Deprecations and removals in Chrome 62

In nearly every version of Chrome, we see a significant number of updates and improvements to the product, its performance, and also capabilities of the Web Platform. This article describes the deprecations and removals in Chrome 62, which is in beta as of September 14. This list is subject to change at any time.

# Remove RTCPeerConnection.getStreamById()

Nearly two years ago, getStreamById() was removed from the WebRTC spec. Most other browsers have already removed this from their implementations, and the feature was deprecated in Chrome 60. Though this function is believed to be little-used, it's also believed there is some minor interoperability risk with Edge and WebKit-based browsers other than Safari where getStreamById() is still supported. Developers needing an alternative implementation can find example code in the Intent to Remove, below.

# Remove SharedWorker.workerStart

This property, which was intended for use in monitoring worker performance was removed from the spec more than two years ago and it is not supported in the other major browsers. A more modern approach to tracking performance of a worker would use Performance.timing.

# Remove SVGPathElement.getPathSegAtLength()

In Chrome 48, SVGPathElement.pathSegList() and related interfaces were removed in compliance with the SVG specification. At that time, this method was mistakenly left in. We don't expect this removal to break any web pages since, for the last two years, it has returned an object that no longer exists in Blink.

# Remove usage of notifications from insecure iframes

Permission requests from iframes can confuse users since it is difficult to distinguish between the containing page's origin and the origin of the iframe that is making the request. When the requests scope is unclear, it is difficult for users to judge whether to grant or deny permission.

Disallowing notifications in iframes will also align the requirements for notification permission with that of push notifications, easing friction for developers.

Developers who need this functionality can open a new window to request notification permission.
