Hello, We are planning upgrade review.opendev.org to the Gerrit 3.5 release on 19th June, 2022 at around 20:00UTC. This will involve an outage of around 1 hour. There should not be much user-visible change after the upgrade. There are some enhanced search predicates [1] which you may find useful. Thank you, -i [1] https://www.gerritcodereview.com/3.5.html#new-change-predicates
