CSP2: Exclude 'blob:' and 'filesystem:' from the 'self' source expression.

Document's "first-party" takes ancestors into account.

I'd like to make a small change to the definition of "first-party" that we use for third-party cookie blocking: we currently look only at the top-level origin to determine the first-party origin for a request. I'd like to start walking the whole ancestor chain of a frame. #

Service Worker: Client.postMessage() and ServiceWorkerMessageEvent

Before Chrome 45, a Service Worker sending a message via Client.postMessage() results in a MessageEvent fired on the Client's global scope (e.g., window). Since Chrome 45, the event is a ServiceWorkerMessageEvent fired on navigator.serviceWorker rather than window. Until Chrome 45, Client.postMessage displayed an "experimental, may change" deprecation warning. #

Stop sending mouse position updates during scrolling

While scrolling via trackpad or mousewheel, we previously sent mouse position updates every 100ms. On pages with heavy mouse handlers or :hover styles, this could cause significant amounts of scroll jank. Sending a mouse position update includes updating :hover styles, and dispatching mousemove, mouseover, mouseenter, mouseleave, and mouseout events. We’re planning to stop sending mouse position updates while scrolling. Instead, we'll trigger this behavior 100ms after scrolling ends. #

Subresource Integrity

Subresource Integrity defines a mechanism by which user agents may verify that a fetched resource has been delivered without unexpected manipulation. In a nutshell, metadata inlined into HTML elements allows the browser to determine whether the resource that was downloaded matches the resource the page's author expected to download. This implementation covers only the two elements outlined in the spec: <script> and <link rel="stylesheet"> elements. #

This feature was specified in this Spec.

Touch event timeout on mobile sites

Chrome on Android currently has a touch ACK timeout of 200ms for desktop sites. If the renderer does not respond to a touch event before the timeout delay, the touch sequence is cancelled and any associated gestures are dispatched. This change restores a touch timeout for sites with a mobile-friendly viewport, but with a timeout delay of 1 second. #

rtcpMuxPolicy

The rtcpMuxPolicy is used by the application to specify its preferred policy regarding use of RTP/RTCP multiplexing. When the policy is "negotiate", the ICE candidates for both RTP and RTCP will be gathered. If the remote-endpoint is capable of multiplexing RTCP, multiplex RTCP on the RTP candidates. If it is not, use both the RTP and RTCP candidates separately. Note: The removal of this feature is not certain. Please comment on the launch bug #685727 if there is any concern. #

This feature was specified in this Spec.

Audio and video tracks

This adds the ability to get information about multiple audio and video tracks, and switch between them using the AudioTrack.enabled and VideoTrack.selected attributes. #

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.

NPAPI plug-in support

NPAPI’s 90s-era architecture has become a leading cause of hangs, crashes, security incidents, and code complexity in Chrome. Because of this, Chrome will be phasing out NPAPI support in 2013. #

This feature was specified in this Spec.

Push API: PushSubscription.subscriptionId

[Deprecated in Chrome 44, removed in Chrome 45] The Push API previously exposed two properties identifying the subscription: {endpoint, subscriptionId}. These will be merged to be only a single property: endpoint. Developers can update their implementation by only considering endpoint if it considers the contents of subscriptionId. #
