XUASTC was just released, allowing for all ASTC Block sizes to be used on the web, once support lands in the big web 3D libraries like Three.js [1].

To me, this is huge. Relying on pre-calculated lighting when building stuff like [2], I constantly fight for VRAM, as older iPhones have very strict limits. XUASTC brings the all the remaining modern GPU compression schemes to the web in a standardized manner.
