7.23beta2 Development 2026-Mar-13 (1 month ago)
  • added ability to set custom Option 82 with dhcp-agent-circuit-id, dhcp-agent-remote-id settings (replaces add-dhcp-option82 setting; configuration is automatically updated after upgrade);

7.22 Stable 2026-Mar-09 (1 month ago)
  • added local and static MAC synchronization for MLAG;
  • added MLAG support per bridge interface (/interface/bridge/mlag menu is moved to /interface/bridge; configuration is automatically updated after upgrade; downgrading to an older version will result in MLAG configuration loss);

  • improved logic for interface remove;
  • improved MAC synchronization for MLAG;
  • improved VRRP MAC address handling;
  • removed vlan-filtering check when changing the MVRP setting (allows disabling MVRP through WinBox);
