BlackBerry promised that by June the BlackBerry 10.2 SDK Beta would be available. Today is that day with the updates including additions to the BlackBerry 10 Native SDK and both the Android and Adobe AIR run-times.
On the Dev Blog, BlackBerry describes the new 10.2 SDK Beta:
The updates to the run-times have been ones that have had a lot of anticipation. Adobe AIR 3.5 brings with it Stage3D for accelerated OpenGL graphics and the Android run-time upgrade brings it up to Android 4.2 (Jelly Bean) compatibility. As with any beta, this is a work in progress as we work our way towards the gold release of the BlackBerry 10.2 SDK. Known issues will be outlined in the release notes for each run-time.
There are also BlackBerry 10.2 SDK OS updates for BlackBerry 10 Dev Alpha B and C testing devices as well as the BlackBerry 10.2 SDK OS updates available for those who have BlackBerry Z10 and BlackBerry Q10 smartphones. All updates can be performed via the autoloader tool. Again, this is an SDK OS beta that is a trimmed down version of the BlackBerry 10.2 Operating System and is meant to provide a testing environment for you to try out the new SDK and experiment with the added capabilities that have been released. We have also released BlackBerry 10.2 SDK OS updates for the simulator. For this first release, Android 4.2 Jelly Bean testing is not yet supported in the simulator.
