The biggest change in Iridescent Industry 0.8 is a significant revision of prismorphing. The old mechanics were a bit weak: use colored liquids as an alternate recipe to make common stuff. It wasn't the worst thing ever, but the eldritch furnace is available sooner and is simpler to set up. Also, most people playing with Iridescent Industry also have Voidcraft installed, and these mechanics can kind of feel like off-brand voidcrafting. So ultimately I don't think it ever really felt all that satisfying, and I have to admit I didn't make a lot of use of it in my own factories.
To give prismorphing more of a unique identity, I've tried to reinforce a distinct theme for each color. Crimson essence allows you to make crimsonite, which is perhaps the least changed, since its main use is being forged into plates, steel, and other useful components. You can also use stone as filler to get more crimsonite out of your crimson essence. Verdant essence is crafted into verdance, a fuel that gives off 10% of the normal amount of pollution, which will help keep the biters away and the Arcanyx spirits calm. Azure essence lets you make azurystals, which are crystals that function like powerful speed modules, giving a +50% bonus to speed, but only for 2 minutes. Fortunately, you also get the azurystal nexus, which automatically replaces nearby azurystals as they expire.
I've also added the prismixer, a new building for making use of these new recipes, as well as other prismite recipes, with a speed of 1.25, so it has a slight boost over a chemical plant, albeit for a more specific set of recipes. On Arcanyx (or if you're otherwise using Voidcraft) the prismixer takes runes and can also handle recipes involving void flux and coherence.
This is a breaking change, but I've tried to make things easier on you if your infrastructure relies upon the old prismorphing mechanics. A setting will allow you to either use the old or new mechanics entirely, or enable a transitional mode allow both sets of mechanics to exist more or less side-by-side; this is of course pretty messy and it is recommended to only have it enabled to change your base over without everything shutting down.
