You’re a data professional and you’re trying to keep up with patching a wide range of SQL Server versions and editions. How do you know what’s in the CU and whether you should apply it or not? My favorite way to read up on CUs is to go to SQLServerUpdates and click around there. It will take you to the latest CU pages as well as give you a way to see previous CUs that are available.
While doing this recently, I discovered this for CU 26 on SQL Server 2017.
These sorts of regressions do slip in, so keep an eye on them before (and after) upgrading. Lee gives us a concreate example of one in a recent CU of SQL Server 2017.
