 --------
+* mgr-pg_autoscaler: Autoscaler will now start out by scaling each
+  pool to have a full complements of pgs from the start and will only
+  decrease it when other pools need more pgs due to increased usage.
+  This improves out of the box performance of Ceph by allowing more PGs 
+  to be created for a given pool.
+
 * New bluestore_rocksdb_options_annex config parameter. Complements
   bluestore_rocksdb_options and allows setting rocksdb options without repeating
   the existing defaults.
