Release Notes
- Added /powerup — interactive lessons teaching Claude Code features with animated demos - Added CLAUDECODEPLUGINKEEPMARKETPLACEONFAILURE 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 f
