Fixed various bugs and performance issues, and feature updates.
Deprecation of Microsoft Edge Support page. To improve end user experience, edge://support is being deprecated. The information found on edge://support is available on other pages: edge://version, edge://metrics-internals, edge://extensions, and edge://policy.
AI theme generator. Microsoft Edge includes an AI theme generator that allows users to input a text string and generate a series of images to preview as browser themes. Applying the theme includes setting the generated image on the Edge new tab page and applying the image's dominant color to the browser frame. Users can now find a new entry point in edge://settings/appearance which will direct them to AI Theme Generator: Create a Custom Browser Theme. Admins can control availability to this feature using the AIGenThemesEnabled policy. If an admin chooses to disable the feature via policy, the page linked in Edge Settings will be available, but users won't be allowed to generate images and they'll see an error message. Note: This is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
Fixed various bugs and performance issues, Dev channel updates, feature updates, policy updates, and site compatibility impacting changes.
The following Dev channel updates preceded this Beta channel release. These notes provide detailed information about the changes in each release.
Intune policies in the Microsoft Edge management service. Admins now can set Intune policies via the Microsoft Edge management service, alongside the existing cloud policies. This ability lets admins deploy both browser policies in the cloud and Intune policies from a single pane, making it easy to keep users safe and the browser workflow streamlined. This feature comes along with a new policy creation wizard that streamlines the creation process into a comprehensive, step-by-step flow. Note: This experience is in public preview and can be accessed by opting in to targeted release in the Microsoft 365 admin center.
Version monitoring in the Edge management service. The Edge management service offers a single view of all managed Edge instances with their update status and possible actions to take. For out-of-date devices, you can easily schedule updates or notify users to update their browsers to avoid workflow interruptions. Note: This experience is in public preview and can be accessed by opting in to targeted release in the Microsoft 365 admin center.
Shopping Product Tracking. Track product prices easily with a new experience in the Edge Address Bar that appears on the product detail page. Users can track prices quickly and are notified when there's a price drop on that product and save more. Administrators can control the availability of Shopping in Edge using the EdgeShoppingAssistantEnabled policy. Note: This feature is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
Feature Usage Data Sync. Edge Sync, which enables users to synchronize their Edge user data across multiple devices, is now launching a new sync data category called Feature Usage. This new category allows users to synchronize data regarding their utilization of Edge features across all their devices. Note: This feature is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
New password manager policy. The DeletingUndecryptablePasswordsEnabled policy controls whether the built-in password manager can delete undecryptable passwords from its database. This policy is required to restore the full functionality of the built-in password manager, but it might cause permanent data loss. Undecryptable password values won't become decryptable on their own. If fixing them is possible, it usually requires complex user actions.
PromotionalTabsEnabled policy deprecation. The PromotionalTabsEnabled policy is deprecated in Microsoft Edge version 132 and will be obsolete in a future Microsoft Edge version. Administrators can use the ShowRecommendationsEnabled policy instead.
Allow enterprise users to view XFA PDFs using IE Mode. Enterprise customers can view XFA PDFs in Microsoft Edge using IE mode through either the ViewXFAPDFInIEModeAllowedOrigins or ViewXFAPDFInIEModeAllowedFileHash policy. This change will be available in the new PDF viewer on Microsoft Edge.
AdHocCodeSigningForPWAsEnabled - Native application signing during Progressive Web Application installation
AutomaticFullscreenAllowedForUrls - Allow automatic full screen on specified sites
AutomaticFullscreenBlockedForUrls - Block automatic full screen on specified sites
CreatePasskeysInICloudKeychain - Control whether passkey creation will default to iCloud Keychain
DeletingUndecryptablePasswordsEnabled - Enable deleting undecryptable passwords
GenAILocalFoundationalModelSettings - Settings for GenAI local foundational model
IPv6ReachabilityOverrideEnabled - Enable IPv6 reachability check override
LiveTranslationAllowed - Live translation allowed
PersonalizeTopSitesInCustomizeSidebarEnabled - Personalize my top sites in Customize Sidebar enabled by default
ViewXFAPDFInIEModeAllowedFileHash- View XFA-based PDF files using IE Mode for allowed file hash.
ViewXFAPDFInIEModeAllowedOrigins - View XFA-based PDF files using IE Mode for allowed file origin.
SelectParserRelaxationEnabled - Controls whether the new HTML parser behavior for the <select>
element is enabled
Note
Portions of this release note are modifications based on work created and shared by Chromium.org and used according to terms described in the Creative Commons Attribution 4.0 International License.
