+#### Crash Reporting key-value API
+
+The Crash Reporting key-value API lets your app attach custom key-value metadata to browser crash reports.
+
+Use this API to include diagnostic context, such as the current app state or feature flags, to help investigate crash patterns.

+<!-- ------------------------------ -->
+#### Reduced User-Agent strings by default
+
+User-Agent reduction is now enabled by default.  This further reduces passive fingerprinting surface, by limiting high-entropy data in the User-Agent string.
+
+If your app relies on browser details, use Client Hints instead of parsing the User-Agent string.
+

+
+<!-- ------------------------------ -->
+#### Trusted Types aligned with spec
+
+The Trusted Types implementation is now aligned with the latest specification updates.
+
+This improves interoperability, and strengthens defenses against DOM XSS by enforcing safer handling of HTML, script, and script URL injection sinks.

-#### IDNA ContextJ rules
-
-To improve interoperability with other browsers, Microsoft Edge now implements the IDNA ContextJ rules, by disallowing ZWNJ (U+200C ZERO WIDTH NON-JOINER) and ZWJ (U+200D ZERO WIDTH JOINER) characters in most places within URLs.
-
-IDNA is the mechanism by which non-ASCII characters can occur in domain names.  For example, the URL `http://네이버.한국/` is encoded as `http://xn--950bt9s8xi.xn--3e0b707e/`.

-
-The behavior of `border-width`, `outline-width`, and `column-rule-width` properties has been updated to align with the latest CSS specifications.
-
-Previously, if the corresponding `border-style`, `outline-style`, or `column-rule-style` property was set to `none` or `hidden`, the computed width would be forced to `0px`, regardless of the value that you specified.

+The Largest Contentful Paint (LCP) algorithm now emits candidates based on painted content.  This aligns the algorithm with the latest behavior per the specification.

+
+
+<!-- ====================================================================== -->
+## CSS features
+
+The following new Cascading Style Sheets (CSS) features are included in Microsoft Edge.
+
+
+<!-- ------------------------------ -->
+#### `border-shape`
+
+The `border-shape` property lets you create non-rectangular borders using any arbitrary shape, such as polygons, circles, or custom paths.
+
+Unlike `clip-path`, which clips the entire element, `border-shape` defines the shape of the border itself, decorates it, and only clips the element's content.  You can either stroke a shape or fill between two shapes.
+
+See also:
+* [Border Shaping](https://drafts.csswg.org/css-borders-4/#border-shape) in _CSS Borders and Box Decorations Module Level 4_.
+
+
+<!-- ------------------------------ -->
+#### `contrast-color()`
+
+The `contrast-color()` function automatically returns either black or white, depending on which provides the highest contrast against a given color.
+
+Use this function to meet accessibility contrast requirements easily.  You can use `contrast-color()` anywhere in CSS where a color value is expected.
+
+See also:
+* [contrast-color()](https://developer.mozilla.org/docs/Web/CSS/Reference/Values/color_value/contrast-color) at MDN.
+
+
+<!-- ------------------------------ -->
+#### CSS `*-width` properties are now independent of `*-style` properties
+
+The behavior of `border-width`, `outline-width`, and `column-rule-width` properties has been updated to align with the latest CSS specifications.
+
+Previously, if the `border-style`, `outline-style`, or `column-rule-style` property was set to `none` or `hidden`, the corresponding computed `border-width`, `outline-width`, or `column-rule-width` would be forced to `0px`, regardless of the value that you specified.
+
+Now, the computed values of `border-width`, `outline-width`, and `column-rule-width` always reflect your specified values, independently of the corresponding `*-style` property.

