Just a heads up, as of v1.4, you should really be on 4.15.2 if you are using 4.15. Epic is starting to require 4.15.x plugins to use 4.15.2 if they have Mac as a target platform due to an XCode issue that requires 4.15.2 to build properly. v1.4 of Able hit a slight road bump due to that new requirement, but it’s been submitted so assuming Mac is building again it should go out hopefully in the next day or so.
Locally, this didn’t require any code changes so if you are on any other platform and using 4.15.0/1 - it should be fine. But, just know I’ve had to update my local environment and so that’s what I’ll be testing on going forward.
