I've put this together for my own benefit while pulling apart the new enhancements.
If, like me, you prefer to get an overview of things in a presentable format, and something that you can scribble on to help your thinking, then hopefully this will be of benefit.
Alpha enhancements in PDF format
I'll add to this as the new classes become available and as other changes are made. Or if I look back at something which makes perfect sense to me right now, but makes less sense when I go back to in a few days then I'll tweak it. There's a very good chance of a few typos or missing connectors between enhancements, if you see any let me know and I'll correct.
This won't provide every single detail of the enhancements, if you want that, then please refer to EllisDee's detailed list of enhancements.
