Protege 3.1 Beta

There's a new beta build available on our Web site:

http://protege.stanford.edu/download/prerelease/full/
http://protege.stanford.edu/download/prerelease/basic/

Although little has changed visibly in this build, we've made quite a few 
major internal modifications. As a result, this build may not be quite as 
stable as typical Protege beta builds. If stability is a concern for you, 
please wait a while before upgrading. In any case, you should always backup 
your work before upgrading...

Changes
-------------
1. The 2.0 beta version of the OWL Plugin is now included.

2. Protege now directly supports PostgreSQL as a database for use with the 
database back-end. No parameter definitions or other hacks are required to 
make the system work. Thanks go to Andrew Hastie for providing both the 
code and the prodding necessary to finally make this happen. Current 
PostgreSQL users may wish to regenerate their database projects.

3. Made URLWidget loading asynchronous.

4. The "add superclass" control on the Classes tab now respects the 
"allowed parents" facet on the "direct-superclasses" slot. Thanks go to 
Marc Dzaebel for contributing this fix.

5. There is now a mechanism to flush the multiuser server file-base 
projects to disk and shutdown the server. This mechanism is documented on 
our Wiki:
http://protege.cim3.net/cgi-bin/wiki.pl?ShuttingDownTheServer.

6. Reworked the "Include Projects" menu items and their implementations.

7. Fixed a bug occurring in slots which had both inverses and template values.

8. Fixed a bug that caused the final change in a text component to 
sometimes get lost before a save.

9. Removed a very old (Protege 1.X) version of the database back-end from 
the distribution.

10. Incorporated the OWL Plugin toolbar icons into the core toolbar.

11. Added some code to try to ensure that the Help menu remains the last 
menu on the menu bar.

12. Fixed a crashing bug in the UMLS Tab.
