Rolling back

If rolling back earlier than 6.12.0, also see the 6.12.0 release notes.


This is mainly a bug fix release, including also a minor security update. Other highlights:

  • We reverted docker from v23.0.6, introduced during Unraid OS 6.12 development, to v20.10.24, which is the latest patch release of docker used in Unraid OS 6.11. This to address increased memory usage and other issues discovered with docker.
  • A small necessary change to invoke our 'update_services' script whenever a WireGuard tunnel starts or stops is automatically applied to all 'config/wireguard/*.conf' files when you update via Update OS page. For manual update or if you downgrade, it is necessary to make a "dummy change" in a setting on the Settings/VPN Manager page and then click Apply.
