### Report an Issue

This part is critical: Please report any issues [at GitHub](https://github.com/emberjs/ember.js/issues), especially regressions from 1.8 or 1.9-beta. If your business has certain browser requirements (IE8 for example) testing on those edge-case platforms today will help us resolve issues in time for 1.10.
