"""Usage: release_notes.py <version> > RELEASE_NOTES.html
Generates release notes for a Kafka release by generating an HTML doc containing some introductory information about the
release with links to the Kafka docs followed by a list of issues resolved in the release. The script will fail if it finds
any unresolved issues still marked with the target release. You should run this script after either resolving all issues or
moving outstanding issues to a later release.
