-#### Always negotiate data channels in WebRTC
-
-The new `alwaysNegotiateDataChannels` option for `RTCPeerConnection` allows you to negotiate data channels in the SDP offer before creating a data channel.  The data channel m-line is placed before any audio or video m-lines.
-
-Use this option when creating a peer connection, to ensure that data channels are always negotiated:
-
-```javascript
-const pc = new RTCPeerConnection({
-  alwaysNegotiateDataChannels: true
-});
-const offer = await pc.createOffer();

-
-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.

+-->
+
+
+<!-- ====================================================================== -->
+## CSS features
+
+The following new Cascading Style Sheets (CSS) features are included in Microsoft Edge.
+
+
+<!-- ------------------------------ -->
+#### CSS name-only container queries
+
+A CSS query container can be queried based on its `container-name` only, and the container doesn't need any `container-type` set:
+
+```html
+<style>
+#container {
+  container-name: --foo;
+}
+@container --foo {
+  input { background-color: green; }
+}
+</style>
+<div id="container">
+  <div><input></div>
+</div>
+```
+
+Previously, `@container` required some query in addition to the `container-name`.
+
+See also:
+* [@container](https://developer.mozilla.org/docs/Web/CSS/Reference/At-rules/@container) at MDN.
+* [container-name](https://developer.mozilla.org/docs/Web/CSS/Reference/Properties/container-name) at MDN.
+
+
+<!-- ------------------------------ -->
+#### The `revert-rule` keyword
+
+The `revert-rule` keyword rolls back the cascade to the previous rule.
+
+This is similar to how `revert-layer` rolls back the cascade to the previous _layer_.
+
+For example:
+
+```css
+div { color: green; }
+div { color: revert-rule; /* Effectively green */ }
+```
+
+The `revert-rule` keyword is especially useful in combination with conditionals.  The `revert-rule` keyword allows eliminating the current rule if some condition is not met:
+
+```css
+div {
+  display: if(style(--layout: fancy): grid; else: revert-rule);
+}
+```
+
+See also:
+* [The revert-rule keyword](https://drafts.csswg.org/css-cascade-6/#revert-rule) in _CSS Cascading and Inheritance Level 6_.
+
+
+<!-- ------------------------------ -->
+#### `at-rule()`: CSS feature detection
+
+The `at-rule()` function can be used in CSS `@supports`, to feature-detect support for CSS at-rules.
+
+See also:
+* [Extensions to the @supports rule](https://drafts.csswg.org/css-conditional-5/#at-supports-ext) in _CSS Conditional Rules Module Level 5_.
+
+
+<!-- ------------------------------ -->
+#### `text-decoration-skip-ink: all`
+
+The `text-decoration-skip-ink` property now has an `all` value.  This property continues to support `auto` and `none`.
+
+* `all` - Unconditionally applies ink-skipping to all glyphs, including CJK characters.  When using `text-decoration-skip-ink: all`, if you adjust `text-underline-position` or `text-underline-offset` to avoid clashing with CJK glyphs, you can explicitly opt in to ink-skipping for those characters as well.
+
+* `auto` - Keeps CJK characters un-skipped.  Useful for ideographic scripts.  Ink-skipping can produce undesirable visual results for ideographic scripts, at typical underline positions.
+
+* `none` - Prevents ink-skipping.
+
+See also:
+* [text-decoration-skip-ink](https://developer.mozilla.org/docs/Web/CSS/Reference/Properties/text-decoration-skip-ink) at MDN.
+* [The text-decoration-skip-ink property](https://drafts.csswg.org/css-text-decor-4/#text-decoration-skip-ink-property) in _CSS Text Decoration Module Level 4_.
+
+
+<!-- ====================================================================== -->
+## Web APIs
+
+The following new Web API features are included in Microsoft Edge.
+
+
+<!-- ------------------------------ -->
+#### Content type in Resource Timing
+
+The new `contentType` field on `PerformanceResourceTiming` holds a string that corresponds to the content type of the fetched resource, as returned by the server.
+
+See also:
+* [PerformanceResourceTiming: contentType property](https://developer.mozilla.org/docs/Web/API/PerformanceResourceTiming/contentType) 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.
+
+For `dragenter` and `dragover` events, the `dropEffect` attribute is now based on the current `effectAllowed`.
+
+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.
+
+
+<!-- ------------------------------ -->
+#### Extended lifetime shared workers
+
+Set the `extendedLifetime` option when creating a shared worker, to keep the service worker alive for a bounded time after all client pages close.  This technique enables reliable completion of async operations during unload.
+
+See also:
+* [SharedWorker](https://developer.mozilla.org/docs/Web/API/SharedWorker) at MDN.
+
+
+<!-- ------------------------------ -->
+#### Detect Secure Payment Confirmation capabilities
+
+Use the `PaymentRequest.getSecurePaymentConfirmationCapabilities()` method to determine which Secure Payment Confirmation features are supported in the browser.
+
+This 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.
+
+This is an async, static method.
+
+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)_.
+
+
+<!-- ------------------------------ -->
+#### Lazy loading for video and audio elements
+
+Use the new `loading` attribute of `<video>` and `<audio>` elements, with a value of `lazy`, to defer media resource loading until the element is near the viewport.
+
+Syntax:
+
+```html
+<audio loading="lazy"/>
+<video loading="lazy"/>
+```
+
+This matches the existing lazy loading behavior for `<img>` and `<iframe>` elements, improving page load performance and reducing data usage.
+
+See also:
+* [loading](https://developer.mozilla.org/docs/Web/HTML/Reference/Elements/video#loading) in _`<video>`: The Video Embed element_ at MDN.
+* [loading](https://developer.mozilla.org/docs/Web/HTML/Reference/Elements/audio#loading) in _`<audio>`: The Embed Audio element_ at MDN.

