Pixel Android gets a rolling release canary channel

To better support you and provide earlier, more consistent access to in-development features, we are announcing a significant evolution in our pre-release program. Moving forward, the Android platform will have aCanary release channel, which will replace the previous developer preview program. This Canary release channel will function alongside the existing beta program.

This change is designed to provide a more streamlined and continuous opportunity for you to try out new platform capabilities and provide feedback throughout the entire year, not just in the early months of a new release cycle.

This new Canary channel is intended for developers, and you can expect a ton of bugs and breaking changes. Updates are basically streamed continuously over the air, but not all changes will make it to a final release of Android (as in, they can be pulled definitively). You can join the new channel with any supported Pixel device, but going back to a beta or final release will require a full wipe.
