SQL Server 2016 SP2 CU2, SP1 CU10

Fixes and improvements:
• DAG improvement – automatically seed replicas – when you add a database to an existing AG, SQL Server can automatically seed it across the secondary replicas. .
• AGs – configurable session_timeouts
• AGs – slow transactions with 1 sync and 1 async secondary
• AGs – on cross-data-center AG failover, you get a non-yielding scheduler and a crash
• AGs – queries on secondary take twice as long
• AGs – VSS backups fail on secondary replicas in a Basic Availability Group (which technically you’re not supposed to do, but you can still back up the entire secondary VM, and that’s where the problem looks like it’s coming in)
• AGs – fixing error 19432 for duplicate log blocks
• Log shipping – add support for Transparent Data Encryption by configuring MAXTRANSFERSIZE.
• Dynamic data masking doesn’t
• SSAS crashes when Process Full follows Process Clear –“you will notice that the SSAS may crash.” .
• Memory dump when you merge partitioned temporal tables .
• Stats updates can get a “corrupted index” message and a disconnect
• Assertion error when you add a database
• Slow performance when Query Store is enabled
• Non-yielding schedulers require a reboot – not the most informative KB article ever. “Assume that you have a Microsoft SQL Server 2016 installed.” .
