The Edge browser has been updated to version 93.0.961.44. This update to the Stable channel was released on September 11, 2021.
Though this is a Stable channel release, there don’t appear to be any noteworthy features in this update. Rather, it looks like it’s just for security fixes.
The Edge browser will automatically update itself the next time you close the browser window. However, if your browser is open, you can head to Settings > Help and Feedback > About Microsoft Edge, and then the browser will automatically check for new updates and apply them.
