Version 148.0.3967.54: May 07, 2026 (Stable)

Release Summary

Announcements

• Migration to improved V2 architecture for Workspaces. Workspaces, introduced in Edge in 2022, allows users to create durable sets of tabs that can be saved and shared with others. In order to improve reliability and performance of this feature, the following changes are being made:

  • Migrating data for saved Workspaces from OneDrive/SharePoint to Edge Sync service

  • Removing the collaboration/share functionality of this feature

  For organizations who have disabled Sync through policy, the existing v1 Workspace data will still be migrated to the new architecture. New v2 Workspaces created after migration won't sync across devices and will remain local to each device. This update occurs on a progressive rollout beginning in Edge Stable v145 and will continue rolling out in Edge v148. For more information, see Getting started with Microsoft Edge Workspaces.

• Microsoft 365 Copilot Chat. The Edge internal container page that hosts compliant M365 Copilot chat in the sidebar has been updated. Blocking internal edge:// or chrome-untrusted:// URLs isn't recommended as this may lead to unexpected errors and will disable the Microsoft 365 Sidebar Copilot Chat experience. For more information, see Allowlist for Microsoft Edge endpoints.

Feature Updates

• M365 Copilot Search relevance using work browsing history. With admin approval, Microsoft Edge can now send selected work-related browsing history from third-party apps to Microsoft 365 Copilot to improve search result ranking. When a user searches on Microsoft 365 Copilot Search, M365 Copilot will also surface results from work browsing history when relevant, helping users find recently visited work pages faster. Admins can control availability of this feature using the ShareBrowsingHistoryWithCopilotSearchAllowed policy.

• Password affiliation service. Password autofill suggestions in Edge are currently based on top-level domain matching, which means the same credentials can be suggested on sites like account.microsoft.com and office.microsoft.com. With this feature, Edge groups related domains together across various desktop and mobile properties called affiliations. When a customer visits a URL, the Edge client queries the affiliations backend to obtain "affiliated groups" for that URL. The process involves sending a hash of the visited URLs to the service, which then returns a list of affiliated URLs and ensures that the relevant credentials will be displayed in the autofill suggestions across affiliated domains. Admins must use both the PasswordManagerEnabled and PrimaryPasswordSetting policies together to control access to this feature. Configuring both policies allow admins to ensure no passwords get saved, lookups for autofill are disabled and affiliation endpoint won't be queried.

• Copilot New Tab Page. Search, chat, and explore the web from one search box with Copilot suggested actions and curated work content to help your users get things done faster on the new, refreshed Copilot New Tab Page. Users can also view personalized news and activities. Admins can control availability to this feature using the CopilotNewTabPageEnabled policy. For more information, see Configure the Copilot new tab page.

• Shadow AI. Currently admins can set Purview DLP policies to protect sensitive data from being sent to any Generative AI apps, users get blocked from sending their prompts to LLM when this is triggered and stops their workflow. This new add-on to the feature shows a new UI that will give users the option to be redirected to M365 Copilot, which will open and navigate to this M365 Copilot tab and allow them to send the same prompt there.

• Enhanced Autofill. For desktop users, Microsoft Edge can now autofill additional document types-including passports, driver's licenses, and other specialized forms-on top of your saved addresses. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

• Allow M365 authentication popups in work profiles. When users are signed in with a work account, some Microsoft 365 sites (for example, microsoft.com, cloud.microsoft, and microsoft365.com) may open authentication pop-up windows to Microsoft sign-in endpoints such as login.microsoftonline.com, login.live.com, or login.microsoft.com. These pop-ups are required to complete sign-in. Microsoft Edge now allows authentication pop-up windows from Microsoft first-party services by default. Admins can control availability to this feature using the M365AuthPopupsInWorkEnabled policy. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

• Updated AI settings page. Settings for Copilot features now are housed under one AI settings page to create a cohesive setting experience. Existing admin controls and policy configurations continue to apply.

To keep saved content, users can export it, or move all pages to Favorites. For more information, see Organize your ideas with Collections in Microsoft Edge - Microsoft Support.

