Poem

🐰 A rabbit hops through version lands,
Where changelogs update with careful hands,
Five-point-oh rises, bright and new,
PayButton dances—5.2.0 too! 🎉

6-6: Version metadata updates look correct (aside from Stable tag issue).

The updated metadata is consistent:

• WordPress compatibility bumped to 6.9
• PayButton Client dependency updated to 5.2.0 (matching the changelog entry at line 87)
• Comprehensive 5.0.0 changelog entry with clear feature descriptions

Once you fix the Stable tag, all version metadata will align properly.
