+# Usage: make-release-desc.sh <version>
+#   <version>: current release version (v<maj>.<min>.<pat>, the leading v is optional)
+#
+# The previous version is the highest plain semver tag (v<maj>.<min>.<pat>)
+# strictly below <version>. The change log lists all commits between the
+# previous version tag and the release commit, one line per commit.
+#
+# The release commit is the commit <version> points at when the tag exists,
+# HEAD otherwise. The nightly release is the b* tag pointing at that commit
+# (release.yml tags the same commit); the link is only generated when that
+# tag exists.

+#   GITHUB_OUTPUT: previous_tag, changelog_title, changelog, nightly and nightly_tag
