Claude Code 2.1.89: atsisiųsti Windows sistemai

- Added "defer" permission decision to PreToolUse hooks — headless sessions can pause at a tool call and resume with -p --resume to have the hook re-evaluate
- 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
- Added MCP_CONNECTION_NONBLOCKING=true for -p mode to skip the MCP connection wait entirely, and bounded --mcp-config server connections at 5s instead of blocking on the slowest server
- Auto mode: denied commands now show a notification and appear in /permissions → Recent tab where you can retry with r
- Fixed Edit(//path/**) and Read(//path/**) allow rules to check the resolved symlink target, not just the requested path
- Fixed voice push-to-talk not activating for some modifier-combo bindings, and voice mode on Windows failing with "WebSocket upgrade rejected with HTTP 101"
- 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 when using multiple schemas
- Fixed memory leak where large JSON inputs were retained as LRU cache keys in long-running sessions
- Fixed a crash when removing a message from very large session files (over 50MB)
- Fixed LSP server zombie state after crash — server now restarts on next request instead of failing until session restart
- Fixed prompt history entries containing CJK or emoji being silently dropped when they fall on a 4KB boundary in ~/.claude/history.jsonl
- Fixed /stats undercounting tokens by excluding subagent usage, and losing historical data beyond 30 days when the stats cache format changes
- Fixed -p --resume hangs when the deferred tool input exceeds 64KB or no deferred marker exists, and -p --continue not resuming deferred tools
- Fixed claude-cli:// deep links not opening on macOS
- Fixed MCP tool errors truncating to only the first content block when the server returns multi-element error content
- Fixed skill reminders and other system context being dropped when sending messages with images via the SDK
- Fixed PreToolUse/PostToolUse hooks to receive file_path as an absolute path for Write/Edit/Read tools, matching the documented behavior
- Fixed autocompact thrash loop — now detects when context refills to the limit immediately after compacting three times in a row and stops with an actionable error instead of burning API calls
- 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 --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 hooks if condition filtering not matching compound commands (ls && git push) or commands with env-var prefixes (FOO=bar git push)
- 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 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 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 a potential out-of-memory crash when the Edit tool was used on very large files (>1 GiB)
- Improved collapsed tool summary to show "Listed N directories" for ls/tree/du instead of "Read N files"
- Improved Bash tool to warn when a formatter/linter command modifies files you have previously read, preventing stale-edit errors
- Improved @-mention typeahead to rank source files above MCP resources with similar names
- Improved PowerShell tool prompt with version-appropriate syntax guidance (5.1 vs 7+)
- Changed Edit to work on files viewed via Bash with sed -n or cat, without requiring a separate Read call first
- Changed hook output over 50K characters to be saved to disk with a file path + preview instead of being injected directly into context
- Changed cleanupPeriodDays: 0 in settings.json to be rejected with a validation error — it previously silently disabled transcript persistence
- Changed thinking summaries to no longer be generated by default in interactive sessions — set showThinkingSummaries: true in settings.json to restore
- Documented TaskCreated hook event and its blocking behavior
- Preserved task notifications when backgrounding a running command with Ctrl+B
- PowerShell tool on Windows: external-command arguments containing both a double-quote and whitespace now prompt instead of auto-allowing (PS 5.1 argument-splitting hardening)
- /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
- Image paste no longer inserts a trailing space
- Pasting !command into an empty prompt now enters bash mode, matching typed ! behavior
- /buddy is here for April 1st — hatch a small creature that watches you code
