The last time we introduced a new Living Standard was Infra, in 2016. This year has seen a flurry of activity, with four new standards joining the WHATWG!
The Test Utils Standard defines APIs that are not exposed on the open web by default, but are specifically useful in testing web browser functionality. So far it defines the
testUtils.gc() method, allowing us to test garbage collection-dependent APIs. James Graham is the editor.
The WebSockets Standard consolidates content that was formerly spread across the HTML Standard and the Fetch Standard. This new home will provide a natural place for standardizing the
WebSocketStream API, which integrates WebSockets with streams. Adam Rice is the editor.
Finally, the File System Standard will specify an API for an origin-private filesystem, drawn from part of the existing File System Access specification as well as the AccessHandle proposal. (The portions of the File System API specification for accessing the local file system will remain in incubation, until they gather multi-implementer interest.) Marijn Kruisselbrink will be the editor.
We're happy to see such excitement about working in the WHATWG, and will strive to continue to provide a welcoming community where new features can be developed or existing incubations can graduate. We hope you enjoy these new Living Standards. As always, feel free to join us on GitHub to discuss improvements and additions. And if there are more specifications that would like to become WHATWG Living Standards, please get in touch!
