Fixed issue with submitting messages during extended thinking interrupting the thinking phase. Fixed API error when aborting mid-stream with whitespace text and thinking blocks. Fixed API proxy compatibility where 404 errors on streaming endpoints no longer trigger non-streaming fallback. Fixed proxy settings from settings.json not applying to WebFetch/HTTP requests on Node.js. Fixed /resume session picker showing raw XML instead of clean titles. Improved error messages for API connection failures showing specific causes. Surfaced errors from invalid managed settings. Added VSCode remote sessions and OAuth resume support with git branch/message count. Fixed scroll-to-bottom under-scrolling on VSCode session load/switch.

• Improved memory usage by trimming agent task message history after tasks complete

• Fixed /resume silently dropping sessions when the first message exceeds 16KB or uses array-format content
• Added chat:newline keybinding action for configurable multi-line input
• Added added_dirs to the statusline JSON workspace section, exposing directories added via /add-dir to external scripts
• Fixed claude doctor misclassifying mise and asdf-managed installations as native installs
• Fixed zsh heredoc failing with "read-only file system" error in sandboxed commands
• Fixed agent progress indicator showing inflated tool use count

• Fixed tool_decision OTel telemetry event not being emitted in headless/SDK mode
• Fixed session name being lost after context compaction — renamed sessions now preserve their custom title through compaction
• Increased initial session count in resume picker from 10 to 50 for faster session discovery
• Windows: fixed worktree session matching when drive letter casing differs

• Fixed shell commands permanently failing after a command deletes its own working directory
• Fixed hooks (PreToolUse, PostToolUse) silently failing to execute on Windows by using Git Bash instead of cmd.exe
• Fixed LSP findReferences and other location-based operations returning results from gitignored files
• Moved config backup files from home directory root to ~/.claude/backups/ to reduce home directory clutter
• Fixed sessions with large first prompts (>16KB) disappearing from the /resume list
• Fixed shell functions with double-underscore prefixes not being preserved across shell sessions
• Fixed spinner showing "0 tokens" counter before any tokens have been received
