Be able to see Discord Canary Changes

Android alpha testers are able to know exactly what changes were made since Jethro always lets us know when he posts a new APK.

It would be amazing if the same thing could happen with Discord Canary. A channel for Canary testers to see exactly what each update is for. This could be a channel where a developer posts what has been changed or a Google Doc that contains Git commit notes.

This will help benefit Discord beta testers by allowing us to know exactly what new features/fixes to play with and try to find bugs in.
