AwayPhysics support for Away3D 4.1

[kirittanna]

The current version of AwayPhysics doesn't support Away3D 4.1. I see there's a dev branch (probably work in progress?) for the 4.1 release but not sure if its stable. We want to use the new GPU particle system that comes with 4.1 for a demo we're working on but we also need physics for the simulation.

Do you have an estimated release date for 4.1 support?

the dev branch is works fine with Away3D 4.1, just has an issue with ios build.
