OIS, the input library that Odyssey depends on, has released an initial release candidate for version 1.0. This was one of the major things I was waiting for before releasing an SDK version of Odyssey 1.0.
Just so everyone knows, up-to-date versions of Odyssey, including planned 1.0 features, are available from the SVN repo. There aren't too many more things I have left to do before a full SDK release of Odyssey is ready. If you can't wait, grab the latest from SVN and start cracking! I've been using it for some time now and I can promise it is very stable and feature rich.
Don't forget to grab the manual from the (very minimal) project website. It has a lot of good information. It will be updated after 1.0 is released.
