I think we should update the credits by adding our names and updating the date (currently: 2011. Should be: 2011-2013). But I think, it is difficult to distinguish between active and inactive/old team, especially concerning version 0.6, since the old team had worked on this release, too (long time ago).
It would be nice to have names added before beta2 already. Some documentation refers to "new team", so having only old team names there would be confusing. I can add myself, but I don't know which name (whether real or pseudonym) you want to use so you have to add yourself. But I'm not postponing beta2 for this.
