To change what channel you’re on, open “Settings”->“About ChromeOS”->“Additional Details” and click the “Change channel” button. The developer channel gets updated multiple times per week, shipped with whatever code is currently available. The beta channel allows you to see what’s next with minimal risk, although it is not fully supported by Google. There are two other channels: beta and developer. The stable channel is fully tested and supported by Google, and is the best to avoid crashes or other issues with your operating system. Your ChromeOS device is normally on a stable channel. Modifications and experimental features may cause hardware, software, or security issues.

Warning: Enabling experimental features of any kind are not supported by Google and may void your warranty.

Being on the cutting edge allows you to try out new features before they’re ready, letting you provide feedback to Google or modify your operating system more deeply than what’s otherwise available in the normal, stable ChromeOS release.
