we're going to make huge changes soonish to the dev branch... more like we move on to use composer for the plugins, which allows us to use other libraries easily

if you are now at dev, make backup of the current running eXpansion, so you can revert easily if you update mistakenly.
DEV BRANCH auto update will break within next week or two
if you have now running dev continue running it without updating.
Thanks,
Reaby
