Change Details

Modified: Scripts/get-repo-changelog.sh:19

• Removed: | head -20 pipe limiting changelog to 20 entries
• Impact: SDK update PRs (via .github/workflows/sdlc-sdk-update.yml:213) will now include complete changelog between versions

Considerations validated:

• No performance concerns (GitHub API handles commit lists efficiently)

• Script maintains proper error handling for empty changelogs
• No tests exist for this script (verified via glob/grep searches)
