IMPORTANT: Security Notice for all Firmware prior to 3.9.6.3:
Please see this security advisory for more information https://www.draytek.co.uk/support/security-advisories/kb-advisory-jul21

Mainline and Stable Firmware Branches:
Stable - Formal releases of firmware incorporating any bug fixes and firmware improvements.
Mainline - Incorporates new features, bug fixes and firmware improvements.

To change firmware from Stable to Mainline branch, as a precaution take a configuration backup before performing the upgrade.
To switch back to the Stable branch, use 4.3.1’s [System Maintenance] > [Configuration Export] - “Restore Firmware with Config” feature. This loads the previous configuration file along with the previous firmware.

Stable - 3.9.7.2 - Latest release
Mainline - 4.3.1 - Adds new features including SD WAN, Wireguard VPN features and USB thermometer/storage support

Firmware Filenames:
The file name extension of the firmware controls which upgrade type is performed. If the file name is unchanged (eg is xxxx.all) then the upgrade will just upgrade the firmware, whereas renaming the firmware to a .rst extension will wipe all settings back to factory defaults when upgrading the firmware.
