/release-notes stops at v2.1.39, missing newer versions

What's Wrong?

The /release-notes command only displays versions up to v2.1.39. Newer versions (2.1.41 through 2.1.56) are not shown, even though GitHub releases exist for them.

What Should Happen?

/release-notes should display all available release notes up to the currently installed version.

Steps to Reproduce

1. Update to latest Claude Code (2.1.56)
2. Run /release-notes
3. Observe that the output stops at v2.1.39

Is this a regression?

Yes, /release-notes previously showed all versions.

Claude Code Version

Platform

Claude Code CLI (native installer, bun-based)

Operating System

Additional Information

The GitHub releases themselves exist (confirmed via gh release list). The issue appears to be in how /release-notes fetches or displays them, not missing releases on the GitHub side.
