Improvements and fixes
This update fixes the following issues:
When you run a full synchronization in the User Profile Service Application, user profile synchronization cannot synchronize values for Business Connectivity Services (BCS) custom user profile properties (multivalued).
When you try to synchronize a custom time zone from a Business Data Connectivity (BDC) database to a User Profile Application (UPA) database, you receive the System.InvalidOperationException exception.
When SharePoint Server 2013 consumes search from Microsoft Office 365 (hybrid search with SharePoint Server 2013 and Office 365), private groups are not returned.
During a high query load, search may leak flow handles. When all flow handles are consumed, you receive the "Something went wrong" error instead of the query result.
