If you are using libhandy, use the libhandy-0-0 branch instead of master — e.g. in your Flatpak manifests.
We will soon bump the API version on master to prepare libhandy 1.0, so if you get libhandy from that branch, your app *will* stop building.
It is now done, use the libhandy-0-0 branch until the new version is ready. For GNOME 3.36, we recommend using the 0.0 branch, libhandy 1 will be available for GNOME 3.38.
