Claude Code v2.1.91

构建日期: 2026-04-02T22:04:30Z

最新更新

2.1.91

  • Added MCP tool result persistence override via _meta["anthropic/maxResultSizeChars"] annotation (up to 500K), allowing larger results like DB schemas to pass through without truncation
  • Added disableSkillShellExecution setting to disable inline shell execution in skills, custom slash commands, and plugin commands
  • Added support for multi-line prompts in claude-cli://open?q= deep links (encoded newlines %0A no longer rejected)
  • Plugins can now ship executables under bin/ and invoke them as bare commands from the Bash tool
  • Fixed transcript chain breaks on --resume that could lose conversation history when async transcript writes fail silently
  • Fixed cmd+delete not deleting to start of line on iTerm2, kitty, WezTerm, Ghostty, and Windows Terminal
  • Fixed plan mode in remote sessions losing track of the plan file after a container restart, which caused permission prompts on plan edits and an empty plan-approval modal
  • Fixed JSON schema validation for permissions.defaultMode: "auto" in settings.json
  • Fixed Windows version cleanup not protecting the active version's rollback copy
  • /feedback now explains why it's unavailable instead of disappearing from the slash menu
  • Improved /claude-api skill guidance for agent design patterns including tool surface decisions, context management, and caching strategy
  • Improved performance: faster stripAnsi on Bun by routing through Bun.stripANSI
  • Edit tool now uses shorter old_string anchors, reducing output tokens

2.1.90

  • Added /powerup — interactive lessons teaching Claude Code features with animated demos
  • Added CLAUDE_CODE_PLUGIN_KEEP_MARKETPLACE_ON_FAILURE env var to keep the existing marketplace cache when git pull fails, useful in offline environments
  • Added .husky to protected directories (acceptEdits mode)
  • Fixed an infinite loop where the rate-limit options dialog would repeatedly auto-open after hitting your usage limit, eventually crashing the session
  • Fixed --resume causing a full prompt-cache miss on the first request for users with deferred tools, MCP servers, or custom agents (regression since v2.1.69)
  • Fixed Edit/Write failing with "File content has changed" when a PostToolUse format-on-save hook rewrites the file between consecutive edits
  • Fixed PreToolUse hooks that emit JSON to stdout and exit with code 2 not correctly blocking the tool call
  • Fixed collapsed search/read summary badge appearing multiple times in fullscreen scrollback when a CLAUDE.md file auto-loads during a tool call
  • Fixed auto mode not respecting explicit user boundaries ("don't push", "wait for X before Y") even when the action would otherwise be allowed
  • Fixed click-to-expand hover text being nearly invisible on light terminal themes
  • Fixed UI crash when malformed tool input reached the permission dialog
  • Fixed headers disappearing when scrolling /model, /config, and other selection screens
  • Hardened PowerShell tool permission checks: fixed trailing & background job bypass, -ErrorAction Break debugger hang, archive-extraction TOCTOU, and parse-fail fallback deny-rule degradation
  • Improved performance: eliminated per-turn JSON.stringify of MCP tool schemas on cache-key lookup
  • Improved performance: SSE transport now handles large streamed frames in linear time (was quadratic)
  • Improved performance: SDK sessions with long conversations no longer slow down quadratically on transcript writes
  • Improved /resume all-projects view to load project sessions in parallel, improving load times for users with many projects
  • Changed --resume picker to no longer show sessions created by claude -p or SDK invocations
  • Removed Get-DnsClientCache and ipconfig /displaydns from auto-allow (DNS cache privacy)

