Just to let you know, "Final Minetest" is just a dumbass fork run by a hostile third party, and wasn't really the result of the version number change and its associated breakage (which actually is fairly minimal, all of my mods still run just fine, only a couple needed minor changes).

That third party has been engaging in attacks against Minetest (and other unrelated parties) for a few years now, after getting all butthurt over the temporary loss of a popular feature that was actually the result of an engine bug (I.e. the bug was fixed, then the feature was added back as a config option).

I highly recommend you avoid any and all contact with that project and anyone who support it or its ... maintainer.

The real Minetest is and always will be at minetest.net (as far as I know :P )
