[O] 8.3 git head new math $ behavior

[Ken Mankoff]

I've started running the git head version of Org mode, since 8.3 
has some features I'm interested in that were not in the version I 
was previously using (the latest on elpa).

Is this list an appropriate place to as questions or mention bugs 
I find in 8.3, or is there a better place for that?

I write because in the new version $x$ exports to latex as before, 
but ($x$) does not. It exports as seen, including the dollar sign. 
($$x$$) does export as math.

Is this an intentional changed behavior? Or some regex exporter 
bug that I've come across?

 -k.
