VMware released the extended service branch last year. For those of you not familiar with it, I’ve published a previous article on it so please check it out.

I’ve found it pretty difficult to get information until now on when the first service pack had been released. Luckily, VMware have now produced a kb which contains the information:

As you can see the versions that equate to SP1 are:
Horizon 7.5.2
App Volumes 2.14.3
UEM 9.4.1
UAG 3.3.1
So if you’re on the ESB release track, these are the versions you should upgrade to if you want to remain compliant.
