# Upgrades - Appendix v2.0

Important
v2.0 of Maian Affiliate sees the removal of the Savant3 template engine (now officially abandoned) in favour of the Latte template engine. ALL previous themes will NOT be compatible with this new template engine and all themes will need to be rebuilt for the new Latte variables.
We apologise for this inconvenience, but this is an impportant security step going forward as Latte is a faster, more modern and secure template engine.
