Microsoft has been changing things up with how it tests new features internally and through its Insider Program. For the past several months, the builds that were being released to the Fast ring (now called the Dev Channel) weren't tied to any specific version of the operating system.

This changes today as Microsoft has announced Windows 10 version 20H2, releasing builds to the Beta Channel (previously known as the Slow ring). "The 20H2 feature update will be a scoped set of features and include the new Microsoft Edge based on Chromium," the company wrote in today's announcement.
