there will be much faster parsing and lower memory consumption. We will improve our internal testing, and fix some long standing bugs.
The short time frame means no PBR material for v5, that one is being postponed to v6 (hopefully)
We can live whithout new PBR coz you know... 2.5D DISPLACEMENT IS COMING !!!!! That will be a game changer for us! That plus the overall optimizations, can't wait for that!
And I can't stop smiling by looking at the potential feature pool on trello. All of my own most-wanted features are there. Keep-it up guys, you rock !
