Updates for SharePoint 2013 (April 2018 CU)

A new cumulative update has been released for SharePoint 2013 (April 2018 CU)
This CU fixes all SharePoint 2013 products.

SP Build: ​15.0.5023.1000

This CU is a full update (Uber package), requiring no earlier updates apart from SP1.

The CU includes all SharePoint 2013 security fixes released since SP1. It does not include SP1, which is required to install this CU.

Because of its size, the CU is split into separate CAB files and one executable. Download all these files into the same installation folder before starting the update.

Important

Before installing the CU, ensure SP1 is already installed.

Installation may take up to five hours, so I recommend reading: Speeding up CU and SP installation on SharePoint 2013.

If your farm's patch level is earlier than July 2015 CU, run PSCONFIG immediately after installing the CU to update the schema of certain search databases. More at:
