On December 12, 2018, Microsoft released SQL Server 2014 Service Pack 3 CU1, which is Build 12.0.6205.1. There are 13 hotfixes in the public fix list. If you are running SQL Server 2014, you should be planning on getting on the SP3 branch as soon as possible (if you haven’t done it already). Keep in mind that SQL Server 2014 will fall out of Mainstream Support on July 9, 2019, which means there will be no more Service Packs or Cumulative Updates after that.
Microsoft also released SQL Server 2014 Service Pack 2 CU15 on the same day. It is Build 12.0.5605.1, and it has 7 hotfixes in the public fix list. If you are on the SP2 or an even earlier branch, you should be thinking about getting on SP3 as soon as you can.
