+_Rafx WebGL 1.0 support, [click for live demo][rafx-webgl-demo]!_
+
+Rafx is a multi-backend renderer that optionally integrates with the
+[distill][rafx-distill] asset pipeline. This month, we added frustum
+culling and a new OpenGL ES 2.0/WebGL 1.0 backend.
+
+[@dvd] revived the `rafx-visibility` crate and implemented frustum culling.
+Frustum culling greatly reduces draw call counts, improving frame rate
+in certain scenes. The changes also improve consistency between various
+rendering feature implementations (i.e. meshes, text etc.) and avoids running
+the extract-prepare-submit pipeline on entities that are not visible.
+
+[@aclysma] implemented an OpenGL ES 2.0 backend. While ES2 cannot support all
+funcionality in `rafx-api`, it provides very broad compatibility. This means
+the core functionality of rafx-api can be used with almost any mobile device
+or browser ([~98% web coverage][rafx-webgl-caniuse].)
