Sophos (XG) Firewall v18 Maintenance Release 6 is packed with bug fixes, troubleshooting enhancements and security fixes.
While we always encourage you to keep your firewalls up to date with the latest firmware, over the next few months we are recommending you rapidly apply maintenance releases to ensure you have all the important security, performance, and feature enhancements applied as soon as possible.
Also ensure you have automatic pattern updates enabled so that you can be assured you have the latest protection updates.
Sophos (XG) Firewall v18 MR6 is an easy and fully supported upgrade from XG Firewall v17.5 MR6+ (including the latest v17.5 MR16 release). Please refer to the Upgrade information tab in the release notes for more details.
As usual, this firmware update is no charge for all licensed XG Firewall customers. The firmware will be rolled out automatically to all systems over the coming weeks, but you can access the firmware anytime to do a manual update through the Licensing Portal. Please refer to the documentation for more information on how to apply firmware updates.
And if you still haven’t upgraded to v18, or are still exploring many of the new features, be sure to take advantage of all the resources available, including the recent “Making the Most of XG Firewall v18” article series that covers all the great new capabilities in XG Firewall v18:

I've recently upgraded to 18.5 MR1, am i safer on that version and build?
You should not be able to install a MR4 on a MR6 installation?
Just downgraded an Appliance to 18.0.4 and it went factory default
Migrating config from SFOS 18.0.6 MR-6-Build655 to SFOS 18.0.4 MR-4ERROR: config migration failed. Reason: Firmware SFOS 18.0.4 MR-4 (18.031) does not support config migration from SFOS 18.0.6 MR-6-Build655 (18.035). Default config will be installed.
did I miss something in the release notes?
Build numbers basically reset which each major update. So you start with V18.0 Build 1 and V18.5 Build 1. Each update will update Independent.
