Microsoft has released a cumulative update for SQL Server 2008 R2 SP2, which was only released last week.
My recommendation: if you have already installed Service Pack 2, or were waiting on the first cumulative update before doing so, this may be what you've been waiting for. According to the SQL Release Services Blog, SP2 CU#1 includes all of the fixes from SP1 CU#6 and CU#7 (which were not included in SP2 RTM).
My usual disclaimer: these updates are NOT for SQL Server 2008. Only apply to systems where @@VERSION returns 10.50.xxxx, where xxxx is >= 4000.
