Earlier this evening, I sent in PRs on ATOM and many of it's constituent mods, covering issues that have been reported here and on discord over the last few months along with some I've found myself. Some of them are entirely cosmetic - fixing localizations, animations, and icons - but if everything is implemented as-is there will be recipe changes that will require base changes, mostly but not exclusively post-space science.
It occurred to me that people might like some warning before they update. Thus, the list below. It doesn't cover every change, but I believe I caught everything that is likely to be mass produced. I'm willing to answer questions about any given change, but I'll let you know up front, most of them are "something had a typo and I fixed it".
General: Many K2 matter recipes have been adjusted for consistency - some things that used non-basic stabilizers now use basic ones, some that used no stabilizer require one (mostly basic).
Particle stream amounts in both matter fusion and matter liberation have increased significantly, again for consistency.
bzaluminum2: Several low density structure recipes no longer require copper plates.
bismuth: Efficiency modules require some solder.
Bismuth glass recipe that looks like it should require pyroflux now does.
bzcarbon2: Both nutrient gel recipes require fullerenes.
Low density structures require more carbon fiber.
Empty singularity fuel cells require graphene.
bzchlorine2: Both nutrient gel recipes require salt.
Iridium-catalyzed water electrolysis uses salt instead of sand and has had it's time adjusted.
Bioelectrics data requires salt.
bztin2: Several glass recipes no longer have their tin byproduct affected by productivity. Productivity modules will still improve glass production, but it won't turn into a tin producer with enough modules.
bztungsten2: Energy control units require copper tungsten.
Armor piercing rifle magazines, armor piercing anti-materiel rifle magazines amd railgun shells require tungsten plates (and may no longer require steel plates).
Heavy rockets and explosive turret rockets require rocket engine nozzles.
bzzirconium2: AI cores require cermet.
Matter stabilizers require zirconium plates instead of imersite.
ChemistryForYou2: Iridium-catalyzed water elctrolysis produces sodium hydroxide.
Lithium battery recipe and battery recipe that uses lithium use lithium hydroxide instead of plain lithium.
Chromium2: Nitinol plates use chromel-r fabric instead of nickel plates.
LasingAround-Updated: Air Scrubbing Oil Processing uses filtered oil instead of crude oil.
Laser mill has additional pipe connections... but the game won't load if you install this before the ATOM update.
Limestone2: Bismuth glass with pyroflux recipe from bismuth now uses quicklime instead of calcium plates.
Tantalite2: Space rails no longer require titanium plates. Those were supposed to be replaced by tantalum-titanium beams rather than just having the beams added on.
ThemTharHills-Updated: Advanced flow controllers require advanced circuits instead of integrated circuits.
