We need to quickly release a new build for Steam so a quick beta version with only a few changes is available in the Product Owners' Lounge forum. If no major issue is reported we'll release it as official build.
The main changes are the names of the alterable values/strings/user animations for qualifiers, as well as the unlimited alterable values at runtime (Windows runtime only in this version).
If you have big apps that use qualifiers and/or global objects and that use the "Save/Load App/Frame Position" actions we would appreciate if you could test them with this build, as they might be affected by the changes in case of bug (though the changes are pretty safe I think).
PS: there is no change in the Android/iOS/Html5/SWF exporters compared with the build 282.0. If Fernando or Anders have released (or sent you privately) intermediate beta versions of the Android/SWF/iOS exporters since the build 282.0 was released you'll have to reinstall them after applying the 282.1 patch.
