EDIT 17.11: the build 283.3 has been updated to address a problem with collision detection in 64-bit iOS apps.
The build 283.3 (pre-release) is available in the Support Forums / Product Owner's Lounge / Fusion 2.5 forum.
The CF 2.5 patch updates all the installed exporters, no need to reinstall them.
If you use the iOS exporter, please do a Project / Clean in Xcode before rebuilding your iOS app, as usual with each new build or when you update Xcode.
This build will be the next official build, unless unexpected issue.
Make backup copies of your MFA files before loading them in this version anyway, just in case...
Let us know if any new problem, thanks!
