The build 291.2 is available in the Product Owners Lounge forum.
This is a beta version, please be careful and make backup copies of your MFA files before loading them with this version. Especially because of a change to reduce the memory used by the editor for big apps (even if this was tested internally during a couple of days, you never know).
In case of problem you can reinstall any other version (no need to uninstall first, just reinstall the patch of the build you want to reinstall).
If any problem with this version, please post it in the bug box, don't post it in this forum otherwise the developers won't see it, thanks!
PS: the CF 2.5 patch updates all the installed exporters, you do not need to reinstall them.