CSS Anchor Positioning: allow anchor-size()
in inset and margin properties. Originally, anchor-size()
was only allowed in sizing properties. The specification now allows anchor-size()
in insets and margins as well.
CSS sideways writing modes. Support of sideways-rl
and sideways-lr
keywords for the writing-mode
CSS property. sideways-rl
and sideways-lr
are helpful to write non-CJK text vertically. They don't have behaviors favorable for CJK languages unlike vertical-rl
and vertical-lr
.
Dialog toggle events. This change incorporates the same ToggleEvent
that popovers dispatch, but for <dialog>
elements: when showModal
or show
is called, <dialog>
dispatches a ToggleEvent
with newState=open
. When a <dialog>
is closed (using the form, button, or closewatcher) it should dispatch a ToggleEvent
with newState=closed
.
Previously, to detect when a <dialog>
opens a mutation observer had to be registered to check for open.
Element Capture. Given a video MediaStreamTrack
obtained through pre-existing means to initiate tab-capture, Element Capture allows mutating the track to only capture a subtree of the DOM starting at a given Element.
The API bears some resemblance to the Region Capture API, but affords greater flexibility for applications, because occluding and occluded content are both excluded from the capture.
FedCM authorization features. This bundles a few features that Identity Providers (IdP) can use to implement authorization flows such as letting a user grant access to their calendar to a Relying Party (RP). Specifically:
FedCM Mode API and Use Other Account API. Two new extensions for FedCM:
active
mode allows websites to call FedCM inside a button click (for example, selecting a Sign-in to IdP button), which requires FedCM to guarantee it always responds with a visible user interface. Calling the FedCM API in active mode takes users to sign in to the Identity Provider (IdP) when users are logged-out. Also, because the active mode is called within an explicit user gesture, the UI is also more prominent (for example, centered and modal) compared to the UI from the passive mode (which doesn't require a user gesture requirement and can be called on page load).Fetch: Request.bytes()
and Response.bytes()
. Add a bytes()
method to the Request
and Response
interfaces, which returns a promise that resolves with a Uint8Array. While Request
and Response
have an arrayBuffer()
method, it’s not possible to read directly from a buffer. A view such as a Uint8Array
must be created to read it. The bytes()
method improves the ergonomics of getting the body of Request and Response.
Ignore Strict-Transport-Security for localhost. Strict-Transport-Security
(STS) response headers can cause problems for localhost web servers because STS applies host-wide, across all ports. This causes compatibility problems for web developers testing locally. It also affects end-users who use software packages that commonly start localhost web servers for ephemeral reasons. For example, communication of an auth token from a web sign-in to a local software package. If one local listener sets Strict-Transport-Security
on a localhost response, it's applied to all subsequent localhost requests regardless of port.
Edge 132 resolves this problem by ignoring Strict-Transport-Security
headers on responses from localhost URLs.
Keyboard focusable scroll containers. The rollout of this feature (from Edge 130) was stopped due to an accessibility regression. This issue is fixed and the feature continues to rollout with Edge 132. KeyboardFocusableScrollersEnabled is the policy for this feature.
Private State Token API Permissions Policy default allowlist wildcard. Access to the Private State Token API is gated by Permissions Policy features. Edge 132 updates the default allowlist for both private-state-token-issuance
and private-state-token-redemption
features from self
to *
(wildcard).
PushMessageData::bytes()
. The PushMessageData
interface mimics the Body
interface, which was amended earlier this year with a new bytes()
method, following the principle that APIs should generally vend byte buffers as Uint8Arrays
. Edge 132 realigns with the Body
interface by providing the bytes()
accessor on the PushMessageData
interface as well.
Saved queries in sharedStorage.selectURL
. sharedStorage.selectURL()
now lets queries to be saved and reused on a per-page basis. Two per-page-load budgets are charged the first time a saved query is run but not for subsequent runs of the saved query during the same page-load. This change is accomplished with a savedQuery
parameter in the options for selectURL()
that names the query.
Throw exception for popovers and dialogs in non-active documents. Previously calling showPopover()
or showModal()
on a popover or dialog that resides within an inactive document would silently fail. No exception was thrown, but since the document is inactive, no popover or dialog would be shown. As of Edge 132, these situations now throw InvalidStateError
.
