When Microsoft first released the public previews of its Chromium-powered Edge browser a couple of weeks ago, it introduced three branches: Canary, Dev, and Beta. Canary gets daily updates, and Dev should get weekly builds - the first of which arrived today. For those wondering, builds for the Beta channel are coming soon, and that will be updated every six weeks.
If you're on Edge Dev, you'll now find the browser on version 188.8.131.52, a major upgrade from 184.108.40.206. In fact, it's just a small update away from the Canary branch, which is on 220.127.116.11.
There are a few things to be aware of in this build. Media casting is now available. You can go to 'More tools' and 'Cast media to device' to turn this on. There are also still some known issues, such as those with Chrome extensions that require you to sign into a Google account, and those that require a companion app on your PC. Spellchecking is not yet available, and you can't sync with a work or school account.
Other key features are still listed as coming soon. These include dark mode, accessibility improvements, grammar tools, smooth scrolling, reading view, translation, and inking.
