Claude Code 2.1.90 herunterladen

- 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)
