PR with old commit that waited for a long time before merging may be listed for wrong release.

For example github_changelog_generator gravitystorm/openstreetmap-carto --no-issues lists adding antarctic icesheet rendering based on preprocessed shapefiles (gravitystorm/openstreetmap-carto#1540) for v2.30 instead of v2.32 - see gravitystorm/openstreetmap-carto@v2.31.0...v2.32.0
