Exceptions to the feature-launching process

TAG review

All intents to ship are required to have a specification TAG review, unless one of the following apply:

• The intent ships a new API or augmentation of an API, or changing an API to match a spec, that is

  • already specified and accepted by the relevant standardization body, and

  • has already shipped in at least one other browser.

• The intent removes a feature or part of a feature.

• The intent is for a JavaScript/WebAssembly language feature that has reached TC39 stage 3 or WebAssembly phase 4.

• The intent is for WebDriver / WebDriver BiDi support for a feature already shipped in Chromium.

• An exception was granted by consensus of the Blink API owners through a public communication. Approval of an intent to ship by the Blink API owners with no TAG review implies such an exception.

• An Early Design Review was performed by the TAG and the final specification does not differ in any significant way from the the form reviewed by the TAG. In this situation, a comment on the Early Design Review issue (no need to re-open the issue) linking to the specification suffices.
