[sepia] Upgrading tracker.ceph.com Redmine to latest version 6.1.2.stable

On Sunday (June 14, 2026) I will upgrade Redmine on tracker.ceph.com to the latest version (6.1.2.stable). *Expected downtime*: ~30–60 minutes during the maintenance window. Please save any open work (issues, comments, etc.) before the maintenance begins. Thank you for your understanding. Feel free to reply if you have any questions. -- Adam Kraitman Systems Administrator Ceph Engineering IRC: akraitma
