Audit trail went live under the task queue; Central Firewall Reporting enhancements. But also for all others v18 MR3 comes with 34 bug fixes and some new features. Currently, there are still two different versions of SFOS being updated by Sophos. There is v17.5 (MR6 — MR14.1) and version 18 (MR1 and MR2). Users of an XG 85 or XG 105 cannot upgrade to v18 because of insufficient RAM. You have two standalone firewalls running 18.0 MR3 managed from Sophos Central. You want to import the configuration from one of them and manage them as a HA pair. Upgrade both firewalls to 18.0 MR4. For more information, see Move to a different firmware version.
