How do I install a theme on MyBB 1.2.13?

I guess the same way you'd do it on any other version. ACP > Themes > Import!

BTW when did we come out with a 1.2.13? I thought 1.2.12 was it untill 1.4?

And what has changed since will all my themes still work? Or do I have to download 1.2.13 and start designing for 1.2.13 now?

I don't think so.. The announcement says just replace the files, the upgrader isn't even needed. So I guess no template changes.

1.2.13 was just a security update, so it shouldn't have anything to do with themes.
