In case you had nothing else to do this week.
As you know, each CU is truly cumulative in that it is a large hotfix that pulls together all previously released hotfixes into a single distribution. When customers need to apply the latest fixes, they only need the very latest CU.
SQL Server 2014 CU4 has released, and it contains over 50 hotfixes. Installing CU4 will take SQL Server 2014 to the latest build: 12.0.2427.0.
