Note: Any CU's published later than June 2013 are Post SP2 updates! So SP2 is recommended to have before installing the CU. See also here for more information:http://blogs.technet.com/b/steve_chen/archive/2013/07/24/3586568.aspx The June 2013 CU for SharePoint and Foundation is considered as a "Post-SP2 CU" and is NOT INCLUDED into the SP2!

Starting with the July 2014 CU, the release cycle is now every month rather than the Bi-monthly cycle.
(The number sometimes can be slightly different then shown in your central admin page after install, see also here for more!)

Further instructions and information: After installing the packages, you may be prompted for a reboot of your Server! Please don't forget to run the PSConfig Wizard anyway, even after reboot just to ensure that all updates has been applied completely and successful! As usual, you can use the command line on each server in Farm: psconfig cmd upgrade inplace b2b -wait
