As you might have heard we've been working on Wikidata
(http://meta.wikimedia.org/wiki/Wikidata) for a few months now. The
first phase of Wikidata is about centralizing language links in
Wikidata. We are getting close to a first deployment of this on the
Hungarian Wikipedia and then probably the Hebrew or Italian Wikipedia.
I wanted to give you a heads-up about this.
A few people have already started working on bots to migrate language
links to Wikidata where desired. (The current system will continue to
work.) This includes the PyWikidata library. You can find the current
state here: http://meta.wikimedia.org/wiki/Wikidata/Bots.
I also wanted to let you know that we'll unfortunately have to break
the API after deployment. I'll keep you updated on this. It might be
wise to wait for that to happen before transitioning existing bots.
