Enabled by default in 54

This release of Chrome had 18 new features.

Align behavior of window.external.IsSearchProviderInstalled and window.external.AddSearchProvider with the spec

window.external.IsSearchProviderInstalled and window.external.AddSearchProvider will both be defined as methods that are no-ops. This was never implemented in Safari. In IE10, these methods are (mostly) no-ops: IsSearchProviderInstalled always returns 2, and AddSearchProvider always returns S_OK. Firefox still implements this, but notes that it may be removed at any time. #

This feature was specified in this Spec.

CECPQ1 in TLS

CECPQ1 is a post-quantum cipher suite: one that is designed to provide confidentiality even against an attacker who possesses a large quantum computer. It is a key-agreement algorithm plugged into TLS that combines X25519 and NewHope, a ring-learning-with-errors primitive. Even if NewHope turns out to be breakable, the X25519 key-agreement will ensure that it provides at least the security of our existing connections. This is only an experiment and will only be used on a small fraction of HTT #

Enterprise flag to allow continued use of SHA-1 certificates by private PKIs

Private PKIs are not bound by the CA/Browser Forum's Baseline Requirements, and many not have completed the process to deprecate SHA-1 by Jan 2017, after which we'll start showing interstitials. Provide an enterprise flag that would cause SHA-1 certificates that chain to a locally installed trust anchor to display the standard HTTP page icon after Jan 2017. #

PushSubscription.options

An "options" attribute is added to PushSubscription objects that the PushManager.subscribe(...) and getSubscription() promises resolve to. It reflects the options passed in when subscribing. This allows web developers to see what applicationServerKey each PushSubscription is associated with, and hence what key their server will need to present when sending messages. Previously web developers with more than one applicationServerKey had to keep track of this separately (e.g. in IndexedDB). #

Flagged features in 54

This release of Chrome had 1 are available behind a flag.

SRI: The `require-sri-for` CSP directive.

The `require-sri-for` directive gives developers the ability to assert to the browser that every resource of a given type ought to be integrity checked. If a resource of that type is loaded without integrity metadata, it will be rejected without triggering a network request. #

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:

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:

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.

Deprecated features in 54

This release of Chrome had 2 features deprecated.

Beacon with non-CORS-safelisted Content-Type

sendBeacon() has been available as described in https://www.chromestatus.com/feature/5517433905348608. A part of sendBeacon()'s functionalities has been temporarily disabled later due to a security issue. The change is that, from M60, sendBeacon() will throw when called with a Blob whose type is not a CORS-safelisted value for the Content-Type request header as the data argument. This entry is used for tracking progress on resolving the issue and re-enabling the functionality. #

Deprecate SVGSVGElement.viewport attribute

The implementation is trivial but entirely useless and has been since 2012. The attribute is not present at all in Gecko. It has been removed from the spec: https://github.com/w3c/svgwg/commit/99a342c09dc0f8f164667d45d1c8486f0f87af8f #

Removed features in 54

This release of Chrome had 5 features removed.

Blocking sync XHR during microtask execution

Certain blocking APIs spin up nested message loops. Invoking those APIs during microtask execution has undesirable effects, e.g., it is possible that events are dispatched during microtasks. Those APIs currently are alert, prompt, confirm, print, and send() on synchronous XHRs. #

Deprecate and Remove SVGZoomEvent

SVGZoomEvent has been removed from the SVG 2.0 specification and has a non-functional implementation in Chromium. Since it doesn't work but is still feature detectable, it's in a confusing state right now and should be removed. #

This feature was specified in this Spec.

Deprecate and remove initTouchEvent

Chrome’s initTouchEvent is not interoperable with Safari's or Firefox’s version of initTouchEvent. Deprecated since M49. Developers should use the new TouchEvent constructor. See https://www.chromestatus.com/features/4923255479599104 #