WebAuthn Signal API. Allows WebAuthn relying parties to signal information about existing credentials back to credential storage providers, so that incorrect or revoked credentials can be updated or removed from provider and system UI.
WebGPU: 32-bit float textures blending. The float32-blendable
GPU feature makes GPU textures with formats r32float
, rg32float
, and rgba32float
blendable.
WebGPU: Expose GPUAdapterInfo from GPUDevice. The GPUDevice adapterInfo
attribute exposes the same GPUAdapterInfo
as the GPUAdapter
object.
WebGPU: Texture view usage. Adds an optional field to WebGPU texture view creation to request a subset of the usage flags from the source texture.
By default, texture view usage inherits from the source texture but there are view formats that can be incompatible with the full set of inherited usages. Adding a usage field to texture view creation allows the user request a subset of the source texture's usages that are valid with the view format and specific to their intended usage of the texture view.
WebGPU implementations can also optimize the creation of low level resources and improve performance when using views with more specialized usage flags.
New origin trials: Document-Isolation-Policy. The Document-Isolation-Policy lets a document enable crossOriginIsolation
for itself, without having to deploy COOP or COEP, and regardless of the crossOriginIsolation
status of the page. The policy is backed by process isolation. Additionally, the document non-CORS cross-origin subresources will either be loaded without credentials or will need to have a CORP header.
New origin trials: Explicit Compile Hints with Magic Comments. This feature lets you attach information about which functions should be eager parsed and compiled in JavaScript files. The information will be encoded as magic comments.
navigator.storage
no longer an EventTarget. navigator.storage
was made an EventTarget
for the Storage Pressure Event, which never made it past the prototype phase. This dead code is being removed and as a result, navigator.storage
will no longer extend EventTarget
.
Remove Prefixed HTMLVideoElement Fullscreen APIs. The prefixed HTMLVideoElement fullscreen APIs have been deprecated from Edge.
They were replaced by the Element.requestFullscreen()
API. As of 2024, most browsers have had support for the unprefixed APIs for a few years now.
Edge 132 removes the following from HTMLVideoElement
:
webkitSupportsFullscreen
attribute.webkitDisplayingFullscreen
attribute.webkitEnterFullscreen()
method.webkitExitFullscreen()
method. Note the different capitalization of the "S" in FullScreen.webkitEnterFullScreen()
method.webkitExitFullScreen()
method.These methods are now only aliases for the modern API. Their use has declined steadily over the years.

Changes to Kyber. The Kyber algorithm was standardized with minor technical changes and renamed to the Module Lattice Key Encapsulation Mechanism (ML-KEM). ML-KEM is implemented in the BoringSSL cryptography library, which allows for it to be deployed and utilized by services that depend on this library.
The changes to the final version of ML-KEM make it incompatible with the previously deployed version of Kyber. Due to this incompatibility the following changes in Microsoft Edge will be made:
PostQuantumKeyAgreementEnabled
flag and the PostQuantumKeyAgreementEnabled policy applies to Kyber and ML-KEM.Fixed various bugs and performance issues.

The following Dev channel updates preceded this Beta channel release. These notes provide detailed information about the changes in each release.
Cancel dialog for beforeunload
event. Microsoft Edge changed the behavior of the cancel dialog for the beforeunload
event. Calling event.preventDefault
in a beforeunload
event handler won't prevent the dialog from being shown. Instead, event.returnValue = ''
needs to be called in the beforeunload
event handler to prevent the cancel dialog. The BeforeunloadEventCancelByPreventDefaultEnabled policy is obsolete and no longer works after Microsoft Edge version 130.
Get the latest updates effortlessly with instant update. Instant update in Microsoft Edge ensures you get the latest browser updates automatically, when you step away from your computer. You can keep browsing, knowing that you already have the latest updates to keep you safe online. For more information, see Get instant updates in Microsoft Edge - Microsoft Support. Note: This feature is in private preview for enterprise customers. Future feature updates are available via Microsoft Edge release notes.
CSS Anchor Positioning: anchor-scope
. The anchor-scope
property allows limiting the visibility of anchor names to a given subtree.
CSS font-variant-emoji
. The font-variant-emoji
CSS property provides a way to control between colored (emoji-style) and monochromatic (text-style) emoji glyphs. This method can be also done by adding an emoji Variation Selector, specifically U+FE0E for text and U+FE0F for emoji, after each emoji codepoint.
