Basically, all Toy varaibles, functions, etc. are prepended with "Toy_", and macros are prepended with "TOY_". This is to reduce namespace pollution, which was an issue pointed out to be - blame @GyroVorbis. I've also bumped the minor version number - theoretically I should bump the major number, but I'm not quite ready for 1.0 yet.
