According to our fancy status page only a small number of translations is available for Drupal 4.6. I've been asked by Dries to urge translators to branch translation projects for 4.6. The translations might not fit in all cases but having a small set of translated strings is better than no translated strings. The more common strings also do not change that often between versions. If there are any problems, add comments to this post and I'll see what I can do.

Cheers,
