Hello all,

The DBSC Origin Trial’s last Chrome version is M144. However, we believe we have enough feedback to ship, and will be ending the Origin Trial early. The process of enabling DBSC for all sites will require that we disable the feature entirely for approximately 2 weeks, starting in a few weeks (we’ll follow up shortly with an exact date). This will likely terminate any existing DBSC sessions, so please ensure that this isn’t causing user experience that you deem undesirable (e.g. user logouts).

If you have any last pieces of feedback for us, please let us know! As browser developers, we have somewhat limited visibility into site developer experiences. So whether you were able or unable to implement the necessary site functionality, we’d like to hear from you. Please file issues on the GitHub repo or email dru...@chromium.org directly.

Thanks,

Dan Rubery and the Chrome DBSC team

Hello,

My original email left the exact date to be announced. We've settled on terminating the Origin Trial on Monday February 9.

Thanks,

Dan Rubery
