What's changed

  • Added PowerShell tool for Windows as an opt-in preview. Learn more at https://code.claude.com/docs/en/tools-reference#powershell-tool
  • Added ANTHROPIC_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
  • Added CLAUDE_STREAM_IDLE_TIMEOUT_MS env var to configure the streaming idle watchdog threshold (default 90s)
  • Added TaskCreated hook that fires when a task is created via TaskCreate
  • Added WorktreeCreate hook support for type: "http" — return the created worktree path via hookSpecificOutput.worktreePath in the response JSON
  • Added allowedChannelPlugins managed setting for team/enterprise admins to define a channel plugin allowlist
  • Added x-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
  • 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
  • Fixed voice 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
  • Fixed Ctrl+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 the "allow Claude to edit its own settings for this session" permission option not sticking for users with Edit(.claude) allow rules
  • 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
  • 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
  • Improved Remote 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
  • 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
  • [VSCode] Added rate limit warning banner with usage percentage and reset time
  • Stats screenshot (Ctrl+S in /stats) now works in all builds and is 16× faster
