[WWdevel] impending 2.2.1 release

[Sam H. <sh...@ma...>]

Hello WeBWorK Team,

I'm preparing to release WeBWorK and PG 2.2.1. Here are the changes  
that have gone in so far:

http://devel.webwork.rochester.edu/twiki/bin/view/Webwork/ 
WeBWorKRelease2pt2pt1
http://devel.webwork.rochester.edu/twiki/bin/view/Webwork/ 
PGLanguageRelease2pt2pt1

As usual, please let me know if you have any "pet bugs" you'd like  
fixed before this release. I'm planning to do the release tomorrow  
night unless you tell me about bugs.

Thanks.
