A GitLab upgrade is scheduled for Monday, April 7, 2025. Service interruptions are expected in the morning. We'll keep you posted on the progress of the upgrade on the Mattermost channel: https://mattermost.inria.fr/devel/channels/gitlab. We recommend that you do not work on the platform until an announcement indicates that maintenance is complete.
