Display override in web app manifests

The display_override field for the web app manifest allows developers to specify an explicit fallback chain for the display field. The following example specifies a "minimal-ui", falling back to "standalone":

{
  "display": "standalone",
  "display_override": ["minimal-ui"],
}

This API is intended for advanced use cases and display modes, and its capabilities are limited. You can learn more in its , as with the other ReadableStream-related classes. This eliminates a previous limitation where instances had to be created inside stream constructors.

Potentially trustworthy data: urls

To conform to current web standards, Chrome now to handle bytes efficiently, specifically by minimizing copies.
Byte streams allow for Bring Your Own Buffer (BYOB) readers to be acquired. The default implementation can give a range of different outputs such as strings or array buffers in the case of WebSockets, whereas byte streams guarantee byte output. Furthermore, being able to have BYOB readers has stability benefits. This is because if a buffer detaches, there's now a guarantee that the same buffer won't be written to twice, hence avoiding race conditions. BYOB readers also do not need to garbage collect for every read, because buffers are reused.

Support for full 'filter' property syntax on SVG elements

Chrome now . The AuthenticatorSelectionCriteria.residentKey property specifies web authentication credential registration whether a client-side discoverable credential should be created.

The Web Authentication credProps extension indicates to the relying party whether a created credential is client-side discoverable. "Client-side discoverable credentials" are a type of WebAuthn credential that can be challenged by a relying party without needing to provide the credential ID in the WebAuthn API request. Browsers display a list of all discoverable credentials from a given authenticator (either external security key or built-in) and let the user choose one to sign in with.

Today this is accomplished by wrapping modules in async functions, but this pushes complexity into dependent modules and exposes implementation details.

Remove prefixed events for <link rel=prerender>
