I remember there were similar problems when you released 0.16, and posila managed to fix it eventually. I know there was talk at some point later about dropping support for Mavericks with the rendering engine update, and I suspect this is what's happened, but the download page still says 'compatible with Mavericks', so I'm not sure.
I mentally prepared for this eventuality, and I started shopping for a new computer already, just looking for confirmation.
