The biggest thing to happen to Aurelia thus far is the release of actual documentation. For months many die-hards (myself included) have been using the limited already provided docs, scouring Github source code and pestering the team on their Gitter chat channel (which I encourage you to join).
The team have created an Aurelia powered documentation application that allows for seamless browsing of the many Aurelia dependencies and their code. It also have various examples and info on how to do things with parts of the framework you probably never knew existed.
The documentation is an ongoing effort by the team and there is plenty more planned. This is only the beginning.
You can check out the documentation here.
