We (Qt upstream) have released Qt 6.8.1 today. As a patch release,
Qt 6.8.1 does not introduce new features but contains more than 550 bug

Release note: https://code.qt.io/cgit/qt/qtreleasenotes.git/about/qt/6.8.1/release-note.md

We (kde@) skipped shipping Qt 6.8.0 due to waiting for a compatible
version of PyQt to be released, but here are the announcements and
release notes from Qt 6.8.0.
