I didn't manage to use the Gettext Commons for the internationalization, but there are some other changes. The changelog:
Version 2.6 (Fre Mai 18 19:40:57 CEST 2007)
New:
* The menu can contain sub-menus; you can insert them with one or two * at the beginning of the line with the target link (Feature Request #1717610)
* List entries (*, #, :, ;) may have arguments (Feature Request #1718195)
Example: * style="color: #f00;" | red text
Notes:
* Designs updated
* Lists are better looking (indent with spaces) (Feature Request #1651883)
* gif images in the style directory are copied too
* The first {{Language:...}} or {{Lang:...}} is taken, thus further ones don't have to be masqueraded with { (causes a { in HTML). The same for all {{something:text}} tags except AddKeywords and Meta.
Have fun!
