Banshee is currently in active development (pre-alpha stage). We are focusing on introducing the final set of critical features, which include high quality physically based renderer, Vulkan API support and Mac/Linux ports.
We are not focusing as much on testing, polish and low level optimization, but we will have a separate beta period once a critical feature set is implemented, where we will focus purely on these aspects.
Therefore the builds currently provided are not intended for production use, but rather as development previews. We hope to have a stable version for you soon.
