Notifications using Service Workers

Web Notifications have an in-page event delivery model by default, which means that notifications cannot reliably outlive the page's lifetime. Allowing event delivery to be routed to a page's Service Worker provides a solid solution. #

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 42

This release of Chrome had 1 features deprecated.

WebAudio: Deprecate setting AudioBufferSourceNode.buffer more than once

Setting AudioBufferSourceNode.buffer more than once is deprecated. A deprecation message is displayed if the buffer attribute is assigned more than once. #

This feature was specified in this Spec.

Removed features in 42

This release of Chrome had 1 features removed.

showModalDialog

The global showModalDialog() method displays a modal dialog box containing a specified HTML document. This feature has an incredibly high cost in terms of code complexity since it requires us to run an event loop on top of an arbitrary JavaScript stack. It also complicates the web platform by making task dispatch reentrant and hard to reason about. In Chrome 37 it was disabled and in Chrome 43 it is removed. #

This feature was specified in this Spec.
