CSS

CSS interpolate-size property and calc-size() function

The CSS interpolate-size property lets a page opt into animations and transitions of CSS intrinsic sizing keywords such as auto, min-content, and fit-content, in the cases where those keywords can be animated.

The CSS calc-size() function is a CSS function similar to calc(), however it also supports operations on exactly one supported sizing keyword. Supported sizing keywords are auto, min-content, max-content, and fit-content. Other sizing keywords that may be supported in the future include stretch (currently supported as prefixed -webkit-fill-available) and contain. This function is used to represent the values in the middle of the animations allowed by the interpolate-size property.

Update CSS backdrop-filter to use mirror edgeMode

The backdrop-filter CSS property applies one or more filters to the backdrop of an element. The backdrop is the painted content that lies behind the element. A common filter is a blur allowing designers to construct "frosted glass" dialog boxes, video overlays, translucent navigation headers, and more.

This was initially implemented the same way as a regular blur, but sampling beyond the edges of the element allowed colors from the edges to bleed in. The spec was changed to sample pixels outside the backdrop edges by duplicating the pixels at the edge. This however, results in extreme flickering of content as it enters the backdrop edge. The latest specification change mirrors the backdrop when sampling beyond the edge which allows for a smooth gradual introduction of new colors at the edges without overweighting on single lines of color.

Media

Blob support in WebRTC data channels

Implements RTCDataChannel.send(Blob), and the onMessage event can now optionally receive data of type Blob using the binaryType attribute.

In addition to supporting sending strings and ArrayBuffers, you can now choose to send a Blob instead as long as its size is below the SCTP transport maxMessageSize as indicated in the WebRTC specification.

Using the binaryType attribute set to blob, the onMessage event data attribute will be of type Blob instead of ArrayBuffer.

Web APIs

Private Aggregation API: client-side contribution merging

Modifies the Private Aggregation API to merge histogram contributions with the same bucket and filtering ID before embedding in the aggregatable report's encrypted payload.

Private Aggregation imposes a limit on the number of contributions that can be embedded in a single aggregatable report, with any additional contributions being dropped. By merging together contributions where possible, we can get additional utility out of the limit. Note that, ignoring the dropping of excess contributions, merging these sorts of contributions shouldn't have any impact on the final outputs, for example summary reports.

scheduler.yield()

Provides a method for yielding control to the browser, which can be used to break up long tasks. Awaiting the promise returned by scheduler.yield() causes the current task to yield, continuing in a new browser task. This can be used to improve responsiveness issues caused by long tasks. Continuations are prioritized to mitigate performance problems of existing alternatives.

Web Authentication API: JSON serialization methods

The WebAuthn PublicKeyCredential.toJSON(), parseCreationOptionsFromJSON(), and parseRequestOptionsFromJSON() methods let developers serialize a WebAuthn response into a JSON object or deserialize a WebAuthn request object from its JSON representation.

Rendering and graphics

WebGPU extended range (HDR) support

Adds tone mapping parameters to the WebGPU canvas configuration, and adds options of standard (the current behavior of restricting content to the SDR range of the display) as the default, and extended (not imposing this restriction) as a new behavior. This allows WebGPU content to use the full range of a display.

Origin trials

FileSystemObserver interface

The FileSystemObserver interface notifies websites of changes to the file system. Sites observe changes to files and directories in the user's local device (as specified in WICG/file-system-access) or in the Bucket File System (as specified in whatwg/fs), and are notified of basic change info, such as the change type.

Mesh2D Canvas API

A high-performance Canvas 2D triangle mesh API that can be used to batch-render a large number of textured triangles.

This will enable advanced texture mapping and geometry deformation effects in a 2D context.

Deprecations and removals

Deprecate 0.0.0.0 for Private Network Access

Chrome will block access to IP address 0.0.0.0 in advance of Private Network Access (PNA) completely rolling out.

Chrome is deprecating direct access to private network endpoints from public websites as part of the PNA specification. Services listening on localhost (127.0.0.0/8) are considered private according to the specification. Chrome's PNA protection can be bypassed using the IP address 0.0.0.0 to access services listening on the localhost on macOS and Linux.

This can also be abused in DNS rebinding attacks targeting a web application listening on the localhost.

This release of Chrome removes three features.

Remove 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 was shipped in Chrome 90 as part of the initial shipment of declarative shadow DOM.

Now that a standardized version of this feature is available with the setHTMLUnsafe() and parseHTMLUnsafe() methods, the non-standard includeShadowRoots argument will be removed. Code should be updated as follows:

Remove non-standard declarative shadow DOM serialization

The prototype implementation of declarative shadow DOM contained a method called getInnerHTML() used to serialize DOM trees containing shadow roots. That part of the prototype was not standardized with the rest of declarative shadow dom, and instead a replacement was designed—getHTML().

Therefore the old getInnerHTML() method is now being removed from Chrome, you should use getHTML() as a replacement, which will soon be interoperable across browsers.

Remove PointerEvent.getCoalescedEvents() from insecure contexts

The Pointer Events Working Group made PointerEvent.getCoalescedEvents() restricted to secure contexts over four years ago, which removed the API from insecure contexts. Chrome originally shipped the old behavior and didn't follow the spec change immediately because of compat concerns.

We are now removing it from insecure contexts because Chrome usage in insecure contexts turned out to be very low.

Installation notes

After downloading the package, confirm that the branch and platform match your device before launching the installer or extracting the archive. If you only need a standard everyday browser, Stable is usually the safest choice. If you are testing new behavior, Beta, Dev, and Canary are better fits.
