Base image bumped to Ubuntu 26.04 with Transmission 4.1.3.
Our previous image was running Transmission 4.0.5 which is outdated and was being blacklisted on different sites.
We're now back to building Transmission ourselves because the 4.1.1 version shipped with Ubuntu 26.04 by default also had some issues and was being blacklisted. I've created a base image to use both here and in the WireGuard version.
See #2998 for more details.
Full Changelog: v5.4.2...v5.5.0
