The August 2015 Cumulative Update for SharePoint 2013 contains numerous hotfixes and improvements for SharePoint Foundation 2013 and SharePoint Server 2013. The cumulative update package is multilingual and contains updates for all languages.

Before you start
Since June 2014 the Cumulative Updates for SharePoint products releases on a monthly basis.

This cumulative update includes all patches since the Service Pack 1 release, but not the Service Pack 1 itself. You must install the Service Pack 1 before installing this cumulative update. Read how-to install Service Pack 1.
Because of the file size the cumulative update package has been divided in three parts; ubersrv.exe, and You have to put them all in the same folder.
The July CU changes the database schema for the Search analytics reporting database to support URLs up to 4000 characters. The Search crawler expects an updated database schema and is going to fail if the SharePoint Configuration Wizard (psconfig) hasn’t been run right after the installation (follow the installation instructions below).
