My client shows SQL Server Version 13.0.5101.9 which should have put it in late 2018 but the description and KB numbers and the date of release is July 9 2019 and another build also on July 9 2019 puts the build number, 13.0.5366.0 which is consistent with the date.
The first July 9 2019 with the earlier build number is KB4505220, the second that puts the build number at 13.0.5366.0 is KB4505222.
One is for CR7 and one is not but if you are on 5101.9 how do you get to a more current build number?