• Migration to improved V2 architecture for Workspaces. Workspaces, introduced in Edge in 2022, allows users to create durable sets of tabs that can be saved and shared with others. In order to improve reliability and performance of this feature, the following changes are being made:

  • Migrating data for saved Workspaces from OneDrive/SharePoint to Edge Sync service

• Custom primary password deprecation. Users will no longer be able to create a new custom primary password in Edge Settings edge://settings/autofill/passwords/settings. Users who already have a custom primary password configured will see a warning that the feature won't be available from June 4, 2026. On June 4, 2026, any users who are still using a custom primary password will be automatically migrated to device authentication. Additionally, the PrimaryPasswordSetting policy will no longer support the WithCustomPrimaryPassword option.

Feature Updates

• Clarify choices surrounding third-party cookie settings. Language under Settings > Privacy, search, and services > Cookies are clarified to better describe the choices users have in managing third-party cookies. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

• Extensions monitoring in the Edge management service. The Microsoft Edge management service now allows admins to gain visibility into extensions installed across their managed users. From the extensions monitoring page, admins can see which extensions have been installed as well as manage user requests for blocked extensions. Note: This experience is in public preview and can be accessed by opting in to targeted release in the Microsoft 365 admin center. For more information, see Microsoft Edge Extensions Monitoring.

• Add setting to create or remove profile desktop shortcut for Windows. A new toggle is added in the profile settings to give users the ability to create or remove the profile desktop shortcut. Available only for Windows devices. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.

• Copilot New Tab Page. Search, chat, and explore the web from one search box with Copilot suggested actions and curated work content to help your users get things done faster on the new, refreshed Copilot New Tab Page.

Note: This experience is in public preview and can be enabled via the Edge management service inside the Microsoft 365 Admin Center. The release timeline has been updated, and general availability is now expected in early May. For more information, see Configuring Copilot Features | Microsoft Learn..

• Validate Edge builds early with enterprise preview. Enterprise preview provides a simpler way for admins to flight pre-release Edge builds to their users. To reduce friction and bolster usage, users receive pre-release builds directly inside of their Stable Edge application. Admins can allow users to easily opt-out of the preview experience, using built-in rollback to switch between their pre-release and stable channels with ease. Microsoft 365 admin center users can configure the feature, view their flighting population, and receive personalized recommendations all in one place. Note: Part of this experience is in public preview and can be accessed by opting in to targeted release in the Microsoft 365 admin center. For more information, see Get started with Enterprise Preview in Microsoft Edge.

• Expanded Microsoft Purview Information Protection (MIP) support for Microsoft 365 Online. Microsoft Purview Information Protection enables data loss prevention (DLP) controls in Microsoft 365 documents by limiting or preventing certain actions on documents with specific sensitivity levels. When administrators enable Microsoft Purview Information Protection in the Edge management service, the policy enforces secure enterprise browser access for Microsoft Word, Excel, and PowerPoint. Starting in Edge version 147, support is also available for Outlook on the web (OWA). For more information, see Protect Office documents with Microsoft Purview Information Protection labeling.

• Copilot integration in Immersive Reader. Immersive Reader improves reading accessibility by simplifying webpages and removing visual distractions. When using Immersive Reader, users can now Summarize, Explain, and Chat with Copilot directly through the Immersive Reader toolbar. Available on Windows devices.

Release Summary

Version 147.0.3912.86: April 24, 2026 (Stable)

Release Summary

Feature Updates

• Cross Tenant Support using Intune MAM. Edge for Business extends its capability to deliver Intune App Protection Policies via Intune MAM. Organizations are enabled to apply data loss prevention controls to Edge for Business profiles even on devices managed by another tenant. This capability enforces Intune MAM policies-such as clipboard boundaries, watermarking, and protected downloads-within the Edge work profile, ensuring sensitive data remains governed by your tenant. When enabled, downloads initiated in Edge are redirected to OneDrive for Business instead of local storage, and leak controls for screenshots and DevTools activate when data protection settings are applied. This approach secures cross-tenant scenarios like contractors or mergers without requiring additional apps or disrupting the end user experience. For more information, see Cross-tenant support using Intune MAM.

Fixes

• Fixed an issue where some policies requiring a domain-joined or MDM-managed device incorrectly displayed the error message "This policy is blocked, its value is ignored."
