As such, the fast ring will become the Dev Channel, the slow ring will become the Beta Channel and release preview will be called the Release Preview Channel. The new Dev Channel isn’t all that different from the fast ring — users will get access to new features as early as possible — however it won’t be tied to a specific release. Features will become available as soon as they’re ready. This obviously means things are liable to be a bit more unstable, so Microsoft says this channel is best suited to more advanced users.

The Beta Channel, meanwhile, gives access to the true beta version of a release and is meant for early adopters, while the Release Preview Channel remains essentially the same as the release preview ring — users can test reasonably stable builds before they get shipped. The changes are set to launch later this month, and will happen automatically if you’re already part of the Windows Insider program. You can change your channel, or start flighting, by going to Settings > Update & Security > Windows Insider Program, and choosing the channel that best fits your needs.
