Hello! I have packaged Xlog into Flatpak[1] and submitted it to Flathub[2]. If you are a Xlog developer, feel free to let me know (via this mailing list thread, personal e-mail or under the Flathub Pull Request) whether you are interested in push rights to the Xlog Flatpak repository (so you can co-maintain it) after it is accepted and added to Flathub. Also feel free to let me know if you have any questions.
Thanks! :-) Regards, Daniel [1] https://flatpak.org [2] https://github.com/flathub/flathub/pull/3669