2.1.89

  • Added "defer" permission decision to PreToolUse hooks — headless sessions can pause at a tool call and resume with -p --resume to have the hook re-evaluate
  • Added CLAUDE_CODE_NO_FLICKER=1 environment variable to opt into flicker-free alt-screen rendering with virtualized scrollback
  • Added PermissionDenied hook that fires after auto mode classifier denials — return {retry: true} to tell the model it can retry
  • Added named subagents to @ mention typeahead suggestions
  • Added MCP_CONNECTION_NONBLOCKING=true for -p mode to skip the MCP connection wait entirely, and bounded --mcp-config server connections at 5s instead of blocking on the slowest server
  • Auto mode: denied commands now show a notification and appear in /permissions → Recent tab where you can retry with r
  • Fixed Edit(//path/**) and Read(//path/**) allow rules to check the resolved symlink target, not just the requested path
  • Fixed voice push-to-talk not activating for some modifier-combo bindings, and voice mode on Windows failing with "WebSocket upgrade rejected with HTTP 101"
  • Fixed Edit/Write tools doubling CRLF on Windows and stripping Markdown hard line breaks (two trailing spaces)
  • Fixed StructuredOutput schema cache bug causing ~50% failure rate when using multiple schemas
  • Fixed memory leak where large JSON inputs were retained as LRU cache keys in long-running sessions
  • Fixed a crash when removing a message from very large session files (over 50MB)
  • Fixed LSP server zombie state after crash — server now restarts on next request instead of failing until session restart
  • Fixed prompt history entries containing CJK or emoji being silently dropped when they fall on a 4KB boundary in ~/.claude/history.jsonl
  • Fixed /stats undercounting tokens by excluding subagent usage, and losing historical data beyond 30 days when the stats cache format changes
  • Fixed -p --resume hangs when the deferred tool input exceeds 64KB or no deferred marker exists, and -p --continue not resuming deferred tools
  • Fixed claude-cli:// deep links not opening on macOS
  • Fixed MCP tool errors truncating to only the first content block when the server returns multi-element error content
  • Fixed skill reminders and other system context being dropped when sending messages with images via the SDK
  • Fixed PreToolUse/PostToolUse hooks to receive file_path as an absolute path for Write/Edit/Read tools, matching the documented behavior
  • Fixed autocompact thrash loop — now detects when context refills to the limit immediately after compacting three times in a row and stops with an actionable error instead of burning API calls
  • Fixed prompt cache misses in long sessions caused by tool schema bytes changing mid-session
  • Fixed nested CLAUDE.md files being re-injected dozens of times in long sessions that read many files
  • Fixed --resume crash when transcript contains a tool result from an older CLI version or interrupted write
  • Fixed misleading "Rate limit reached" message when the API returned an entitlement error — now shows the actual error with actionable hints
  • Fixed hooks if condition filtering not matching compound commands (ls && git push) or commands with env-var prefixes (FOO=bar git push)
  • Fixed collapsed search/read group badges duplicating in terminal scrollback during heavy parallel tool use
  • Fixed notification invalidates not clearing the currently-displayed notification immediately
  • Fixed prompt briefly disappearing after submit when background messages arrived during processing
  • Fixed Devanagari and other combining-mark text being truncated in assistant output
  • Fixed rendering artifacts on main-screen terminals after layout shifts
  • Fixed voice mode failing to request microphone permission on macOS Apple Silicon
  • Fixed Shift+Enter submitting instead of inserting a newline on Windows Terminal Preview 1.25
  • Fixed periodic UI jitter during streaming in iTerm2 when running inside tmux
  • Fixed PowerShell tool incorrectly reporting failures when commands like git push wrote progress to stderr on Windows PowerShell 5.1
  • Fixed a potential out-of-memory crash when the Edit tool was used on very large files (>1 GiB)
  • Improved collapsed tool summary to show "Listed N directories" for ls/tree/du instead of "Read N files"
  • Improved Bash tool to warn when a formatter/linter command modifies files you have previously read, preventing stale-edit errors
  • Improved @-mention typeahead to rank source files above MCP resources with similar names
  • Improved PowerShell tool prompt with version-appropriate syntax guidance (5.1 vs 7+)
  • Changed Edit to work on files viewed via Bash with sed -n or cat, without requiring a separate Read call first
  • Changed hook output over 50K characters to be saved to disk with a file path + preview instead of being injected directly into context
  • Changed cleanupPeriodDays: 0 in settings.json to be rejected with a validation error — it previously silently disabled transcript persistence
  • Changed thinking summaries to no longer be generated by default in interactive sessions — set showThinkingSummaries: true in settings.json to restore
  • Documented TaskCreated hook event and its blocking behavior
  • Preserved task notifications when backgrounding a running command with Ctrl+B
  • PowerShell tool on Windows: external-command arguments containing both a double-quote and whitespace now prompt instead of auto-allowing (PS 5.1 argument-splitting hardening)
  • /env now applies to PowerShell tool commands (previously only affected Bash)
  • /usage now hides redundant "Current week (Sonnet only)" bar for Pro and Enterprise plans
  • Image paste no longer inserts a trailing space
  • Pasting !command into an empty prompt now enters bash mode, matching typed ! behavior
  • /buddy is here for April 1st — hatch a small creature that watches you code