CSS highlight inheritance. With CSS highlight inheritance, the CSS highlight pseudo-classes, such as ::selection
and ::highlight
, inherit their properties through the pseudo highlight chain, rather than the element chain. The result is a more intuitive model for inheritance of properties in highlights.
Improvements to styling structure of <details>
and <summary>
elements. Support more CSS styling for the structure of <details>
and <summary>
elements to allow these elements to be used in more cases where disclosure widgets or accordion widgets are built on the web. In particular, this change removes restrictions that prevented setting the display property on these elements, and adds a ::details-content
pseudo-element to style the container for the part that expands and collapses.
@page
margin boxes. Add support for page margin boxes, when printing a web document, or exporting it as PDF.
The @page
margin boxes let you define the contents in the margin area of a page, for example to provide custom headers and footers, rather than using the built-in headers and footers generated by the browser.
A margin box is defined using an at-rule inside a CSS @page
rule. The appearance and the contents of a margin box are specified with CSS properties inside the @page
rule, including the content
property. Counters are also supported, for page numbering. The specification defines two special counter names: page
for the current page number and pages
for the total number of pages.
@property support <string>
syntax. Support for <string>
syntax component name for registered custom properties.
Support currentcolor
in relative color syntax. Allow relative colors in CSS (using the from
keyword) to use currentcolor
as a base. This support lets you set complementary colors, based on an element's text color, for that element's borders, shadows, or backgrounds.
This feature also includes use cases where color functions are nested with a dependency on currentcolor
, for example: color-mix (in srgb, rgb(from currentcolor r g b), white)) or rgb(from rgb(from currentcolor 1 g b) b g r)
.
Support external SVG resources for clip-path
, fill
, stroke
, and marker-*
properties. This feature adds support for external references for clip paths, markers, and paint servers (for the fill
and stroke
properties). For example, clip-path: url("resources.svg#myPath")
.
Direct Sockets API. Allows Isolated Web Apps to establish direct transmission control protocol (TCP) and user datagram protocol (UDP) communications with network devices and systems as well as listen to and accept incoming connections.
Exempt Speculation-Rules
header from CSP restrictions. Updates the integration between speculation rules and CSP so that CSP only applies to <script type=speculationrules>
, and not to the Speculation-Rules
header. CSP's script policies are meant to protect against injection of scripts into HTML, and the CSP threat model doesn't relate to HTTP headers. This approach allows easier deployment of speculation rules from CDNs and other edge servers.
FedCM as a trust signal for the Storage Access API. Reconciles the FedCM and Storage Access APIs by making a prior FedCM grant a valid reason to automatically approve a storage access request.
When a user grants permission to use their identity with a third-party identity provider (IdP) on a relying party (RP), many IdPs require third-party cookies to function correctly and securely. This proposal aims to satisfy that requirement in a private and secure manner by updating the Storage Access API (SAA) permission checks to not only accept the permission grant given by a storage access prompt, but also the permission grant given by a FedCM prompt.
A key property of this mechanism is limiting the grant to cases explicitly allowed by the RP with the FedCM permissions policy, enforcing a per-frame control for the RP and preventing passive surveillance by the IdP beyond the capabilities that FedCM already grants.
COOP value noopener-allow-popups
. Some origins can contain different applications with different levels of security requirements. In those cases, it can be beneficial to prevent scripts running in one application from being able to open and script pages of another same-origin application.
In such cases, it can be beneficial for a document to ensure its opener can't script it, even if the opener document is a same-origin one. The noopener-allow-popups
Cross-Origin-Opener-Policy value lets documents define that behavior.
Select parser relaxation. This change makes the HTML parser allow more tags in <select>
besides <option>
, <optgroup>
, and <hr>
.
This change is in support of the customizable <select>
feature but is being shipped first because it can be done separately and has some compat risk.
WebGPU: Clip distances. Adds the optional GPU feature clip-distances
that allows setting user-defined clip distances in vertex shader outputs. This technique is useful for the applications that need to clip all vertices in a scene that are beyond a user-defined plane, such as many CAD applications.
WebGPU: GPUCanvasContext getConfiguration()
. Once GPUCanvasContext configure()
is called with a configuration dictionary, the GPUCanvasContext getConfiguration()
method can be used to check the canvas context configuration. It includes GPU device
, format
, usage
, viewFormats
, colorSpace
, toneMapping
, and alphaMode
members. As discussed in issue 4828, web apps can use it to detect whether HDR canvas is supported in WebGPU.
