Microsoft's switch to using the Chromium engine to power its Edge browser was announced in December last year, and the first public preview build is out now. Canary builds, updated daily, and Dev builds, updated weekly, are available for Windows 10. Versions for other operating systems and a beta that's updated every six weeks are promised to be coming soon.

Chromium is the open source browser project run by Google. It includes the Blink rendering engine (Google's fork of Apple's WebKit), V8 JavaScript engine, Google's software-based sandboxing, and the browser user interface. Google builds on Chromium for its Chrome browser, and a number of third-party browsers, including Opera, Vivaldi, and Brave, also use Chromium.
