+v1.10.2

+This is a minor bugfix release, addressing some Sync-related issues: purge for

+again, and manually triggered Sync has been fixed on PostgreSQL.
+
+Some UI glitches have been addressed, and a few problems appearing only in
+certain conditions - related to Configuration Baskets, our Self Service REST API
+and the Activity Log.
