If you are using SharePoint 2013, you should be aware that mainstream support for SharePoint 2013 SP1 will end on April 10th 2018. After this date only security fixes will be provided for SharePoint 2013. Regular hotfixes can no longer be requested.

It’s time to plan to Migrate to SharePoint 2016 or to SharePoint Online!
