Today the SQL Server Release Services Team has pushed out new cumulative updates for SQL Server 2008 R2:

Cumulative Update #14 for SQL Server 2008 R2 RTM

 – KB article http://support.microsoft.com/kb/2703280
 – build number 10.50.1817.0
 – 7 fixes
 – relevant for builds between 10.50.1600 and 10.50.1816 

Cumulative Update #7 for SQL Server 2008 R2 Service Pack 1

 – KB article http://support.microsoft.com/kb/2703282
 – build number 10.50.2817.0
 – 24 fixes
 – relevant for builds between 10.50.2500 and 10.50.2816

As usual, I'll post my standard disclaimer here: these updates are NOT for SQL Server 2008 (where @@VERSION will report 10.00.xxxx).

And an additional disclaimer: do not install either of these updates if you have installed SQL Server 2008 R2 SP2 CTP.

And one more: this is highly likely to be the last CU you'll see on the RTM branch.
