The system detected EasyApache 4 template changes

I received an email today: The system detected that one or more templates were updated as a result of a change in the EasyApache 4 environment. The following ".default" template has changed in a recent update in the EasyApache 4 environment.

• ea4_main.default

We identified corresponding ".local" template for the above mentioned ".default" template on your system. Update them as soon as possible to avoid problems. The system generated this notice on 2018-03-07 at 00:48:06 UTC. I did some research on the forums but could not find anything 'directly' related to the ea4_main.default template. Is this something I should be concerned about or need to do something?
