry is disabled: the classifier now uses the same defaults as on the Claude API, including severity-scored classification
32 * Improved auto mode: the git status check can no longer be fooled by a repo's `status.showUntrackedFiles=no` setting into reporting a clean tree
33 * 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
34 * `/goal`: an idle session whose goal is parked behind long-running background work now checks in automatically after 30 minutes (then 1h, 2h) instead of waiting for you to return
35 * `/usage` now shows the usage-credits spend row for Team and Enterprise members, and shows a capped row at 0% before anything is spent
36 * SIGTERM in print/SDK mode no longer records an interrupted turn or synthetic tool denials before exiting; running commands are still terminated and the process still exits with code 143
37 * Pressing Enter on a slash-command typo or a command unavailable in this session now reports it instead of running the closest fuzzy match; prefixes and aliases still run
38 * Remote Control now marks a session offline within seconds when the CLI exits or its terminal closes
39 * `SendMessage` now refuses further messages to a session up front once a rapid burst would exceed what that session's inbox accepts, instead of reporting them sent while they were dropped
40 * Aligned the session title chip on the prompt border with the footer's right edge
41 * Right-aligned footer items (goal indicator, session state, background agent status) and truncated notices now share a consistent right margin with the rest of the prompt area
42 * \[VSCode] Added screen reader support for the transcript: live announcements for replies, permission requests, errors, and status changes, plus per-turn heading navigation

1046 * Added an optional `spellcheck` setting that underlines misspelled words in the prompt input as you type, using your installed `aspell`, `hunspell`, or `ispell`
1147 * Fixed whole-prompt-cache invalidation when a language server disconnected or reconnected mid-session

2137<Update label="2.1.129" description="May 6, 2026">
2138 * Added `--plugin-url <url>` flag to fetch a plugin `.zip` archive from a URL for the current session
2139 * Added `CLAUDE_CODE_FORCE_SYNC_OUTPUT=1` env var to force-enable synchronized output on terminals that auto-detection misses (e.g. Emacs `eat`)
2140 * Added `CLAUDE_CODE_PACKAGE_MANAGER_AUTO_UPDATE`: when set on Homebrew or WinGet installations, Claude Code runs the upgrade command in the background and prompts to restart
2141 * Plugin manifests: `themes` and `monitors` should now be declared under `"experimental": { ... }`. Top-level declarations still work but `claude plugin validate` will warn
2142 * Gateway `/v1/models` discovery for the `/model` picker is now opt-in via `CLAUDE_CODE_ENABLE_GATEWAY_MODEL_DISCOVERY=1` (was automatic in 2.1.126–2.1.128)
2143 * Ctrl+R history picker now defaults to searching all prompts across all projects, matching pre-2.1.124 behavior. Press Ctrl+S to narrow to the current project or session
2144 * Third-party deployments (Bedrock, Vertex, Foundry, or `ANTHROPIC_BASE_URL` gateway) no longer see spinner tips pointing at first-party Anthropic surfaces
2145 * `skillOverrides` setting now works: `off` hides from model and `/`, `user-invocable-only` hides from model only, `name-only` collapses description
2146 * The `claude_code.pull_request.count` OTel metric now counts PRs/MRs created via MCP tools, not just shell commands
2147 * Policy refusal error messages now include the API Request ID for easier support debugging
2148 * Fixed API errors with unrecognized 400 status codes showing raw JSON instead of the underlying error message
2149 * Fixed `/clear` not resetting the terminal tab title after a conversation
2150 * Fixed session title chip from `/rename` disappearing while a permission or other dialog is active
2151 * Fixed agent panel below the prompt being hidden when subagents are running (regression in 2.1.122)
2152 * Fixed external-editor handoff (Ctrl+G) blanking the conversation history above the prompt
2153 * Fixed `/context` dumping its rendered ASCII visualization grid into the conversation, wasting \~1.6k tokens per call
2154 * Fixed `/agents` Library list arrow-key navigation: the highlighted agent now stays visible when the list exceeds the viewport
2155 * Fixed `/branch` success message not including the new branch's session id for `/resume`
2156 * Fixed bold headers with keycap/ZWJ/skin-tone emoji losing trailing characters in fullscreen mode
2157 * Fixed server-managed settings policy not applying for enterprise/team users whose stored OAuth credentials lacked the `user:inference` scope
2158 * Fixed OAuth refresh race after wake-from-sleep that could log out all running sessions
2159 * Fixed 1-hour prompt cache TTL being silently downgraded to 5 minutes
2160 * Fixed cache-miss warning appearing spuriously after `/clear` or compaction when changing `/effort` or `/model`
2161 * Fixed `Bash(mkdir *)`, `Bash(touch *)` and similar allow rules not being honored for in-project paths
2162 * Fixed `deniedMcpServers` patterns with a `*://` scheme wildcard not matching mixed-case hostnames
2163 * Fixed harmless WebSocket warning being logged as an error in `--debug` during voice mode
2164 * \[VSCode] Fixed `/clear` not clearing the conversation context and displayed transcript

2167<Update label="2.1.128" description="May 4, 2026">
2168 * Bare `/color` (no args) now picks a random session color
2169 * `/mcp` now shows the tool count for connected servers and flags servers that connected with 0 tools
2170 * `--plugin-dir` now accepts `.zip` plugin archives in addition to directories
2171 * `--channels` now works with console (API key) authentication — console orgs with managed settings must set `channelsEnabled: true` to enable
2172 * Updated `/model` picker: collapsed duplicate Opus 4.7 entries, and current Opus now shows as "Opus" instead of "Opus 4.7"
2173 * 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
2174 * MCP: `workspace` is now a reserved server name — existing servers with that name will be skipped with a warning
2175 * Reconnecting MCP servers no longer flood the conversation with full tool-name lists on every reconnect — re-announced tools are summarized by server prefix
2176 * SDK hosts now receive a persistent `localSettings` suggestion for Bash permission prompts, so "Always allow" writes to `.claude/settings.local.json`
2177 * `EnterWorktree` now creates the new branch from local HEAD as documented, instead of `origin/<default-branch>` — unpushed commits are no longer dropped
2178 * Auto mode: when the classifier can't evaluate an action, the error now includes a hint (retry, `/compact`, or run with `--debug`)
2179 * Fixed focus mode briefly dimming the previous response when submitting a new prompt
2180 * Fixed stray "4;0;" desktop notification on every `/exit` in Kitty and other terminals that interpret OSC 9 as a notification
2181 * Fixed Remote Control showing an empty "Opening your options…" message on rate limit instead of actionable upsell options
2182 * Fixed drag-and-drop image upl
