The Exchange team rereleased the following Rollups:

• Exchange 2007 SP3 RU8 v2
• Exchange 2010 SP1 RU7 v2
• Exchange 2010 SP2 RU4 v2, including fix for KB2756987

These v2 updates solve an issue with a prematurely expiring certificate used to sign the update (see KB2749655), i.e. no code changes (apart from KB2756987).

The Exchange Versions, builds & dates page has been updated accordingly, including updated product version numbers.
