Added PowerShell tool for Windows as an opt-in preview. Learn more at https://code.claude.com/docs/en/tools-reference#powershell-tool
AddedANTHROPIC_DEFAULT_{OPUS,SONNET,HAIKU}_MODEL_SUPPORTS env vars to override effort/thinking capability detection for pinned default models for 3p (Bedrock, Vertex, Foundry), and `_MODEL_NAME`/`_DESCRIPTION` to customize the `/model` picker label
AddedCLAUDE_STREAM_IDLE_TIMEOUT_MS env var to configure the streaming idle watchdog threshold (default 90s)
AddedTaskCreated hook that fires when a task is created via `TaskCreate`
AddedWorktreeCreate hook support for `type: "http"` — return the created worktree path via `hookSpecificOutput.worktreePath` in the response JSON
AddedallowedChannelPlugins managed setting for team/enterprise admins to define a channel plugin allowlist
Addedx-client-request-id header to API requests for debugging timeouts
Added idle-return prompt that nudges users returning after 75+ minutes to `/clear`, reducing unnecessary token re-caching on stale sessions
VSCodeAdded rate limit warning banner with usage percentage and reset time
~changed 10
Deep links (claude-cli://) now open in your preferred terminal instead of whichever terminal happens to be first in the detection list
Rules and skills paths: frontmatter now accepts a YAML list of globs
MCP tool descriptions and server instructions are now capped at 2KB to prevent OpenAPI-generated servers from bloating context
MCP servers configured both locally and via claude.ai connectors are now deduplicated — the local config wins
Background bash tasks that appear stuck on an interactive prompt now surface a notification after ~45 seconds
Token counts ≥1M now display as "1.5m" instead of "1512.6k"
Global system-prompt caching now works when `ToolSearch` is enabled, including for users with MCP tools configured
Changed issue/PR references to only become clickable links when written as `owner/repo#123` — bare `#123` is no longer auto-linked
Slash commands unavailable for the current auth setup (`/voice`, `/mobile`, `/chrome`, `/upgrade`, etc.) are now hidden instead of shown
Stats screenshot (Ctrl+S in /stats) now works in all builds and is 16× faster
↑improved 7
Improved detection for dangerous removals of Windows drive roots (`C:\`, `C:\Windows`, etc.)
Improved interactive startup by ~30ms by running `setup()` in parallel with slash command and agent loading
Improved startup for claude "prompt" with MCP servers — the REPL now renders immediately instead of blocking until all servers connect
ImprovedRemote Control to show a specific reason when blocked instead of a generic "not yet enabled" message
Improved p90 prompt cache rate
Reduced scroll-to-top resets in long sessions by making the message window immune to compaction and grouping changes
Reduced terminal flickering when animated tool progress scrolls above the viewport
✓fixed 14
Fixedvoice push-to-talk: holding the voice key no longer leaks characters into the text input, and transcripts now insert at the correct position
Fixed up/down arrow keys being unresponsive when a footer item is focused
FixedCtrl+U (kill-to-line-start) being a no-op at line boundaries in multiline input, so repeated `Ctrl+U` now clears across lines
Fixed null-unbinding a default chord binding (e.g. `"ctrl+x ctrl+k": null`) still entering chord-wait mode instead of freeing the prefix key
Fixed mouse events inserting literal "mouse" text into transcript search input
Fixed workflow subagents failing with API 400 when the outer session uses `--json-schema` and the subagent also specifies a schema
Fixed missing background color behind certain emoji in user message bubbles on some terminals
Fixed a hang when generating attachment snippets for large edited files
Fixed MCP tool/resource cache leak on server reconnect
Fixed a startup performance issue where partial clone repositories (Scalar/GVFS) triggered mass blob downloads
Fixed native terminal cursor not tracking the text input caret, so IME composition (CJK input) now renders inline and screen readers can follow the input position
Fixed spurious "Not logged in" errors on macOS caused by transient keychain read failures
Fixed cold-start race where core tools could be deferred without their bypass active, causing Edit/Write to fail with InputValidationError on typed parameters
