Unfortunately we were not accepted for Google Summer of Code 2015.
We had 3 successful years of participation, with a 100% completion rate and we are very thankful for that.
Ogre3D was neither accepted this year nor last year. Mozilla also apparently didn't make it. It seems that a lot less organisations were accepted this year (2015) compared to 2014.
The accepted organisations can be seen here: http://www.google-melange.com/gsoc/org/list/public/google/gsoc2015
