Microsoft has released SQL Server 2014 RTM Cumulative Update 5, which is Build 12.0.2456. This cumulative update has 47 fixes in the Public hotfix list.

This handy Microsoft KB article “SQL Server 2014 build versions”, lists all of the cumulative updates that have been released for SQL Server 2014, including this one. If you have not already done so, I strongly recommend that you take a look at this KB article “Recommended updates and configuration options for SQL Server 2012 and SQL Server 2014 used with high-performance workloads”, which is full of very good information about how to configure SQL Server 2012/2014, along with quite a few reasons that you should try to stay current with your SQL Server cumulative updates.
