Just in time for the holidays...

version 2 of The List:     22 bugs
version 2 with papercuts*: 27 bugs

This list represents some of our most pressing needs. Missing however 
are any maildir bugs which probably should be added RSN if there is to 
be any hope of getting users to adopt maildir in the TB24 era.

The List version 1 was 32 bugs. 12 closed as follows: 9 fixed, 2 WFM, 1 
dup to a fixed bug.

In version 2, 787618 is removed and added to tb-enterprise. four are 
added: 794303, 794303, 815012, 471492.  These were culled from confirmed 
bugs only created since The List version 1 as follows: 
severity=major+critical, regressions with sev=normal.

* Note: it is still the case that not all papercut bugs are labeled as 
such in bugzilla. So "version 2 with papercuts" is incomplete with 
respect to papercuts.  It would be good for someone to take on that task.
