2.69 hasn’t officially been released, but there is now a test build, which is practically the same thing (no new features will be added, only bug fixes)
Now before you run away shouting “It’s not the same!” remember that test builds are extremely important. They’re there for you to start using and report any bugs so that the official 2.69 release is mostly bug free. Otherwise we need to do an ‘a’ release. Last time, we nearly had to do a ‘b’ release too because even more bugs were found.
So do everyone a favour and just try it out. Render some old scenes, model something, or check your rigs still work.
