Since 2014? A lot of things have happened. We now have galaxies, chambers to enhance various functions of your ship, better textures, FTL, more weapons (currently a lot of that is broken, as some weapon systems will be replaced next update and they're not updating it as a result), a new power system and new shields, thrust direction editing, a new player model (wait, did Dave exist in 2014? I don't think so...) some weapon/tool models, 3D-modeled blocks like pipes and consoles, glowing crystal blocks and wedges in all colours of the rainbow (also ice crystal wedges! :D), a logic system (did that exist in 2014? I don't think so, but if it did there have been some additions since then, including a sensor system and randomizers), and lots of other things I won't list because the result would be an immense wall of text. :P
