OmegaWiki has been successfully upgraded to the brand new MediaWiki 1.17.
Most of the changes are internal things (the database structure has changed, and several things had to be rewritten here and there to be compatible with the new version).
As a user, you might notice that everything still works like before :)
You will also experience the new interface (Vector) which is now default, like in the Wikipedias. The old interface (Monobook) can be activated in your preferences.
The upgrade also permitted to get the latest translations for the interface and to upgrade the extensions. Some of them where 1-2 years old.
Feedback on any bugs that you may find are more than welcome.
