Add support for Promise to Blobs in clipboard item

Add promise support to `ClipboardItem` object. This helps the web author to call async clipboard write method without having to provide the Blob data synchronously. Authors can choose to resolve the promise later when the Blob data is available. #

This feature was specified in this Spec.

COLRv1 Color Gradient Vector Fonts

To solve problems with existing color font formats, we designed a next generation font format suitable for the web called COLRv1 which enables powerful 2D graphics glyph definitions (gradients, transforms), supports variations, and reuses existing contour definitions. Previous color font formats embed bitmap files into the OpenType font containers. They do not scale in high quality and have a large binary size. OpenType SVG embeds vectors but requires complex parsers and rasterisers. #

CSS Color Adjust: 'only' keyword for color-scheme

The 'only' keyword has been re-added to the specification for color-scheme as a way of per-element opt-out of color-scheme override like forced darkening. div { color-scheme: light } will force the div element into color-scheme dark and apply forced darkening. div { color-scheme: only light } will keep the color-scheme for the element light and opt-out of forced darkening. #

This feature was specified in this Spec.

HDR CSS Media Queries: dynamic-range

Adds a media query to CSS which allows a page to detect the current display device’s support for HDR. This feature adds the query: 'dynamic-range' which may be one of 'standard' or 'high'. Chrome will resolve this query according to the capabilities of the display device the browser window is currently positioned on, allowing pages to toggle CSS rules accordingly or respond in Javascript via 'window.matchMedia()'. #

New window.open() popup vs. window behavior

This change aligns Chromium with the spec for window.open(), by 1) adding a "popup" windowFeature to control popup vs. tab/window, and 2) ensuring all BarProp properties return !is_popup. #

This feature was specified in this Spec.

WritableStream controller AbortSignal

The streams APIs provide ubiquitous, interoperable primitives for creating, composing, and consuming streams of data. This change permits an underlying sink to rapidly abort an ongoing write or close when requested by the writer. #

This feature was specified in this Spec.

self.structuredClone()

Enables using the HTML structured clone algorithm synchronously for cloning and transferring objects within a single realm. #

This feature was specified in this Spec.

Deprecations and Removals

Deprecation policy

To keep the platform healthy, we sometimes remove APIs from the Web Platform which have run their course. There can be many reasons why we would remove an API, such as:

• They are superseded by newer APIs.
• They are updated to reflect changes to specifications to bring alignment and consistency with other browsers.
• They are early experiments that never came to fruition in other browsers and thus can increase the burden of support for web developers.

Some of these changes will have an effect on a very small number of sites. To mitigate issues ahead of time, we try to give developers advanced notice so they can make the required changes to keep their sites running.

Chrome currently has a process for deprecations and removals of API's, essentially:

• Announce on the blink-dev mailing list.
• Set warnings and give time scales in the Chrome DevTools Console when usage is detected on the page.
• Wait, monitor, and then remove the feature as usage drops.

You can find a list of all deprecated features on chromestatus.com using the deprecated filter and removed features by applying the removed filter. We will also try to summarize some of the changes, reasoning, and migration paths in these posts.

Remove SDES key exchange for WebRTC

The SDES key exchange mechanism for WebRTC has been declared a MUST NOT in the relevant IETF standards since 2013. The SDES specification has been declared Historic by the IETF. Its usage in Chrome has declined significantly over the recent year. This intent is to deprecate and remove this code from Chromium and WebRTC. #
