The https://collector.openwebdocs.org/ project (v10.20.7) found new features shipping in Chromium 153 beta which was released yesterday. Currently, the collector covers about 90% of BCD, so the following list might not be exhaustive. Also, if a feature is in Canary/behind flags, it is not considered here.

Chrome 153 releases on September, 8, 2026. This PR needs to be merged before the BCD release on September 3, 2026.

With this PR, BCD will consider the following features as shipping in Chromium 153 (bold features are new keys in BCD).

  • api.BaseAudioContext.renderQuantumSize (ref)
  • api.Document.browsingTopics (removal) (ref)
  • api.HTMLElement.autocorrect (152->153) (ref)
  • api.HTMLIFrameElement.browsingTopics (removal) (ref)
  • css.properties.scroll-axis-lock (ref)
  • css.properties.scroll-axis-lock.auto (ref)
  • css.properties.scroll-axis-lock.none (ref)
  • javascript.builtins.Iterator.join (ref)
  • javascript.builtins.Iterator.zip (ref)
  • javascript.builtins.Iterator.zipKeyed (ref)

Note: There are also new capability elements: <camera> and <microphone>, however, they are not in a spec which is considered by browser-specs, see w3c/browser-specs#1915. I will follow-up on these separately.
