What's changed

  • Added CLAUDE_CODE_NO_FLICKER=1 environment variable to opt into flicker-free alt-screen rendering with virtualized scrollback
  • Added PermissionDenied hook that fires after auto mode classifier denials — return {retry: true} to tell the model it can retry
  • Added named subagents to @ mention typeahead suggestions
  • Fixed prompt cache misses in long sessions caused by tool schema bytes changing mid-session
  • Fixed nested CLAUDE.md files being re-injected dozens of times in long sessions that read many files
  • Fixed Edit/Write tools doubling CRLF on Windows and stripping Markdown hard line breaks (two trailing spaces)
  • Fixed StructuredOutput schema cache bug causing ~50% failure rate in workflows with multiple schemas
  • Fixed memory leak where large JSON inputs were retained as LRU cache keys in long-running sessions
  • Fixed a potential out-of-memory crash when the Edit tool was used on very large files (>1 GiB)
  • Fixed a crash when removing a message from very large session files (over 50MB)
  • Fixed --resume crash when transcript contains a tool result from an older CLI version or interrupted write
  • Fixed misleading "Rate limit reached" message when the API returned an entitlement error — now shows the actual error with actionable hints
  • Fixed LSP server zombie state after crash — server now restarts on next request instead of failing until session restart
  • Fixed hooks if condition filtering not matching compound commands (ls && git push) or commands with env-var prefixes (FOO=bar git push)
  • Fixed prompt history entries containing CJK or emoji being silently dropped when they fall on a 4KB boundary in ~/.claude/history.jsonl
  • Fixed /stats losing historical data beyond 30 days when the stats cache format changes
  • Fixed /stats undercounting tokens by excluding subagent/fork usage
  • Fixed scrollback disappearing when scrolling up in long sessions
  • Fixed collapsed search/read group badges duplicating in terminal scrollback during heavy parallel tool use
  • Fixed notification invalidates not clearing the currently-displayed notification immediately
  • Fixed prompt briefly disappearing after submit when background messages arrived during processing
  • Fixed long /btw responses being clipped with no way to scroll — responses now render in a scrollable viewport
  • Fixed Devanagari and other combining-mark text being truncated in assistant output
  • Fixed rendering artifacts on main-screen terminals after layout shifts
  • Fixed voice mode failing to request microphone permission on macOS Apple Silicon
  • Fixed voice push-to-talk not activating for some modifier-combo bindings
  • Fixed voice mode on Windows failing with "WebSocket upgrade rejected with HTTP 101"
  • Fixed Shift+Enter submitting instead of inserting a newline on Windows Terminal Preview 1.25
  • Fixed periodic UI jitter during streaming in iTerm2 when running inside tmux
  • Fixed PowerShell tool incorrectly reporting failures when commands like git push wrote progress to stderr on Windows PowerShell 5.1
  • Fixed SDK error result messages (error_during_execution, error_max_turns) to correctly set is_error: true with descriptive messages
  • Fixed task notifications being lost when backgrounding a session with Ctrl+B
  • Fixed PreToolUse/PostToolUse hooks not providing file_path as an absolute path for Write/Edit/Read tools
  • Improved PowerShell tool prompt with version-appropriate syntax guidance (5.1 vs 7+)
  • Thinking summaries are no longer generated by default in interactive sessions — set showThinkingSummaries: true in settings to restore
  • Auto mode denied commands now show a notification and appear in /permissions → Recent tab
  • /env now applies to PowerShell tool commands (previously only affected Bash)
  • /usage now hides redundant "Current week (Sonnet only)" bar for Pro and Enterprise plans
  • Collapsed tool summary now shows "Listed N directories" for ls/tree/du instead of "Read N files"
  • Image paste no longer inserts a trailing space
  • Pasting !command into an empty prompt now enters bash mode, matching typed ! behavior
