Just was doing some testing and fixing for PermissionAsk. That is used to ask for cam, mic, devicemotion, deviceorientation. We think we have it working great now. In ZIM 018 we are removing the sensors parameter in the Frame and having the needed sensor events added in PermissionAsk, but in 017 we still need to add sensors:true to Frame. If you are using PermissionAsk, you might want to test your apps to make sure they are working fine. Let us know if there is any problem.
We have tested on iOS and Android - but not a chrome book. We have updated the docs with newish examples. Pretty well the same as the old ones but commented more and took out examples that did not use PermissionAsk.
