Google has shared the phase-out timeline for Manifest V2 Chrome extensions and its plans to bring Manifest V3 to full feature parity.
"Years in the making, Manifest V3 is more secure, performant, and privacy-preserving than its predecessor," said David Li, Product Manager for Chrome Extensions & Chrome Web Store.
Until Manifest V2 Chrome extensions are fully deprecated, Google promised to continue bringing the new manifest to full feature parity with the older version and addressing the requests made by developers.
Chrome Web Store stops accepting new Manifest V2 extensions with visibility set to "Public" or "Unlisted" Existing Manifest V2 extensions can no longer be changed from "Private" to "Public" or "Unlisted".
Chrome stops running Manifest V2 extensions Enterprise policy can let Manifest V2 extensions run on Chrome deployments within the organization.
Controversy behind the transition to Manifest V3. In the initial Manifest V3 version, Google changed webRequest's API so that extensions could only monitor browser connections but not alter any of the content before being displayed.
