GUIlib 1.1.0 is now available:
http://www.devolution.com/~slouken/SDL/projects/GUIlib/index.html
The main reason for this release is the passing of the torch to Rainer
Loritz, who will be maintaining the GUIlib library. He has added more
font support, menus, and enhanced the button widgets. Rainer can be
reached at rloritz at gwdg.de.
I also ported this to MacOS.
Enjoy!
