Unfortunately, Badger will no longer receive updates on Flathub, but you can still download a Flatpak from https://appcenter.elementary.io/com.github.elfenware.badger. It will receive regular updates. Technical details: This decision was made because we depend on the elementary SDK, which is not fully compatible with the elementary BaseApp available on Flathub, and may diverge further, causing maintenance issues. Thanks for using Badger, and apologies for the inconvenience.
