On 17 August 2020, Microsoft announced that it will end support for Internet Explorer 11 across all of its Microsoft 365 apps, which includes OneDrive, Outlook, and more. The announced date is 9 March 2021 for the legacy version of Edge to be removed from Windows 10 computers in favor of the new Chromium-based Microsoft Edge.

This also means that after this date, Microsoft Edge Legacy will no longer receive security updates. According to a Microsoft 365 blog post, the new Microsoft Edge “will be available as part of the Windows 10 cumulative monthly security update” and will be released on 13 April 2021.

“The new Microsoft Edge offers built-in security and works with the Microsoft security ecosystem to help customers realize a holistic approach to security,” wrote the Microsoft Edge Team.

Microsoft first unveiled its new Edge browser back in 2015 under the codename “Project Spartan”. Users who have already installed the Chromium version of Edge on their PCs will just have the legacy one automatically removed once the new update rolls in.
