Aarch64 support: we now build the Flatpak from source in order to support distros like #AsahiLinux better and a wider range of devices.
Automatic updating: an hour or so after release, the Flatpak will update to the latest version and binaries will be on official release channels in three to four hours.
Beta channels: we've set up a beta chanel that also automatically updates, so you can use the release candidates easily on #Flathub Beta!
Thanks to @grillo_delmal for figuring all of this out. It was fun.
