This one wasn't announced but it's been in the repository for a while now. Vector built mozilla-firefox 3.0.3 for VL 6.0. There are no language packs built yet.
It does have at least one problem: installing into VL-Light 6.0 alpha 0.11 it fails for a dependency (gconf 2.19). Installing with the --no-dep option works just fine. It looks like the slack-required file needs to be changed to remove the unnecessary dependency.
