update-changelog

Update the repository changelog with changes between the last release and the current version (main) that are not yet incorporated. If CHANGELOG.md does not exist, use CHANGELOG instead.

Determine baseline version If no baseline version is provided, use the most recent git tag. You can find it with git describe --tags --abbrev=0.

Update the changelog Read the existing changelog file (CHANGELOG.md, or CHANGELOG if missing) and check if there are changes not yet incorporated, then add them. Always add them to the "Unreleased" section only. If there is none yet, add it at the top in the same style as the existing changelog (for example, ## Unreleased vs ## [Unreleased]).
