Maya 2012 .dae export or Maya 2011, 2010

No big deal, I don't even know what's the difference between them.

Only difference I noticed so far, is that Autodesk managed to break the character sets in Maya 2012. They worked perfectly fine in 2011, but in 2012 it's impossible to animate a rig that's using them with the Graph Editor.
They never fixed it either - I don't know if they work again in 2013. Probably not, because Autodesk is apparently ruled by a pack of chimpanzees!
