Dev Channel updates

The following Dev channel updates preceded this Stable channel release. The following Dev notes provide detailed information about the changes in each release.

Fixes

Feature updates

  • Update to Microsoft Edge supported operating systems. The minimum supported macOS version is increased to macOS 11. Users on older versions of macOS will no longer receive Microsoft Edge updates. For more information, see Microsoft Edge Supported Operating Systems.

  • Deprecation of the CryptoWallet feature. To improve end user experience, the CryptoWallet feature and the CryptoWalletEnabled policy is deprecated. The CryptoWalletEnabled policy will be obsolete in an upcoming release.

Site compatibility impacting changes

  • Deprecation of non-standard declarative shadow DOM serialization. The prototype implementation, which shipped in 2020 and then updated in 2023, contained a method called getInnerHTML() that could be used to serialize DOM trees containing shadow roots. That part of the prototype wasn't standardized with the rest of the declarative shadow DOM, and has only recently reached spec consensus (for details, see GitHub. As part of that consensus, the shape of the getInnerHTML API changed.

  • Deprecate the includeShadowRoots argument on DOMParser. The includeShadowRoots argument was a never-standardized argument to the DOMParser.parseFromString() function, which was there to allow imperative parsing of HTML content that contains declarative shadow DOM. This function was shipped as part of the initial shipment of declarative shadow DOM. Since the standards discussion rematerialized in 2023, the shape of DSD APIs changed, including this feature for imperative parsing.

    Now that a standardized version of this API, in the form of setHTMLUnsafe() and parseHTMLUnsafe() shipped, the non-standard includeShadowRoots argument needs to be deprecated and removed. All usage should shift accordingly:

    Instead of:

    (new DOMParser()).parseFromString(html,'text/html',{includeShadowRoots: true});

    This can be used instead:

    document.parseHTMLUnsafe(html);

  • Rename inset-area to position-area. The CSS working group (CSSWG) resolved to rename this property from inset-area to position-area. For more information, see the CSSWG discussion in GitHub.

    The old and new property names are supported for a few milestones, to help developers migrate to the new position-area name. We're shipping the new property name, position-area, as a synonym for inset-area.

    The inset-area property is currently planned for removal in Microsoft Edge version 131.

Dev Channel updates

The following Dev channel updates preceded this Stable channel release. The following Dev notes provide detailed information about the changes in each release.

Fixes

  • Fixed an issue that caused high CPU usage of renderer processes when running Selenium tests and calling driver.quit() to end the testing session.

Feature updates

  • SSE3 Requirement. Microsoft Edge stopped supporting CPUs that lack SSE3. Devices with such CPUs won't receive any more updates. For more information, see Microsoft Edge Supported Operating Systems.

  • Copilot browser Context Policies. The DiscoverPageContextEnabled policy is obsoleted in Microsoft Edge version 128 and doesn't work after Microsoft Edge 127.

    To summarize and answer questions based on browser context in Microsoft Edge, Copilot needs to be able to access the browser context. We're providing two new policies to offer more flexibility for admins to customize Edge browser context access across Copilot chats in Edge sidebar.

    • CopilotPageContext - Control Copilot access to browser context for Microsoft Entra ID profiles.
    • CopilotCDPPageContext - Control Copilot with Commercial Data Protection access to browser context for Microsoft Entra ID profiles.

  • Deprecation of the followable web feature. To improve end user experience, the followable web feature is deprecated. The EdgeFollowEnabled policy is also obsolete.

  • EnforceLocalAnchorConstraintsEnabled policy obsoletion. The EnforceLocalAnchorConstraintsEnabled policy was previously deprecated and is now obsolete in Edge version 128. Since Microsoft Edge 112, constraints in certificates loaded from the platform certificate store are enforced. The EnforceLocalAnchorConstraintsEnabled policy existed as a temporary opt-out in case an enterprise encountered issues with the constraints encoded in their private roots.

  • New Policy for Insecure Downloads over HTTP. Users that download potentially dangerous content on HTTP sites will receive a UI warning in a future Microsoft Edge version. To prepare for this change, the ShowDownloadsInsecureWarningsEnabled policy is now available for admins to enable or disable the warnings related to insecure downloads

  • Edge Bar improvements. Edge Bar, the detachable version of the Edge sidebar in Windows 10, has a changed entry point from the gear icon at the bottom of the Edge sidebar's fly out menu to the edge://settings/sidebar page.

    For Windows 11 and Windows 10 users, clicking the gear icon will now automatically open the edge://settings/sidebar page.

    Also, the ability for Edge Bar to start automatically when starting a Windows 10 device has been enabled again, the Close "X" icon has been moved below the ellipsis menu at the bottom right corner of Edge Bar, and Copilot in Edge will remain within the browser not in Edge Bar. Note: These features are a controlled feature rollout. If you don't see these features, check back as we continue our rollout.

    Disabling Edge Bar through the StandaloneHubsSidebarEnabled policy continues to work, there's a fix to make the UI and briefcase icon appear on the edge://settings/sidebar page coming soon.

This branding can help users signed in with a Microsoft Entra ID more easily differentiate between multiple profiles and browser windows through visual cues on the profile pill, profile flyout, and Edge for Business taskbar icon.

    This Microsoft Edge management service feature gives admins an enhanced experience to configure, preview, and customize how Edge for Business shows the following organization brand assets:

    • Organization name
    • Accent color
    • Organization logo

Dev Channel updates

The following Dev channel updates preceded this Stable channel release. The following Dev notes provide detailed information about the changes in each release.

Improved reliability

  • Fixed a browser crash that happened when using the Microsoft Edge Password Generator.

Fixes

  • Updated HttpAllowlist policy. Automatic HTTPS should now respect the HttpAllowlist policy, which provides a list of hostnames that HTTP should be permitted on.

  • Resolved issue. Fixed an issue that prevented the Translate icon in the omnibox from being clickable.

Announcement

  • SSE3 Requirement. Microsoft Edge will stop supporting CPUs that lack SSE3 in Microsoft Edge 128. Devices with such CPUs won't receive any more updates. For more information, see Microsoft Edge Supported Operating Systems.

  • Token Binding. Token Binding uses cryptographic certificates on both ends of the TLS connection in an attempt to close the security gap of bearer tokens, which might be lost or stolen. We're planning to deprecate Token Binding in Microsoft Edge version 130. The AllowTokenBindingForUrls policy is deprecated and will be obsolete in Microsoft Edge version 130.

Feature updates

  • Removal of mutation events. Support for mutation events was removed. The MutationObserver API can be used instead. Administrators can use the MutationEventsEnabled policy as a temporary workaround. Enterprises should still work to remove their dependencies on these mutation events. For more information, see Intent to Ship: Deprecate Mutation Events (google.com).

  • Gift Card Redemption History in the Hub. Users with an MSA or Microsoft Entra ID Linked Account can view and utilize information from gift card redemptions through Pay with Rewards or the Rewards Dashboard. Once a user successfully redeems a gift card with Pay with Rewards, information relating to their gift card (date, card number/pin, redemption status) redemption is added to a Redemption History. This information is located in the Wallet hub. Admins can control availability of this feature using the EdgeWalletCheckoutEnabled policy. Note: This feature is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

  • Password Monitor policy update. When the PasswordMonitorAllowed policy is enabled as mandatory, users won't see the consent screen to turn on the feature. Also, when set to Mandatory enabled, the UI in Settings will be disabled but remain in the 'On' state, and a briefcase icon is made visible next to it with this description displayed on hover - "This setting is managed by your organization." For more information, see Password Monitor auto-enabled for users.
