Key Features

Plugin Enhancements

• Added ${CLAUDE_PLUGIN_DATA} variable for plugin persistent state that survives plugin updates; /plugin uninstall now prompts before deleting stored data
• Added support for effort, maxTurns, and disallowedTools frontmatter options in plugin-shipped agents

Terminal & UX Improvements

• Response text now streams line-by-line as it's generated, improving readability
• Terminal notifications (iTerm2, Kitty, Ghostty popups and progress bars) now work correctly when running inside tmux with set -g allow-passthrough on
• Fixed ctrl+u in normal mode to properly perform readline kill-line (half-page scroll moved to transcript mode only)

Security & Permissions

• Security fix: Fixed silent sandbox disable when dependencies are missing — now shows a visible startup warning
• Fixed deny: ["mcp__servername"] permission rules not removing MCP server tools before sending to model
• Fixed .git, .claude, and other protected directories being writable without prompt in bypassPermissions mode

Major Bug Fixes

Stability & Performance

• Fixed cc log and --resume silently truncating conversation history on large sessions (>5 MB) that used subagents

• Improved memory usage and startup time when resuming large sessions

Development Workflows

• Fixed git log HEAD failing with "ambiguous argument" inside sandboxed Bash on Linux

• Fixed Bash tool not finding Homebrew and PATH-dependent binaries when VS Code is launched from Dock/Spotlight

Voice & Input

• Fixed voice mode not working on WSL2 with WSLg (Windows 11)
• Fixed voice mode modifier-combo push-to-talk keybindings requiring a hold instead of activating immediately
• Fixed Backspace and Delete keys not working in vim NORMAL mode

Additional Fixes
