Microsoft is pausing the releases of new major versions of the Edge browser, including version 81, to remain consistent with the Google Chrome releases, which were paused earlier this week. Google Chrome 81 was expected to be released to the Stable channel but was never released. Google will continue to provide new releases of Chrome 80 to fix security bugs that are discovered. Microsoft will continue releasing security and stability updates to Microsoft Edge 80. Preview channels (Canary, Dev, and Beta) will continue updates on their usual schedule.
