Does anyone know how to do these things in 2.40? I’ve been using 2.37 and these features went away. 
Alt-B doesn’t do edge loop selecting anymore. What it does is cool, but I kind of need edge loop selecting!
In proportional modifying, the +/- keys no longer change the radius of effect. I can’t find any two keys that change the size of that circle anymore.
In Bone Pose Mode, Alt-G and Alt-R will clear the bone’s grab/rotation, but Alt-S doesn’t clear its scale – instead it affects the bone’s envelope. How, without using the mouse, do I clear a bone’s scale? (Usually you do this when you’re returning the skeleton to the unposed position).
If I want to parent some object, say a hat, to a single bone in the skeleton, how do I do that? I used to have in the Ctrl-P menu a “parent to bone” but now I can only choose “object” or “vertex groups from closest bones.” No way to set parent of a single bone in the armature.
If I load up an old file where an object was child of a bone, it works, but there doesn’t seem to be a way to do it with a new file.
Thanks, everyone!
By the way, I suspect these are only problems in the Linux version of Blender, since I don’t think these bugs would have made it into 2.40 if they were bugs in the Windows version.
