Claude Code v2.1.63

  • Fixed race condition where concurrent config writes could wipe authentication data from ~/.claude.json (search for "See GH #3117")
  • Improved OAuth callback handling with better error message when the redirect URL is missing the authorization code (search for "Invalid callback URL: missing authorization code")
  • Fixed "Prompt cancelled by user" error propagation when prompts are cancelled during hook flows (search for "Prompt cancelled by user")
  • Improved orphaned version cleanup with better error handling for stat failures (search for "Failed to stat orphaned marker")
  • MCP server .mcp.json writes now use atomic datasync + rename pattern with proper file permission preservation, replacing the previous simpler write approach
