The project aims to provide a development environment for learning and exploring software in a hands-on way. POV-Ray has entered beta-testing for version 3.8 and recently celebrated its 30th anniversary. Additionally, new features and collaborations with other projects like Blender and white_dune are highlighted on their site.
