Release 12.11

The GCompris development team is happy to propose you a new version
of GCompris numbered 12.11. This release includes 13 new activities,
probably more than any release of GCompris so far.

GCompris is a popular high quality educational software suite
comprising of numerous activities for children aged 2 to 10.

And when we say multi-activities, we really mean a lot. We now have
136 activities in GCompris!

I would like to give a special thanks to Gnome and Google for their
support in allowing us to have two students working three months
full time on GCompris last summer.

Release 12.05

The release 12.05 is mostly a maintenance release, no new activities
have been included. Many bug fixes and translation updates.
