Using the KDE Craft build system, we have an experimental Tellico 3.4.4 installer for Microsoft Windows. Most of the basic functionality seems to work, though I’m sure there are aspects that don’t quite behave as expected. A few bugs have been filed.
I have little resources or expertise in debugging Windows-specific bugs, but I’m certainly open to feedback, bugs, or anything else related to the build. There are also nightly builds against the master branch in the KDE CI system.
