Adobe announced the Adobe AIR and Flash Player Incubator program a few days ago. This is a place where the Adobe team shares features under development or experimental with the community so they can test it and give feedback.
The first Adobe Flash Player build has already landed in the "Incubator" - but please note that this is a preview release so only use it for testing purposes. This release brings Cubic bezier curves (using the cubicCurveTo drawing API, developers can easily create cubic beziers without requiring custom ActionScript code) and new 3D APIs:
Today, Adobe Flash Player 10.1, renders thousands of non z-buffered triangles at approximately 30 Hz. With the new 3D APIs, developers can expect hundreds of thousands of z-buffered triangles to be rendered at HD resolution in full screen at around 60 Hz.
