Chrome 71 also includes changes to cache.addAll() and importScripts(). Read
about it in Tweaks to cache.addAll() and importScripts() coming in Chrome 71 by Jeff Posnick.
Remove SpeechSynthesis.speak() without user activation
The SpeechSynthesis
interface is actively being abused on the web. There's anecdotal evidences that
because other autoplay avenues are being closed, abuse is moving to the Web Speech API,
which doesn't follow autoplay rules.
The speechSynthesis.speak() function now throws an error if the document has
not received a user activation. This feature has been deprecated since Chrome 70.

Remove prefixed versions of APIs
Chrome has removed non-standard aliases for two widely supported standard interfaces.
WebKitAnimationEvent
WebKitAnimationEvent has been fully replaced by
AnimationEvent
, the event interface used for events relating to CSS Animations. The prefixed
form is only supported in Safari. Firefox and Edge only support the un-prefixed
AnimationEvent.

WebKitTransitionEvent
WebKitTransitionEvent has been fully replaced by
TransitionEvent
, the event interface used for events relating to CSS Transitions (for example,
transitionstart). The prefixed form is only supported in Safari. Firefox and
Edge only support the un-prefixed TransitionEvent.

Remove URL.createObjectURL from MediaStream
The URL.createObjectURL() method has been removed from the MediaStream
interface. This method has been deprecated in 2013 and superseded by assigning
streams to
HTMLMediaElement.srcObject.
The old method was removed because it is less safe, requiring a call to
URL.revokeOjbectURL() to end the stream. Other user agents have either
deprecated (Firefox) or removed (Safari) this feature feature.

Remove document.origin
The document.origin property has been removed. This property was only ever
implemented in Chromium and WebKit. It is redundant with self.origin which
can be used in both window and worker contexts
and has wider support.

Deprecations
No features have been deprecated in this version of Chrome. Chrome Platform Status provides a list of deprecated features from previous versions of Chrome.
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- They are superseded by newer APIs.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.
