Definition of a web-exposed change to Chromium

Web-exposed is defined as affecting web API behavior to the point that developers using that API need to be aware of it.

Changes that are web-exposed:

• Any change that adds a new API, or in general modifies any IDL file to change what APIs developers see.
• Removal of some or all of an API.

Cases that are usually not web-exposed:

• Fixing a bug in the implementation to conform better with a defined specification.

Cases that might or might not be web-exposed:

• Fixing a broken implementation in a way that may break significant numbers of sites.
