Version 0.996 is here. The main new feature is Custom Gibs support. I haven't done the docs for it yet... so use at your own risk of frustration (there is no error checking... and some settings are required for various other settings to work). See the Valve Developer Community for more info on what the settings might do. I'll hopefully have docs in a week.
I've also updated the Compile Errors page to explain some more problems you can run into.
