I just released 0.7.13.3, which is mainly an update to the mac package on GoogleCode. It now includes the new, experimental Ruby 1.9.1 wrapper, so let me know if you have any problems with that :)

Other than that, I am continuously working on the rdoc. It now includes lots of content from the wiki. Once I figure out how to turn the C++ doxygen output into something usable, both documentation sets should be an all-in-one documentation for their respective language.

I actually re-released the only missing package (Win C++) after realizing that the old version didn't have the new, slightly extended font interface (you can get the name() of the font after creating it, and you can give it other font flags than plain bold).

I dont know if this is of any interest but i just found MacRuby  (unfortunately only mac). I might have been abit slow on this, I dont know how you are implementing 1.9 support in the new version, but this seems like a good way of including 1.9 with any mac app. There is even a handy screen-cast on how to include it in your apps.

I am very interested in MacRuby and getting Gosu to work with it is on the To Do list :) If the LLVM backend leads to Ahead Of Time Compilation, that would solve some very interesting problems.

The downside is it relies on Leopard's garbage collector and Objective C 2.0 in general, and I want to support Tiger for some more time. So I'll probably stick to 1.9.1 for deployment until something better comes along.
