Claude Code 2.1.226 and 2.1.225 landed close together, but they should not be treated as equivalent upgrade events.

The 2.1.226 release note is intentionally terse: it describes bug fixes and reliability improvements without listing a new workflow or user-facing capability. The concrete upgrade checks are concentrated in 2.1.225.
