Where is Data Transfer Modifier on Blender 2.73a for Linux? I've noticed that the Data Transfer modifier, as documented on Blender's modifier list in the docs, is not available on Blender 2.73a (at least).  It's just not there.  I can't speak to Blender for other OSes, but for Linux, this is the case.

Can anyone tell me what's going on and what I need to do to enable it?  Is it deprecated now?
The data transfer modifier is new in 2.74, you can download RC1 here: http://download.blender.org/release/Blender2.74/
