Category	Description
Announcements	Announcements about unload event changes and WIP and MDAG retirement in Microsoft Edge.
Feature Updates	Updates to profile setup, third-party sign-in, and password details in Microsoft Edge.
Policy Updates	New and updated policies in Microsoft Edge.
Security	Stable channel security updates are listed here.

Announcements

• Deprecating the unload event. Microsoft Edge is changing the default behavior of the web platform unload event. As the rollout progresses, pages will no longer run unload event handlers unless the site explicitly permits them.

  • In Edge 152 and 153, unload handlers will stop firing by default for 60% of page loads unless the site explicitly enables them through Permissions Policy.

  • In Edge 155, the rollout will reach 100% of page loads.

Browsers and operating systems can suspend or terminate pages without firing it, and this can prevent pages from using the back/forward cache, which may make back and forward navigation slower.
