Hi!
Yes, you’ve read it well, mainstream support for SharePoint 2013 will end on April 10th of 2018, after this date only security fixes will be provided for SharePoint 2013. Regular hotfixes in case some bugs have been detected can no longer be requested.

If you haven’t already planned to migrate to SharePoint 2016, this announce should change your mind.
This is not the only thing to consider after this date: starting with April 10th, 2018 the required patch level to request support for SharePoint 2013 will also change.
Currently all patch levels starting with SharePoint 2013 SP1 are supported. Starting with April 10th, 2018 this will change. In order to request support from Microsoft after April 10th, 2018 the SharePoint server farm has be on a patch level of April 2017 CU or later. A year later, after April 10th, 2019, the SharePoint server farm has be on a patch level of April 2018 CU or later.
This change is outlined in the Updated Product Servicing Policy for SharePoint 2013 published on TechNet.
So keep in mind this piece of advice and update or migrate your current farm!! 😉
