Microsoft has released the first Dev and Canary channel builds of the next version of Microsoft Edge, which is based on the Chromium open source project. The company last year revealed that it was reworking its Edge browser to be based on Chromium. Now the latest developments are ready for early testers and adopters on several versions of Windows and macOS. So far, however, no support is available for Linux. The new Microsoft Edge builds are available through preview channels called "Microsoft Edge Insider Channels."
