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 154, the rollout will increase to 80% of page loads. In Edge 155, the rollout will reach 100% of page loads. The unload event is not a dependable way to save data, perform cleanup, or report the end of a session. 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. Web developers should migrate to lifecycle events and APIs designed for these scenarios. The long-term direction of the web platform is to remove support for unload. Microsoft Edge has completed the move to a 2-week cadence for updates. We have adopted a new, 2-week release cycle for major versions. Automatically unsubscribe users from notifications sent by scam and malicious sites. Microsoft Edge now helps further protect users from malicious web notifications. When a notification leads users to a site that Microsoft Defender SmartScreen blocks as a scam, phishing, or malware page, Edge automatically stops that source from sending users further notifications. Edge lets users know when this happens. Users can review and restore any of these sites anytime under edge://settings/privacy/sitePermissions/allPermissions/notifications. Sign in to Edge with an Apple account. Users can now sign in to Microsoft Edge using an Apple account in addition to the Microsoft account from the profile menu and Edge sign-in screen. Available for Windows and macOS devices. Admins can control availability to this feature using the NonMicrosoftAccountSignInEnabled policy. Real-time video translation retirement. Real-time video translation is being retired through a gradual rollout. Availability may vary across environments during the rollout. The LiveVideoTranslationEnabled policy will be deprecated in a future update. Enhanced Key Icon with Credential Details, Copy Actions, and Notes. The key icon in Edge's address bar now lets users click into any saved credential to view a detailed panel. From there, users can copy a username, reveal and copy a password, and add personal notes to each login. Keep track of security questions, account purpose, or recovery details right alongside credentials, without opening Settings or the full password manager. Drop is retired. We're simplifying Microsoft Edge. Drop is retired in Microsoft Edge version 152. New Copilot Cowork policy. Copilot Cowork may perform tasks such as creating tabs, taking screenshots, and interacting with web pages. Admins can now control availability of this feature using the CopilotCoworkToolActionsEnabled policy, which corresponds to the Allow Cowork to take actions on your behalf setting in edge://settings/ai. This policy applies only when Cowork Browsing is enabled at the tenant level in the M365 admin center. Clarification of WebView2 DowngradeVersion policy. The DowngradeVersion policy allows admins to temporarily roll back specific applications to a previous WebView2 Evergreen Runtime version (N-1 or N-2). The policy requires an exact 4-part numeric WebView2 Runtime version, for example 151.0.2178.0. Admins can find the exact 4-part version number in the Microsoft Edge release notes for Stable Channel. Major-version-only values are not supported. If no exact matching folder is found, the policy has no effect and the runtime defaults to the BrowserExecutableFolder policy or the Evergreen runtime, which is the default auto-updating runtime. Update for LocalNetworkAccessRestrictionsTemporaryOptOut policy. The planned removal of the LocalNetworkAccessRestrictionsTemporaryOptOut policy has been updated.
