+If, after applying the rules above, no entry remains, do **not** publish an empty section and do **not** pad it with internal changes. Use this single bullet instead:

+- Maintenance release with no functional changes: version bumped to keep numbering aligned with eXeLearning for consistency across related projects.

+Also tell the user which PRs were discarded and why, so they can confirm the release really has no user-visible content.
