 ## 2.1.x Series (January-February 2026)
 
+### v2.1.47 (2026-02-19)
+
+- **Improved**: VS Code plan preview auto-updates as Claude iterates; commenting enabled only when plan is ready for review; preview stays open when rejected for revision
+- **New**: `ctrl+f` kills all background agents simultaneously (replaces double-ESC); ESC now cancels main thread only, background agents keep running
+- **New**: `last_assistant_message` field added to Stop and SubagentStop hook inputs (access final response without parsing transcript files)
+- **New**: `chat:newline` keybinding action; `added_dirs` in statusline JSON workspace section
+- **Fixed**: Compaction failing when conversation contains many PDF documents (strips document blocks alongside images)
+- **Fixed**: Edit tool corrupting Unicode curly quotes (`"` `"` `'` `'`) by replacing with straight quotes
+- **Fixed**: Parallel file write/edit — single file failure no longer aborts sibling operations
+- **Fixed**: OSC 8 hyperlinks only clickable on first line when link text wraps across multiple terminal lines
+- **Fixed**: Bash permission classifier now validates match descriptions against actual input rules (prevents hallucinated permissions)
+- **Fixed**: Config backups timestamped and rotated (5 most recent kept) instead of overwriting
+- **Fixed**: Session name lost after context compaction; plan mode lost after compaction
+- **Fixed**: Hooks (PreToolUse, PostToolUse) silently failing on Windows (now uses Git Bash)
+- **Fixed**: Custom agents/skills not discovered in git worktrees (main repo `.claude/` now included)
+- **Fixed**: 70+ additional rendering, session, permission, and platform fixes
+
+### v2.1.46 (2026-02-19)
+
+- **Fixed**: Orphaned Claude Code processes after terminal disconnect on macOS
+- **New**: Support for using claude.ai MCP connectors in Claude Code
+
 ### v2.1.45 (2026-02-17)
 
 - **New**: Claude Sonnet 4.6 model support
