Comment 10 for bug 122316

Version 3.0 will indeed be under GPL 3.0. It is currently Alpha 1 and a few people on the forum having issues compiling it on 9.10. Haven't tried myself yet, but I will!

SVN repo is here: http://code.google.com/p/rawtherapee/

Sounds like the developer is looking to delegate quite a bit, so he should be open to a conversation about packaging it for Debian / Ubuntu...
