I've read some news about Godot 3, and most of it seems to be about the 3D engine, the visual scripting, support for more languages, GDNative, etc. Is there anything new regarding the 2D engine, specifically?
Here's a few new features for the 2D engine (from Juan's twitter):
-- Soft shadows and better light colorspace handling: tweet
-- Better 2D physics (Kinematic character): tweet
-- Easier to use 2D HDR: tweet
-- GPU Particle emission masks: tweet
-- Support for 100k particles: tweet
-- Normal maps for Sprite and most Node2D nodes: tweet
-- Filtered texture maps for tiles without bleeding edges: tweet
-- Area2D can redirect a positional 2D sound to a specific audio mixer: tweet
-- Helpers to make 2D split screen easier: tweet
There's probably more, but those were all the ones I could find in a relatively quick amount of time. There are several quality of life improvements to the editor that will help with using the 2D engine (as well as the 3D). There is also the new Audio engine, the redesigned input, and other little changes (like the JSON api) that will make working on games easier no matter what dimension you're working on.
Wow, that's quite mouth-watering stuff.
