Chrome 106 beta was released on September 1, 2022 and is expected to become the stable version in late September, 2022.
Remove non-ASCII characters in cookie domain attributes
To align with the latest spec (RFC 6265bis), Chromium now rejects cookies with a Domain attribute that contains non-ASCII characters (for example, éxample.com).
Support for IDN domain attributes in cookies has been long unspecified, with Chromium, Safari, and Firefox all behaving differently. This change standardizes Firefox's behavior of rejecting cookies with non-ASCII domain attributes.
Since Chromium has previously accepted non-ASCII characters and tried to convert them to normalized punycode for storage, we will now apply stricter rules and require valid ASCII (punycode if applicable) domain attributes.
Remove HTTP/2 push
Chrome has removed the ability to receive, keep in memory, and use HTTP/2 push streams sent by the server. See Removing HTTP/2 Server Push from Chrome for details and suggested alternative APIs.
Remove Persistent Quota
The window.PERSISTENT quota type in webkitRequestFileSystem() is now deprecated.
Support for the PERSISTENT quota type contributes some amount of complexity to the quota system, but webkitRequestFileSystem() is the only consumer, and it's a form of storage that never caught on and is very seldom used.
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- They are superseded by newer APIs.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.
