Microsoft today launched the first beta builds of its new, Chromium-based Edge browser for Windows and Mac. The new beta channel, which will see a new update roughly every six weeks, will join the existing dev and canary channels, which will continue to see daily and weekly updates, respectively.

Over the course of the last few months of preview releases in the existing channels, Microsoft gathered about 140,000 pieces of feedback. With this — and a sufficient amount of telemetry it also received from early adopters — the company now feels that it knows enough about how well Edge works on a wide range of machines and that it is stable enough for enthusiasts, web developers and business users to give it a try before its wider release.