+* [column-rule-width](https://developer.mozilla.org/docs/Web/CSS/Reference/Properties/column-rule-width) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Animation timelines support a `"scroll"` range
+
+In scroll-driven animations, view timelines now support a `"scroll"` named range, in addition to the existing named ranges.
+
+The supported named ranges are now:
+* `"contain"`
+* `"cover"`
+* `"entry"`
+* `"exit"`
+* `"scroll"`
+
+The new `"scroll"` range refers to the full extent of the scroll container, rather than only the portion of the scroll container in which the animation subject is visible.  This gives you more control over when animations start and stop, within the scrollable area.
+
+See also:
+* [animation-range](https://developer.mozilla.org/docs/Web/CSS/Reference/Properties/animation-range) at MDN.
+
+
+<!-- ------------------------------ -->
+#### `accent-color: auto` now only applies to installed web apps
+
+The `accent-color: auto` CSS property, also known as system accent color, is now scoped to only work within installed Progressive Web Apps (PWAs), not within webpages displayed in the browser.  This aligns with the existing `AccentColor` and `AccentColorText` CSS system color keywords.
+
+Previously, when `accent-color` was set to `auto`, form controls would adopt the system accent color in all webpages, whether they're displayed in the browser or in an installed PWA.
+
+This change provides a more consistent developer experience and user experience, while adhering to fingerprinting restrictions.
+
+See also:
+* [accent-color](https://developer.mozilla.org/docs/Web/CSS/Reference/Properties/accent-color) at MDN.

+The `<textPath>` SVG element now supports a `path` attribute.  Use the `path` attribute to define text path geometry inline, by using SVG path data.
+
+Instead of always needing to reference a separate `<path>` element by using the `href` attribute, you can now include the path data directly in the `<textPath>` element's `path` attribute.
+
+When both `path` and `href` are specified, the `path` attribute takes precedence.

