Greetings extension devs,

As we head towards Manifest V3 migration, we are intently monitoring comments from the developer community to help inform our timelines. We’ve heard your feedback on common challenges posed by the migration, specifically the service worker’s inability to use DOM capabilities and the current hard limit on extension service worker lifetimes. We’re mitigating the former with the Offscreen Documents API (added in Chrome 109) and are actively pursuing a solution to the latter.

We’re committed to providing developers solutions to migration challenges with new functionality, bug fixes, and adequate time for adoption. For this reason, we’re postponing any January experiments to turn off Manifest V2 in pre-release channels of Chrome and changes to the featured badge in the Chrome Webstore, and we'll be evaluating all downstream milestones as well. Expect to hear more about the updated phase-out plan and schedule by March of 2023. Our guiding principle will be to give developers sufficient time to update and test their extensions after the launch of these new capabilities before turning off Manifest V2.

Thank you for all the feedback and passionate discussion thus far, and we wish you a happy start to 2023.
