Is anyone else running SL1 v12.1.2?

We were supposed to be upgraded to v12.2 but problems with Aurora (the AWS database offering) we have ben placed onto v12.1.2.
We were handed the system on September the 9th, and the release notes are dated the 10th. 
It has zero backward compatibility with collectors (all must be on 12.1.2) and we've been plagued with critical system alerts before we even attached a collector. 

I kind of get the feeling that we're alpha testing this release.... ☹️

Can anyone else, give me some comfort and confirm that we are not the Guinea Pigs for this release?
