About Release Management for TFS Update 2
If you plan on upgrading your Release Management installation from update 1 to update 2, here is a bit of advice: Do not. I tried in our internal installation, and everything broke down. The worst part was the TFS integration. It was no longer possible to link a TFS build definition to a release template, rendering them completely useless. And since RM for TFS is all about release template, the whole release infrastructure was absolutely blocked. I will wait for the next update and hope Microsoft will fix these issues. As a side note, deploying a brand new Update 2 installation did not fix the TFS issues, so apparently it is not related to the upgrade process. EDIT (2014-08-22): I have upgraded to Update 3 without problem. It was probably a bug corrected in the last version.
