Microsoft is a contributor to the open source Chromium project, and has already delivered ' over 275 commits into the Chromium project' since December, according to Microsoft's second announcement. 'The Beta channel reflects a significantly more stable release and will be a good target for Enterprises and IT Pros to start piloting the next version of Microsoft Edge,' Microsoft explained in a second announcement. When the Beta Channel release of Edge becomes available, it'll be the one that Microsoft will recommend for organizations to follow. Users can provide feedback on the test releases via the F1 key, the smiley-face button or Twitter, according to this Microsoft Tech Community post.

Microsoft suggested that its test releases can work alongside current Edge browsers for Windows 10 without conflicts. They can just download a particular browser release to join the testing program, according to a Microsoft Tech Community post. Testers don't have to sign up for the program to use the Canary Channel or Dev Channel releases. There also will be a coming Beta Channel, where updates arrive every six weeks, and a coming Stable Channel.

The Canary and Dev Channels are both available now.

The Dev Channel gets updated weekly and represents the best that emerges from Canary releases. The Canary Channel gets updated daily and typically might contain more software flaws. Microsoft will have four separate 'channel' releases of the new Edge browser that testers can follow, although two are available now. Microsoft on Monday announced that early versions of its new Chromium-based Microsoft Edge browser for Windows 10 are now available for testing as part of the Microsoft Edge Insider testing program.
