Couple of XIBO questions

Hello,
I have two questions; we have external MySQL DB:

  1. Looking at this page: GitHub - xibosignage/xibo-cms at master

image

For production environment, is “master” recommended or “release20” (not sure if they are different)?

  1. For “release20”, which looks like 2.0.3, is MySQL 5.7 supported now?

Thank you!
