Hello all,

The DBSC Origin Trial’s last Chrome version is M139, so the trial will end as users update to M140, starting September 2, with a hard cutoff of October 13. This will terminate any existing DBSC sessions, so please ensure that this isn’t causing user experience that you deem undesirable (e.g. user logouts). Based on feedback so far, we’ve made some spec changes that will require a second Origin Trial before shipping. Our new timeline is a second Origin Trial in M142 - M144.

We’re also eager for any feedback about the operation of DBSC server-side endpoints. 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. Here is our feedback form.

Thanks,

Dan Rubery and the Chrome DBSC team