+
+<!-- ====================================================================== -->
+## Web APIs
+
+The following new Web API features are included in Microsoft Edge.
+
+
+<!-- ------------------------------ -->
+#### Clear the `window.name` value for cross-site navigations that switch browsing context group
+
+The `window.name` property is now cleared when a cross-site navigation switches browsing context groups.
+
+Previously, the value of the `window.name` property was preserved throughout the lifetime of a browser tab, even when a cross-site navigation switched browsing context groups.
+
+See also:
+* [Window: name property](https://developer.mozilla.org/docs/Web/API/Window/name) at MDN.
+* [Browsing context](https://developer.mozilla.org/docs/Glossary/Browsing_context) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Device Bound Session Credentials
+
+Device Bound Session Credentials (DBSC) provides a way to bind session credentials to a specific device, making stolen session cookies harder to reuse.
+
+This improves account security for signed-in sessions, and helps reduce session hijacking risks.
+
+See also:
+* [Device Bound Session Credentials](https://w3c.github.io/webappsec-dbsc/)
+
+
+<!-- ------------------------------ -->
+#### Web App Origin Migration
+
+Web App Origin Migration enables a Progressive Web App (PWA) to migrate to a new origin while preserving trust, install state, and applicable permissions.
+
+This helps teams safely move apps across domains without forcing users to reinstall.
+
+See also:
+* [Web App Manifest](https://developer.mozilla.org/docs/Web/Manifest) at MDN.
+
+
+<!-- ------------------------------ -->
+#### OpaqueRange
+
+`OpaqueRange` represents a live text range inside text controls such as `<input>` and `<textarea>`.
+
+Use `OpaqueRange` to enable range-based operations, including:
+* Geometry queries.
+* Integration with highlighting workflows.
+
+See also:
+* [Range](https://developer.mozilla.org/docs/Web/API/Range) at MDN.
+
+
+<!-- ------------------------------ -->
+#### `<install>` HTML element
+
+The `<install>` HTML element represents a button that, upon activation, prompts the user to choose whether to install a progressive web app. 
+
+The content and appearance of the install button is controlled by Microsoft Edge and provides users with a consistent experience across web apps.
+
+See also:
+* [User-Initiated Installation of a Web Application](https://github.com/WICG/install-element?tab=readme-ov-file#user-initiated-installation-of-a-web-application).
+* [Progressive web apps (PWAs)](https://developer.mozilla.org/docs/Web/Progressive_web_apps) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Connection allowlists
+
+Connection allowlists let apps declare and enforce explicit allowlists for network endpoints that can be contacted by web platform networking APIs.
+
+This improves outbound network control, and reduces the risk of unintended connections.
+
+See also:
+* [Fetch API](https://developer.mozilla.org/docs/Web/API/Fetch_API) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Autofill event
+
+Use the new `autofill` event to detect when browser autofill updates form controls.
+
+This makes it easier to adapt custom UI, validation, or dependent form logic after autofill completes.
+
+See also:
+* [HTMLElement: input event](https://developer.mozilla.org/docs/Web/API/Element/input_event) at MDN.
+
+
+<!-- ------------------------------ -->
+#### CSSPseudoElement interface
+
+The `CSSPseudoElement` interface represents pseudo-elements in the CSS Object Model.  The `CSSPseudoElement` interface is returned by `Element.pseudo(type)`, and supports nested pseudo-elements.
+
+This makes it easier to inspect and manipulate behavior that's related to pseudo-elements, in advanced styling scenarios.
+
+See also:
+* [Pseudo-elements](https://developer.mozilla.org/docs/Web/CSS/Pseudo-elements) at MDN.
+
+
+<!-- ------------------------------ -->
+#### `dropEffect` handling in drag-and-drop events
+
+When using the Drag and Drop API, the `dropEffect` attribute now has the correct predetermined values during `dragenter`, `dragover`, and `dragleave` events, as specified by the HTML standard.
+
+The `dropEffect` is now based on the current `effectAllowed` for `dragenter` and `dragover` events.  For `dragleave` events, `dropEffect` is always `"none"`.
+
+See also:
+* [HTML Drag and Drop API](https://developer.mozilla.org/docs/Web/API/HTML_Drag_and_Drop_API) at MDN.
+* [DataTransfer: dropEffect property](https://developer.mozilla.org/docs/Web/API/DataTransfer/dropEffect) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Element-scoped view transitions
+
+View transitions can now be scoped to individual HTML elements by using the `element.startViewTransition()` method.
+
+When a view transition is scoped to an element, the transition pseudo-elements are affected by ancestor clips and transforms.  Multiple transitions on separate elements can run concurrently, giving you more flexibility in creating complex animations.
+
+See also:
+* [View Transitions API](https://developer.mozilla.org/docs/Web/API/View_Transitions_API) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Detect Secure Payment Confirmation capabilities
+
+Use the `PaymentRequest.getSecurePaymentConfirmationCapabilities()` static method to determine which Secure Payment Confirmation features are supported in the browser.
+
+This async method returns an object that describes the browser's Secure Payment Confirmation capabilities.  Use the returned object to decide whether to use Secure Payment Confirmation features for your payment flow.
