Changelog

What's changed

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)