+* [loading](https://developer.mozilla.org/docs/Web/HTML/Reference/Elements/iframe) in _`<iframe>`: The Inline Frame element_ at MDN.
+
+
+<!-- ------------------------------ -->
+#### Manifest localization
+
+You can now localize manifest members, to adapt your PWA name, description, icon, and shortcuts to the user's language and region.
+
+You provide localized values in the web app manifest JSON file.  The browser then automatically selects the appropriate resources based on the user's language settings.

+#### Support for avar2 in OpenType font format
+
+Version 2 of the axis variations table (avar2) in the OpenType font format is now supported.
+
+Avar2 enables designers of fonts to create fonts with better control over interpolation. With avar2, the axes of variation in a font can influence one another, allowing for more complex designs, easier-to-use fonts, and smaller file sizes.

+#### 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.

+#### Prompt API
+
+The Prompt API provides direct access to a browser-provided on-device AI language model.
+
+The API design offers fine-grained control for progressively enhancing sites with model interactions tailored to individualized use cases.
+
+This complements task-based language model APIs (such as the Summarizer API) and varied APIs and frameworks for generalized on-device inference with developer-supplied ML models.
+
+The initial implementation supports text, image, and audio inputs, as well as response constraints that ensure generated text conforms with predefined regex and JSON schema formats.
+
+Use for:
+
+* Generating image captions.
+
+* Performing visual searches.
+
+* Transcribing audio.
+
+* Classifying sound events.
+
+* Generating text by following specific instructions.
+
+* Extracting information or insights from multimodal source material.

+
+<!-- ------------------------------ -->
+#### Reuse `no-store` images when same `src` is reassigned
+
+When you reassign the same `src` value to an `<img>` element, the browser now reuses the already-decoded image from the document, even if the image was served with `Cache-Control: no-store`.  This avoids an unnecessary network re-fetch and improves performance.
+
+Previously, the browser would re-fetch the image, even though the image was already decoded and available in the document.
+
+This web interoperability fix aligns Microsoft Edge with Firefox and Safari.
+
+See also:
+* [\<img\>: The Image Embed element](https://developer.mozilla.org/docs/Web/HTML/Reference/Elements/img) at MDN.

+
+
+<!-- ------------------------------ -->
+#### Web Authentication Immediate UI mode
+
+Most sign-in experiences on the web require a sign-in page that offers multiple options, such as username/password fields, federated sign-in buttons, and passkey buttons.  When the browser already knows about passkeys or passwords for a site, the Web Authentication Immediate UI mode can make the sign-in page unnecessary.
+
+The Immediate UI mode is a new mode for `navigator.credentials.get()`.  If the browser has a passkey or password for the site, the browser displays a sign-in UI to the user.  If no matching credential is available, the promise is rejected with `NotAllowedError` and no browser UI is shown, so the user's sign-in experience falls back to the site's traditional sign-in page.
+
+This reduces sign-in friction and avoids user confusion from having to remember which sign-in option they previously used on a given site.

+#### WebGPU `linear_indexing` feature
+
+The `linear_indexing` feature adds two new compute shader built-in values to the WebGPU Shading Language (WGSL):
+
+* `global_invocation_index`, a linearized version of `global_invocation_id`.
+* `workgroup_index`, a linearized version of `workgroup_id`.
+
+These built-in values provide a convenient single-dimensional index for compute shader invocations, replacing manual linearization that is easy to get wrong.

+
+
+<!-- ------------------------------ -->
+#### WebSocket disconnection on bfcache entry
+
+Open WebSocket connections are now closed when a page enters the back/forward cache (bfcache), instead of preventing the page from being cached.
+
+Previously, a page with an active WebSocket connection couldn't be stored in the bfcache.  With this change, more pages benefit from instant backward and forward navigation.
+
+Your page receives a `close` event on each affected `WebSocket` when the page enters the bfcache.  Listen for the `pageshow` event, and then reconnect when `event.persisted` is `true`.

+#### Always negotiate data channels in WebRTC
+
+Use the new `alwaysNegotiateDataChannels` option for a WebRTC `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.

 | 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.

 | 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.  For more information, see [Intent to Deprecate: Deprecate unload event](https://groups.google.com/a/chromium.org/g/blink-dev/c/dvusqw9-IhI/m/SBkm_u1RAQAJ). |
+| Deprecation of XSLT | Future release (TBD) | XSLT support represents a disproportionate attack surface, and the Chromium project which Microsoft Edge is based on has announced plans to disable and ultimately remove XSLT in a future release. See [Removing XSLT for a more secure browser](https://developer.chrome.com/docs/web-platform/deprecating-xslt). As a result, you should treat reliance on client‑side XSLT as technical debt and plan migration accordingly. Microsoft Edge version 147 introduces the XSLTEnabled feature policy to support testing and transition scenarios while the Chromium project works toward deprecating and removing XSLT support. We encourage organizations to proactively test setting `XSLTEnabled = Disabled` to identify application dependencies and remediation requirements ahead of any future default changes or removal of the feature. |
