Is it necessary to update Edrawings when moving from Solidworks 2017 to 2018?

Updating our installation to 2018.  Sales team used Edrawings to view our drawings. 

I see nothing on the Edrawings download page clarifying if the download is 2018 or 2017.

If a new installation of 2018 Edrawings is indeed required, it would be nice to have a link to send to the sales team that clearly indicates it is the 2018 vers
