More about this release on Blendernation.
I’ve been using/switching to the Blender 2.5x beta releases since around late last summer (my first test project “space visual – early period” done in 2.5 from last October) and found it more than usable while still being labeled “beta” for a coupe of months already…
Now that the transition from the classic Blender 2.49 with the old loved/feared interface is mostly done (I first feared it, then loved it) expect a quite significant addition of features to Blender for the next couple of releases.
Open-source animation and platform independent video post production have just been upgraded and there is so much more to come now…!
