Webgl2

I couldn’t find any recent answers. Is Webgl2 supported in Phaser? Is there something that should be enabled in the configuration?
I’ve tried loading shaders with #version 300 es, but they failed with version unsupported message.

Also I’ve seen that on IOS you can enable Webgl2 support, anyone have any news when this might be standard?

Thank you. I’ve managed to find this example but wanted to check if there’s anything more recent.
