Claude Code v2.1.86

构建日期: 2026-03-27T20:34:42Z

最新更新

2.1.86

  • Added X-Claude-Code-Session-Id header to API requests so proxies can aggregate requests by session without parsing the body
  • Added .jj and .sl to VCS directory exclusion lists so Grep and file autocomplete don't descend into Jujutsu or Sapling metadata
  • Fixed --resume failing with "tool_use ids were found without tool_result blocks" on sessions created before v2.1.85
  • Fixed Write/Edit/Read failing on files outside the project root (e.g., ~/.claude/CLAUDE.md) when conditional skills or rules are configured
  • Fixed unnecessary config disk writes on every skill invocation that could cause performance issues and config corruption on Windows
  • Fixed potential out-of-memory crash when using /feedback on very long sessions with large transcript files
  • Fixed --bare mode dropping MCP tools in interactive sessions and silently discarding messages enqueued mid-turn
  • Fixed the c shortcut copying only ~20 characters of the OAuth login URL instead of the full URL
  • Fixed masked input (e.g., OAuth code paste) leaking the start of the token when wrapping across multiple lines on narrow terminals
  • Fixed official marketplace plugin scripts failing with "Permission denied" on macOS/Linux since v2.1.83
  • Fixed statusline showing another session's model when running multiple Claude Code instances and using /model in one of them
  • Fixed scroll not following new messages after wheel scroll or click-to-select at the bottom of a long conversation
  • Fixed /plugin uninstall dialog: pressing n now correctly uninstalls the plugin while preserving its data directory
  • Fixed a regression where pressing Enter after clicking could leave the transcript blank until the response arrived
  • Fixed ultrathink hint lingering after deleting the keyword
  • Fixed memory growth in long sessions from markdown/highlight render caches retaining full content strings
  • Reduced startup event-loop stalls when many claude.ai MCP connectors are configured (macOS keychain cache extended from 5s to 30s)
  • Reduced token overhead when mentioning files with @ — raw string content no longer JSON-escaped
  • Improved prompt cache hit rate for Bedrock, Vertex, and Foundry users by removing dynamic content from tool descriptions
  • Memory filenames in the "Saved N memories" notice now highlight on hover and open on click
  • Skill descriptions in the /skills listing are now capped at 250 characters to reduce context usage
  • Changed /skills menu to sort alphabetically for easier scanning
  • Auto mode now shows "unavailable for your plan" when disabled by plan restrictions (was "temporarily unavailable")
  • [VSCode] Fixed extension incorrectly showing "Not responding" during long-running operations
  • [VSCode] Fixed extension defaulting Max plan users to Sonnet after the OAuth token refreshes (8 hours after login)
  • Read tool now uses compact line-number format and deduplicates unchanged re-reads, reducing token usage

2.1.85

  • Added CLAUDE_CODE_MCP_SERVER_NAME and CLAUDE_CODE_MCP_SERVER_URL environment variables to MCP headersHelper scripts, allowing one helper to serve multiple servers
  • Added conditional if field for hooks using permission rule syntax (e.g., Bash(git *)) to filter when they run, reducing process spawning overhead
  • Added timestamp markers in transcripts when scheduled tasks (/loop, CronCreate) fire
  • Added trailing space after [Image #N] placeholder when pasting images
  • Deep link queries (claude-cli://open?q=…) now support up to 5,000 characters, with a "scroll to review" warning for long pre-filled prompts
  • MCP OAuth now follows RFC 9728 Protected Resource Metadata discovery to find the authorization server
  • Plugins blocked by organization policy (managed-settings.json) can no longer be installed or enabled, and are hidden from marketplace views
  • PreToolUse hooks can now satisfy AskUserQuestion by returning updatedInput alongside permissionDecision: "allow", enabling headless integrations that collect answers via their own UI
  • tool_parameters in OpenTelemetry tool_result events are now gated behind OTEL_LOG_TOOL_DETAILS=1
  • Fixed /compact failing with "context exceeded" when the conversation has grown too large for the compact request itself to fit
  • Fixed /plugin enable and /plugin disable failing when a plugin's install location differs from where it's declared in settings
  • Fixed --worktree exiting with an error in non-git repositories before the WorktreeCreate hook could run
  • Fixed deniedMcpServers setting not blocking claude.ai MCP servers
  • Fixed switch_display in the computer-use tool returning "not available in this session" on multi-monitor setups
  • Fixed crash when OTEL_LOGS_EXPORTER, OTEL_METRICS_EXPORTER, or OTEL_TRACES_EXPORTER is set to none
  • Fixed diff syntax highlighting not working in non-native builds
  • Fixed MCP step-up authorization failing when a refresh token exists — servers requesting elevated scopes via 403 insufficient_scope now correctly trigger the re-authorization flow
  • Fixed memory leak in remote sessions when a streaming response is interrupted
  • Fixed persistent ECONNRESET errors during edge connection churn by using a fresh TCP connection on retry
  • Fixed prompts getting stuck in the queue after running certain slash commands, with up-arrow unable to retrieve them
  • Fixed Python Agent SDK: type:'sdk' MCP servers passed via --mcp-config are no longer dropped during startup
  • Fixed raw key sequences appearing in the prompt when running over SSH or in the VS Code integrated terminal
  • Fixed Remote Control session status staying stuck on "Requires Action" after a permission is resolved
  • Fixed shift+enter and meta+enter being intercepted by typeahead suggestions instead of inserting newlines
  • Fixed stale content bleeding through when scrolling up during streaming
  • Fixed terminal left in enhanced keyboard mode after exit in Ghostty, Kitty, WezTerm, and other terminals supporting the Kitty keyboard protocol — Ctrl+C and Ctrl+D now work correctly after quitting
  • Improved @-mention file autocomplete performance on large repositories
  • Improved PowerShell dangerous command detection
  • Improved scroll performance with large transcripts by replacing WASM yoga-layout with a pure TypeScript implementation
  • Reduced UI stutter when compaction triggers on large sessions

2.1.84

  • 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
