Claude Code v2.1.89

Descripción Detallada

What's changed - 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 `CLAUDECODENOFLICKER=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 `MCPCONNECTION_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)