WebHID on dedicated workers. Enables WebHID inside dedicated worker contexts. This lets the performance of heavy I/O and processing of data from a HID device on a separate thread, helping to reduce the performance impact on the main thread.
WebRTC RTCRtpEncodingParameters.scaleResolutionDownTo
. An API that configures WebRTC encoders to scale input frames if they're greater than the specified maxWidth
and maxHeight
. This API is similar to scaleResolutionDownBy
except that resolution constraints are expressed in absolute terms (for example, 640x360) as opposed to relative terms (for example, scale down by 2), avoiding race conditions related to changing input frame size on the fly.
Remove the CSS Anchor Positioning property inset-area
. With the CSS Working Group resolution on renaming the inset-area
property to position-area
, this removal cleans up the implementation for a standards compliant feature.
Remove non-standard GPUAdapter requestAdapterInfo()
method. The WebGPU Working Group decided it was impractical for requestAdapterInfo()
to trigger a permission prompt so they've removed that option and replaced it with the GPUAdapter info
attribute so that web developers can get the same GPUAdapterInfo
value synchronously.

beforeunload
event in Microsoft Edge version 131. Starting in version 131, calling event.preventDefault
in a beforeunload
event handler won't prevent the dialog from being shown. Instead, event.returnValue = ''
needs to be called in the beforeunload
event handler to prevent the cancel dialog. The BeforeunloadEventCancelByPreventDefaultEnabled policy is being obsoleted and will no longer work after Microsoft Edge version 130.Fixed various bugs and performance issues, feature updates, and policy updates.

The following Dev channel updates preceded this Beta channel release. These notes provide detailed information about the changes in each release.
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 may be lost or stolen. Token Binding is deprecated in Microsoft Edge version 130. Also, the AllowTokenBindingForUrls policy is now obsolete.
Edge on macOS now seamlessly opens links in Teams. When you set the default browser to Microsoft Edge on macOS and enable the feature, web links from the Teams desktop app are sent via chats, channels, calendar, and other entry points. These links seamlessly open automatically in the profile signed into Teams app and skips the need to reauthenticate in the browser. This feature makes it faster and easier to access content. Administrators can control the availability of this feature using the "Choose Which Browser Opens Web Links" Microsoft 365 policy. Note: This feature is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
Elevating top settings and improving settings page navigability. To make finding browser settings more efficient, Microsoft Edge is introducing three navigation improvements to Edge Settings. We aren’t changing the functionality of any setting, and all the settings stay on the same page as they are today but will be behind clickable sections. These changes are as follows.
Introduce quick access to the most used Settings actions on the first place users land when entering Edge Settings (the Profiles page). Clicking the button with the name of the setting navigates users directly to its location.
Make densely populated Settings pages (such as Privacy, search, and services, Appearance, Cookies and site permissions, System and performance) easier to navigate by introducing quick access to the most used actions located on that page. Clicking the button with the name of the setting takes users directly to its location.
For these densely populated pages, each lengthy section of settings will be a clickable "table of contents" with descriptive subtexts. This helps users locate settings directly and avoid unnecessary scrolling.
Note: This feature is a controlled feature rollout. If you don't see this feature, check back as we continue our rollout.
CSS Container Queries flat tree lookup. The specification for container queries changed to look up flat tree ancestors. This change is only relevant for shadow DOM where an element will now be able to see non-named containers inside shadow trees into which the element or one of its ancestors is slotted, even if the CSS rule doesn't use ::part()
or ::slotted()
.
CSS Nesting: The nested declarations rule. Keeps bare declarations following a nested rule in their place, by wrapping those declarations in CSSNestedDeclarations
rules during parsing.
Full and unprefixed box-decoration-break support. Adds support for box-decoration-break:clone
both for inline fragmentation (line layout) and block fragmentation (pagination for printing and multicol).
Previously, only box-decoration-break:slice
(the initial value) was supported for block fragmentation, whereas for inline fragmentation, box-decoration-break:clone
was also supported, but only when using the prefixed -webkit-box-decoration-break
property.
Allow more pseudo-elements and pseudo-classes after ::part(). CSS selectors that use the ::part()
pseudo-element are allowed to have other CSS pseudo-elements (except ::part()
) and many types of other CSS pseudo-classes after them. Combinators are still not allowed after ::part()
, and pseudo-classes that depend on tree structure aren't allowed.
