Important Update - 21st October 2015: There have been a few reports about a bug in this latest management pack - which seems to have also been present in the previous MP release - where the SQL database logs on your DW server can fill up in certain scenarios. For this reason, it's a good idea to hold off deploying these MP's into production until Microsoft release a fix for this (as far as I know, Microsoft are aware of the issue and are working on a solution).
The previous release (version 22.214.171.124) brought a new dashboard template and visualizations....
Thankfully, Microsoft have identified this as an issue and have listed this as a fix in the latest 126.96.36.199 release of the MP:
I've deployed this updated MP into my lab and so far, it seems to have fixed the issue for me - although it took a few days to manifest itself in the last MP so let's see how this one goes!
There's also a few new visualization options that you can choose from as you can see from Microsoft's post on the new MP's here.
You can download the new SQL management packs using the SCOM MP Wiki or directly from here (SQL 2012) and here (SQL 2014).
Note: As of the time of writing this post, these updated MP's are not available through the built-in catalog option in SCOM but I'd expect them to light up there in the coming days too.
