I just updated to the June 2019 CU (build no 15.0.5145.1000) onto our SharePoint 2013 test environment.
All went well and the upgrade completed successfully without any issues.
But when checking 'Servers in the Farm' from Central Admin the Configuration database version is shown as 15.0.15131.100
rather than 15.0.5145.1000
.
Is anything wrong?
