ACF 2018 Beta was recently released. It’s not possible to be completely compatible in such a short time frame, but this is important for many users of ACF and Lucee. So the LAS team has already started chipping away at the list of features and changes Adobe are soon to introduce. Kabang might be more compatible than you realise…

Lucee already supports a lot of features new to ACF 2018:
