I havent really noticed, and there may be a reason for that, but are there special code names for UbuntuMate or are they just going to share the corresponding Ubuntu names? Just wondering for making wallpapers and stuff.
As an official flavour we follow the Ubuntu codenames.
I can only seem to vaguely remember them, this page has them all:
https://wiki.ubuntu.com/DevelopmentCodeNames
Thats what I thought but wanted to be sure.
