SQL Server 2017 CU1 is Available

On October 24, 2017, Microsoft released SQL Server 2017 Cumulative Update 1, which is Build 14.0.3006.16. This CU has 68 hot fixes by my count, which is a fairly high count. This shows that Microsoft has been busy fixing issues that have shown up since the RTM build. I think this is a good thing.

Keep in mind that Microsoft has revised their servicing model for SQL Server 2017, with what they are calling the Modern Servicing Model for SQL Server, as I discussed here.

The gist of this new servicing model is that there will be no Service Packs for SQL Server 2017. Cumulative Updates will be released every month for the first year after GA, on the 3rd Tuesday of each month. After that, they will be released every three months, for the next four years, until SQL Server 2017 falls out of Mainstream support on October 11, 2022.

This means that hot fixes will be available more quickly during the first year, when most of the issues are discovered and corrected. You don’t have to install every single CU when it is released, but you should make a habit of looking at the fix list for each CU, to see if anything that might be affecting you is included. Once you do install the latest CU (which Microsoft recommends you do proactively), you will have all of the hotfixes since RTM, since they are actually cumulative in nature, as the name suggests.
