Hopefully this release will be accepted by Flathub so Flatpak users will finally be able to run Therion from Mapiah.

The other packages - Liux/AppImage, MacOS and Windows could do it since version 0.2.37 but neither 0.2.37 nor 0.2.38 were accepted by Flathub for "security issues", i.e., Mapiah was trying to call an external app, Therion. To solve this issue I had to bundle Therion inside Mapiah Flatpak package. It seems as an abomination to me but I am trying to see if it works well enough for me to keep doing it. As far as my tests show, it is working but Therion is way slower inside Mapiah Flatpak package. This might be solvable. Lets see what the future brings us.
