How 'beta' is v2.0 for OpenGL?

Hi all,

I have an existing project that I want to resurrect. I currently have it working in 1.5.1, but I need to do some significant additional development.

I'm tempted to move to v2.0 given the new OpenGL features and the fact that this will be the only way forward in the future.

So, how risky would an immediate move to 2.0 be? The project makes extensive use of OpenGL rendering for playing movie files and better rendering of fonts etc.

Any comments gratefully received.
Cheers,

Chris