Previously only a limited set of pseudo-classes and pseudo-elements after ::part()
was allowed. This change allows all of the pseudo-classes and pseudo-elements that should be allowed. It means selectors such as ::part(part-name):enabled
and ::part(part-name)::marker
are now allowed.
Compression dictionary transport with shared Brotli and shared Zstandard. This feature adds support for using designated previous responses, as an external dictionary for content encoding compressing responses with Brotli or Zstandard.
Enterprises might experience potential compatibility issues with enterprise network infrastructure that intercepts HTTPS traffic and is sensitive to unknown content encodings. The enterprise policy CompressionDictionaryTransportEnabled is available to turn off the compression dictionary transport feature.
Concurrent smooth scrollIntoView(). The scrollIntoView() method with behavior: "smooth" lets developers create scroll containers that scroll to their descendants with a gentle scroll animation. This feature fixes the implementation of the API so that ongoing scrollIntoView animations aren't canceled by unrelated scrolls on other scroll containers.
The feature also fixes cases where Edge fails to scroll to a page's fragment anchor because of a competing scrollIntoView that is invoked when the page loads.
Document picture-in-picture: add option to ignore window bounds cache. This change adds a new parameter (preferInitialWindowPlacement
) to the document picture-in-picture API that, when set to true, hints to the user agent that it shouldn't try to reuse the position or size of the previous document picture-in-picture from this site when opening this one.
Often, a document picture-in-picture window closes and reopens multiple times for the same site, such as moving a video conference to and from PiP. The user agent is free to reopen the PiP window at its most recent size and location, so that it stays where the user last moved it and provides continuity between the PiP windows. However, if the new window is semantically unrelated to the previous window, such as if it's a new video call, then the developer can use this parameter to provide a hint to the user agent that this window might be better opened in its default position and size instead.
Improved error reporting in IndexedDB for large value read failures. Change to reporting for certain error cases that were previously reported with a DOMException and the message "Failed to read large IndexedDB value."
Now a DOMException is raised with the name "NotFoundError" when the file containing the data being read by an IDBRequest is missing from the disk so that sites can take the appropriate corrective action when an unrecoverable failure occurs. Corrective actions could include deleting the entry from the DB, notifying the user, or re-fetching the data from servers.
Keyboard focusable scroll containers. This feature makes scrollers without focusable children keyboard-focusable by default.
This is an important improvement to help make scrollers and contents within scrollers more accessible to all users. Keyboard focusable scrollers are enabled by default starting in version 130.
If more time is needed to implement this feature, the KeyboardFocusableScrollersEnabled policy is available starting with Edge 128.
Support non-special scheme URLs. Previously, the URL parser didn't support non-special URLs. The parser parses non-special URLs as if they had an "opaque path," which isn't aligned with the URL Standard. Now, the URL parser parses non-special URLs correctly, following the URL Standard.
See bit.ly/url-non-special for more details.
WebAssembly JavaScript String Builtins. This feature exposes common JavaScript string operations for import into WebAssembly. This lets you create and manipulate JavaScript strings from WebAssembly without support within WebAssembly. This still allows for a similar performance as supported string references.
WebGPU: Dual source blending. Adds the optional GPU feature "dual-source-blending" that enables combining two fragment shader outputs into a single framebuffer. This technique is useful for applications that require complex blending operations, such as those based on Porter-Duff blend modes. By reducing the need for frequent pipeline state object changes, dual source blending can enhance performance and flexibility.
Web Serial: connected attribute and RFCOMM connection events. This feature adds a boolean SerialPort.connected
attribute. The attribute returns true if the serial port is logically connected. For wired serial ports, a port is logically connected if the port is physically attached to the system. For wireless serial ports, a port is logically connected if the device hosting the port has any open connections to the host.
Previously, only wired serial ports dispatched connect and disconnect events. With this feature, Bluetooth RFCOMM serial ports dispatch these events when the port becomes logically connected or disconnected.
This feature is intended to allow applications to detect when a Bluetooth RFCOMM serial port is available without opening the port.
Remove expectedImprovement in DelegatedInkTrailPresenter. The expectedImprovement attribute tells web developers how much improvement the DelegatedInkTrails API will provide to their current ink latency. However, this attribute isn't worth the increase to fingerprinting entropy.
Deprecate non-standard GPUAdapter requestAdapterInfo() method. The requestAdapterInfo()
asynchronous method in WebGPU is redundant because developers can already get GPUAdapterInfo synchronously using the GPUAdapter info attribute.
