This is the fourth bugfix release of Luminous v12.2.x long term stable
release series. This was primarily intended to fix a few build,
ceph-volume/ceph-disk issues from 12.2.3 and a few RGW issues. We
recommend all the users of 12.2.x series to update. A full changelog is
also published at the official release blog at

We're happy to announce the third bugfix release of Luminous v12.2.x
long term stable release series. It contains a range of bug fixes and
stability improvements across Bluestore, CephFS, RBD & RGW. We recommend all the
users of 12.2.x series update.
Notable Changes
---------------
*CephFS*:
* The CephFS client now checks for older kernels' inability to reliably clear
dentries from the kernel dentry cache. The new option
client_die_on_failed_dentry_invalidate (default: true) may be turned off to
allow the client to proceed (dangerous!).
For the full changelog with links, please refer to the release blog at
http://ceph.com/releases/v12-2-3-luminous-released/. We thank everyone
for contributing PRs, reporting bugs and helping make luminous
luminescent. Many thanks to Yuri for keeping the QE runs across the
components green.
