This is from the 0.4 branch of development. Our experimental releases
are derived from here.

Changes in AppImage Land: Our AppImage files now are signed and support
bandwidth-saving updates via AppImageUpdate. They no longer carry their
version in the filename because after an update, that would be a lie.

We now support installation via Flatpak for the 64-bit Linux client. Get
the stable versions from Flathub; our own repository has those and also
carries the usual test builds.

We started to integrate builds for macOS. Consider them alpha for now,
testing and patches very welcome. The current macOS specific issues can
be viewed on our tracker.

0.2.9.1.1 worked around a crash bug in the (otherwise splendid)
sdl12-compat library.
