- Component system: abstract display management, rendering, audio playback and other external libraries in a generic way
- Shader support (still needs a lot of work though)
- Pyrex -> ctypes switch
In case someone didn't realize already, Spineless is undergoing a massive rewrite, including shader-only rendering, easier extensibility, no compiling required (thanks to ctypes) and lots and lots of cleanup all over. There's still a huge amount of work left, but at least the work is proceeding much faster now.
Did I mention I love ctypes?
