There were multiple objectives with this. The main one being making the game less dependant on documentation and understanding how certain items can be useful right after you find them. In addition to this, with cube rework, some recipes were made simpler (require less reagents or less steps, for example you only need 5 dogmas now). Recipes to make Secret Tokens (now Emblems) are removed and they now drop from monsters, recipes such as the ones to create Book of Ultimative are now straight forward as well. Many reagents had really inconsistent descriptions (Deity's Bow, Sunless Crystal Bird), but they are all consistent now. Some reagents were renamed and have new looks as well.
Here are some previews of the finished Cube Rework:*typo, it's Bonus, not Bonuses
In addition to this, we are about to launch our 4th alpha release to the team. So far everything is going really well, we hope to have more updates soon.
