I've updated the english master entities for all core and some optional modules on translate.silverstripe.com. This unfortunately didn't happen for a while (sorry guys!), so there's a flurry of new stuff to translate!
The blog module has been added on translate.silverstripe.com, and currently has one lonely german translation - hopefully more translation will follow soon :)
In further news: We're now tracking progress of translations for core and optional modules separately, to more accurately show if a translation is already useable for the core features.
