Update Rollup 5v2 is released, v1 was pulled hours after release because of a DAG issue, this is fixed now.
Todays rollups also include security fixes for Microsoft Security Bulletin MS12-080. The Exchange team have the strange practice of using the rollups as the only vehicle for Exchange security fixes. This forces customers to deploy a complete rollup to be compliant. This year Exchange rollups were pulled 3 times because of quality issues, so in my opinion security fixes should also be made available as separate installers.