+
+See also:
+* [Using Secure Payment Confirmation](https://developer.mozilla.org/docs/Web/API/Payment_Request_API/Using_secure_payment_confirmation) at MDN.
+
+
+<!-- ------------------------------ -->
+#### IDNA ContextJ rules
+
+Microsoft Edge now implements the IDNA ContextJ rules, by disallowing the following characters in most places within URLs:
+
+* ZWNJ (U+200C ZERO WIDTH NON-JOINER)
+
+* ZWJ (U+200D ZERO WIDTH JOINER)
+
+This improves interoperability with other browsers.
+
+IDNA is the mechanism by which non-ASCII characters can occur in domain names.  For example, the URL `http://네이버.한국/` is encoded as `http://xn--950bt9s8xi.xn--3e0b707e/`.
+
+See also:
+* [Better Unicode support](./143.md#better-unicode-support) in _Microsoft Edge 143 web platform release notes (Dec. 2025)_.
+
+
+<!-- ------------------------------ -->
+#### `<link rel="modulepreload">` supports JSON and CSS modules
+
+You can now use `<link rel="modulepreload">` to preload JSON modules and CSS modules, in addition to JavaScript modules.
+
+Specify the module type by using the `as` attribute:
+
+* For CSS modules: `<link rel="modulepreload" as="style" href="...">`
+
+* For JSON modules: `<link rel="modulepreload" as="json" href="...">`
+
+This brings feature parity across different module types, for preloading.
+
+See also:
+* [rel="modulepreload"](https://developer.mozilla.org/docs/Web/HTML/Reference/Attributes/rel/modulepreload) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Local Network Access restrictions on Service Worker `WindowClient.navigate()`
+
+Local Network Access restrictions now apply to navigations that are initiated by Service Workers through `WindowClient.navigate()`.
+
+The `WindowClient` is used as the initiator of the navigation, to determine if the navigation is a Local Network Access request.  This only applies if the `WindowClient` being navigated is a subframe; Microsoft Edge doesn't enforce Local Network Access restrictions on main frame navigations.
+
+See also:
+* [WindowClient](https://developer.mozilla.org/docs/Web/API/WindowClient) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Local Network Access restrictions for WebSockets
+
+Local Network Access restrictions now apply to WebSocket connections to local addresses, which will trigger permission prompts.
+
+All current Local Network Access enterprise policies apply to WebSocket restrictions (`LocalNetworkAccessAllowedForUrls`, `LocalNetworkAccessBlockedForUrls`, and `LocalNetworkAccessRestrictionsTemporaryOptOut`).
+
+See also:
+* [New permission prompt for Local Network Access](https://developer.chrome.com/blog/local-network-access) on developer.chrome.com.
+
+
+<!-- ------------------------------ -->
+#### Local Network Access restrictions for WebTransport
+
+WebTransport requests to the user's local network are now restricted behind a permission prompt.
+
+A local network request is any request from a public website to a local IP address or loopback, or from a local website (such as an intranet) to loopback.  Gating these requests behind a permission reduces the ability of sites to fingerprint the user's local network.  This permission is restricted to secure contexts.
+
+See also:
+* [WebTransport](https://developer.mozilla.org/docs/Web/API/WebTransport) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Manifest localization
+
+Web app manifests now support localization.  This allows a web app to adapt its name, description, icons, and shortcuts to the user's language and region.
+
+When you provide localized values in the web app manifest, the browser automatically selects the appropriate resources based on the user's language settings.
+
+See also:
+* [Web app manifests](https://developer.mozilla.org/docs/Web/Manifest) at MDN.
+
+
+<!-- ------------------------------ -->
+#### `Math.sumPrecise`
+
+The new `Math.sumPrecise()` method returns the sum of values in an iterable item, using a more precise algorithm than naive summation.
+
+This method helps avoid floating-point precision errors when summing multiple numbers.
+
+See also:
+* [Math](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Math) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Pointer event suppression on drag start
+
+When a drag operation starts, the browser now sends `pointercancel`, `pointerout`, and `pointerleave` events to the drag source, to indicate that the pointer event stream has ended.
+
+This behavior ensures that the drag source doesn't expect any more events from this pointer during the drag operation.
+
+This behavior is now fully implemented across all platforms.
+
+See also:
+* [HTML Drag and Drop API](https://developer.mozilla.org/docs/Web/API/HTML_Drag_and_Drop_API) at MDN.
+* [Pointer events](https://developer.mozilla.org/docs/Web/API/Pointer_events) at MDN.
+
+
+<!-- ------------------------------ -->
+#### `pseudoTarget` property on events
+
+The `pseudoTarget` property is now available on `UIEvent`, `AnimationEvent`, and `TransitionEvent` objects.
+
+When an event originates from a pseudo-element, `pseudoTarget` returns a `CSSPseudoElement` object that represents that pseudo-element.  Otherwise, `pseudoTarget` is `null`.
+
+`Event.pseudoTarget` provides additional information about the origin of the event. The existing `Event.target` property remains unchanged.
+
+See also:
+* [Event.target](https://developer.mozilla.org/docs/Web/API/Event/target) at MDN.
+
+
+<!-- ------------------------------ -->
