+
+Rafx is a multi-backend renderer that optionally integrates with the
+[distill][rafx-distill] asset pipeline.
+
+This month, [@dvd] completed work on the new job system. It implements three
+steps: extract, prepare, and write. These jobs are now more structured, making
+them easier to implement while supporting concurrent execution and reducing
+dynamic allocation. They also integrate with a visibility system to ensure that
+off-screen objects are not processed.
+
+[@aclysma] continued work on OpenGL ES 2.0/3.0 backends and documented
+[implementation details][rafx-implementation-details] of currently available
+rendering backends.
+
+Additionally, some rendering features were improved and added: mesh rendering
+now uses an instance-rate vertex buffer instead of per-object uniforms,
+improving performance. Rendering features now support wireframe and untextured
+rendering modes. An egui render feature was added, and the demo now uses egui
+instead of imgui.
