-### Notes on tagging
-* Tags must be annonated as CMake determines `CEPH_GIT_NICE_VER` by
-calling `git describe --always`.
-* vX.0.0 are special ones in the sense they are pushed manually (unlike v.X.2.n
-which are handled by Jenkins).
-* vX.0.0 should point to a commit before the first one in a kickoff branch.

 - [ ] create branch for new release
+- [ ] create vX.3.0 annotated tag on ``main`` so upgrades from new release to main are not wrongly considered downgrades.
 - [ ] remove ``doc/releases/*.rst``. This should leave behind ``doc/releases/releases.yml`` which is used for doc building purposes. See also commit 33d63c3 ("doc: remove release notes for release branch") for details.
 - [ ] cherry-pick 8cf9ad62949516666ad0f2c0bb7726ef68e4d666 ("doc: add releases links to toc"). There will be trivial conflicts.
 - [ ] add redirect for new major release at `RTD <https://readthedocs.org/dashboard/ceph/redirects/>`_.