+#### `Request.isReloadNavigation` attribute
+
+The `isReloadNavigation` read-only boolean attribute is now available on the Fetch API's `Request` interface.
+
+The `isReloadNavigation` attribute indicates whether the current navigation request was initiated as a user-triggered reload, such as:
+* When the user clicks **Refresh** in the browser toolbar.
+* When the page calls the `location.reload()` or `history.go(0)` methods in response to a user interaction on the page.
+
+This signal is primarily exposed on the `Request` object that's within a Service Worker's `FetchEvent`.
+
+See also:
+* [Request](https://developer.mozilla.org/docs/Web/API/Request) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Respect `autocorrect="off"` for Windows touch keyboard
+
+The Windows touch keyboard now respects the `autocorrect="off"` attribute on editable elements, including `<input>`, `<textarea>`, and `contenteditable` hosts.
+
+Previously, the touch keyboard would autocorrect words even when `autocorrect="off"` was set.  Now, autocorrections are detected and reverted when the focused element has `autocorrect="off"`.
+
+See also:
+* [autocorrect](https://developer.mozilla.org/docs/Web/HTML/Reference/Global_attributes/autocorrect) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Device Memory API limits
+
+The Device Memory API now reports updated values that better reflect modern device capabilities:
+
+* Android devices: 1, 2, 4, or 8 GB
+
+* Other platforms: 2, 4, 8, 16, or 32 GB
+
+These new values replace the outdated values (0.25, 0.5, 1, 2, 4, 8 GB).  This reduces fingerprinting risk, and provides better segmentation for high-end devices.
+
+See also:
+* [Device Memory API](https://developer.mozilla.org/docs/Web/API/Device_Memory_API) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Web Serial API on Android
+
+The Web Serial API is now supported on Android, allowing a web app to connect to serial devices through a serial port, or through a removable USB or Bluetooth device that emulates a serial port.
+
+This is useful for educational, hobbyist, and industrial applications that need to control peripheral devices from a connected device.  Such peripheral devices include:
+* Robots.
+* Mills.
+* Laser cutters.
+* 3D printers.
+
+See also:
+* [Web Serial API](https://developer.mozilla.org/docs/Web/API/Web_Serial_API) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Always negotiate data channels in WebRTC
+
+Use the new `alwaysNegotiateDataChannels` option for `RTCPeerConnection` to negotiate data channels in the Session Description Protocol offer, before creating a data channel.
+
+When enabled:
+* The data channel `m=` line is placed before any audio or video `m=` lines.
+* When using `BUNDLE`, to reuse a single connection for multiple media types, the data channel `m=` line is used as the offerer tagged media section.
+
+See also:
+* [RTCPeerConnection](https://developer.mozilla.org/docs/Web/API/RTCPeerConnection) at MDN.
+
+
+<!-- ------------------------------ -->
+#### WebXR Layers
+
+WebXR Layers enables more efficient rendering of immersive experiences by delegating composition to the system compositor rather than JavaScript.
+
+Key benefits:
+
+* Layers are presented at the compositor's native refresh rate.
+* Composition layers are resampled only once, compared to twice in traditional WebXR rendering, resulting in better text and visual quality.
+* JavaScript and GPU commands run less frequently since the compositor handles resampling and reprojection.
+* The compositor always has the latest pose data and runs at high priority, reducing perceived latency.
+
+WebXR Layers supports multiple layer types including projection, quad, cylinder, equirectangular, and cube layers, along with native color, depth textures, and texture arrays.
+
+See also:
+* [WebXR Layers API Level 1](https://www.w3.org/TR/webxrlayers-1/)
+* [WebXR Layers samples](https://immersive-web.github.io/webxr-samples/layers-samples/)
+
+
+<!-- ------------------------------ -->
+#### WebXR Plane Detection
+
+The WebXR Plane Detection API allows sites to retrieve the set of planes that's detected in the user's environment.
+
+Plane detection provides more powerful capabilities than depth-sensing.
+
+* Planes, such as walls that are occluded by objects, can still be fully represented, if the system is aware of the boundaries of the wall.
+
+* Semantic labeling information is also exposed where available, allowing better knowledge about the environment.
+
+See also:
+* [WebXR Device API](https://developer.mozilla.org/docs/Web/API/WebXR_Device_API) at MDN.
+
+
+<!-- ------------------------------ -->
+#### XML parsing in Rust for non-XSLT scenarios
+
+Microsoft Edge now uses a Rust-based XML parser, in scenarios where XSLT processing isn't required.
+
+The Rust XML parser improves security by eliminating memory-corruption bugs in XML parsing.  This applies to:
+* The DOMParser Web API.
+* `responseXML` of `XMLHttpRequest`.
+* SVG documents.
+
+See also:
+* [DOMParser](https://developer.mozilla.org/docs/Web/API/DOMParser) at MDN.
+
+
+<!-- ====================================================================== -->
+## Deprecated or removed features
+
+
+<!-- ------------------------------ -->
+#### Remove inline XSLT for production of SVG
+
+Support for using XSLT stylesheets to transform XML data into SVG files has been removed.
+
+Previously, a specially crafted XML file could contain an XSL stylesheet that transforms generic XML data into an SVG file.  This capability is now deprecated and has been removed. 
+

