v12.2.10 Luminous
=================
This is the tenth bug fix release of the Luminous v12.2.x long term stable
release series. The previous release, v12.2.9, introduced the PG hard-limit
patches which were found to cause an issue in certain upgrade scenarios, and
this release was expedited to revert those patches. If you already successfully
upgraded to v12.2.9, you should **not** upgrade to v12.2.10, but rather **wait**
for a release in which http://tracker.ceph.com/issues/36686 is addressed. All
other users are encouraged to upgrade to this release.
