Release Notes
===============
+v12.2.1 Luminous
+================
+
+This is the first bugfix release of Luminous v12.2.x long term stable
+release series. It contains a range of bug fixes and a few features
+across CephFS, RBD & RGW. We recommend all the users of 12.2.x series
+update.
+
+For more detailed information, see :download:`the complete changelog <changelog/v12.2.1.txt>`.
+
+
+Notable Changes
+---------------
+
+* Dynamic resharding is now enabled by default for RGW, RGW will now
+ automatically reshard there bucket index once the index grows beyond
+ `rgw_max_objs_per_shard`
+
+* Limiting MDS cache via a memory limit is now supported using the new
+ mds_cache_memory_limit config option (1GB by default). A cache reservation
+ can also be specified using mds_cache_reservation as a percentage of the
+ limit (5% by default). Limits by inode count are still supported using
+ mds_cache_size. Setting mds_cache_size to 0 (the default) disables the
+ inode limit.
+
+* The maximum number of PGs per OSD before the monitor issues a
+ warning has been reduced from 300 to 200 PGs. 200 is still twice
+ the generally recommended target of 100 PGs per OSD. This limit can
+ be adjusted via the ``mon_max_pg_per_osd`` option on the
+ monitors. The older ``mon_pg_warn_max_per_osd`` option has been removed.
+
+* Creating pools or adjusting pg_num will now fail if the change would
+ make the number of PGs per OSD exceed the configured
+ ``mon_max_pg_per_osd`` limit. The option can be adjusted if it
+ is really necessary to create a pool with more PGs.
+
+* There was a bug in the PG mapping behavior of the new *upmap*
+ feature. If you made use of this feature (e.g., via the `ceph osd
+ pg-upmap-items` command), we recommend that all mappings be removed (via
+ the `ceph osd rm-pg-upmap-items` command) before upgrading to this
+ point release.
+
+* A stall in BlueStore IO submission that was affecting many users has
+ been resolved.
