Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.64

  • Fixed stale lock file handling: lock files can now be force-removed when they become stale, with logging of the cleanup (search for "Force-removed lock file at")
  • LSP diagnostics state is now properly reset when clearing state, preventing stale diagnostic data from persisting (search for "LSP Diagnostics: Resetting all state")
  • MCP config validation now produces clearer error messages: "--mcp-config validation failed" and "MCP config is not valid JSON" replace generic parse errors (search for "--mcp-config validation failed")
  • Symlink-aware path resolution added for filesystem operations, properly following symlinks through intermediate path components (search for "isSymbolicLink" in function Oiq)
