• Use Goreleaser's new ability to generate release notes with AI https://goreleaser.com/customization/changelog/#enhance-with-ai I commented this out for now as we had to revert back to an older version of GoReleaser Pro because of Environment overrides seem to be ignored since 2.6.0 goreleaser/goreleaser#5491 which is fixed in GoReleaser but not released yet
