Claude Code v2.1.133

  • MCP session-expiry errors are now recognized when a 404 response includes "mcp_session_terminated", allowing Claude Code to mark the server as needing auth instead of treating it as a generic failure. Evidence: MCP error classifier (search for "mcp_session_terminated").
  • Compact-cache fallback now preserves abort behavior instead of continuing through fallback paths after cancellation. Evidence: abort checks added around compact cache sharing (search for "Compact cache sharing: no text in response, falling back").
  • Windows command/path handling gained additional normalization and quoting safeguards for daemon spawning, including rejection of unsupported Unicode single-quote variants in generated PowerShell command lines. Evidence: PowerShell quoting guard (search for "unsupported Unicode single-quote in command line").
