Microsoft has released SQL Server 2014 RTM Cumulative Update 2, which is Build 12.0.2370.0. It has 48 hotfixes in the public fix list.
This is one of the more interesting fixes:
FIX: Intense query compilation workload does not scale with growing number of cores on NUMA hardware and results in CPU saturation in SQL Server
As usual, I recommend that you install this CU if you are using SQL Server 2014, because of the relatively high number of significant fixes in this build.