+#### Enhanced Canvas TextMetrics
+
+Expires on Aug. 11, 2026.
+
+The Enhanced Canvas TextMetrics origin trial expands the TextMetrics Canvas API to support:
+* Selection rectangles.
+* Bounding-box queries.
+* Operations based on a glyph cluster.
+
+This new functionality enables complex text-editing applications to have accurate selection, caret positioning, and hit-testing.
+
+Also, cluster-based rendering facilitates sophisticated text effects, such as:
+* Independent character animations.
+* Independent character styling.

+#### `focusgroup` HTML attribute for keyboard navigation
+
+Expires on Aug. 11, 2026.
+
+Standardize keyboard navigation for composite widgets such as toolbars, tabs, menus, and radio groups, by using the `focusgroup` HTML attribute.
+
+The `focusgroup` attribute automatically handles the following, without requiring custom JavaScript code:
+* The _roving tabindex_ behavior.
+* Navigation via arrow keys.
+* Focus memory (restores the last-focused element when re-entering the focusgroup).

+
+`prerender_until_script` is a new action for the Speculation Rules API.  This new action provides a middle option in between the `prefetch` and the `prerender` actions.
+
+Use the `prerender_until_script` action when you want the browser to prerender a page, but stop and switch back to prefetching after a specific script starts executing.

 | Insecure downloads over HTTP | Future release (TBD) | When a user tries to download potentially dangerous content from an HTTP site, the user will receive a UI warning, such as "Insecure download blocked."  The user will still have an option to proceed and download the item.  Admins can use the `InsecureContentAllowedForUrls` policy to specify HTTP sites for which the warning will be suppressed.  Admins can use the `InsecureDownloadWarnings` feature flag to test the impact of this upcoming feature. |
 | Deprecate unload event | Future release (TBD) | Introduces a new Permission-Policy to allow creating unload event listeners. The default policy is `allow`, but the default policy will gradually be migrated to `deny`, such that unload handlers stop firing on pages, unless a page explicitly opts in to re-enable them.  This change is happening in the Chromium project, on which Microsoft Edge is based.

 | Removal of Token Binding support | v127, v130 | Token Binding uses cryptographic certificates on both ends of the TLS connection in an attempt to close the security gap of bearer tokens, which may be lost or stolen.  The enterprise policy [AllowTokenBindingsForUrls](/deployedge/microsoft-edge-policies#allowtokenbindingforurls) will no longer be supported, as of v127.  Support for the Token Binding protocol will be removed in v130. |
