Quick status update: not much happened due to a variety of reasons, but there is still some progress to report.
The most important piece of news is that the Mediawiki plugin should
be on its way to Debian sid by the time you read this, as the new
gforge-plugin-mediawiki binary package (it'll have to go through
NEW, but that seems to be rather fast these days). Testing and
reporting and bugfixing are most welcome, of course.
I also went through a round of cleanups in the packaging. No more Lintian overrides, far fewer Lintian errors and warnings, and some fixes for PostgreSQL 8.3 compatibility.
