Before you update (1 of 2) ​

Index · Next: Before you update (2 of 2)

134 change(s) in this release need something from a world that already exists, worst first. Nothing else in the document has to be read before you update. This does.

Back up your world first.

Items disappear (14) ​

Something you are holding or have placed is deleted by the update. Deal with it before you update. Where an item is unregistered rather than remapped, Forge reports missing item mappings on the first world load, and a dedicated server needs -Dfml.queryResult=confirm or an interactive console to get past that prompt.

  • AE2FluidCraft-Rework #340 Major refactor replacing custom fluid GUIs with Applied Energistics 2 universal GUIs.
    • What to do: The Fluid Terminal, Fluid Pattern Terminal, Fluid Pattern Terminal Ex, Fluid Level Emitter, Fluid Storage Monitor, Fluid Conversion Monitor, Wireless Fluid Terminal and Fluid Discretizer no longer exist; placed parts and stored stacks will disappear. Break them and craft them away before updating, or accept the loss; the AE2 universal terminal takes over all of their jobs. Fluid cells, fluid interfaces and storage buses are untouched.
    • Told in Applied Energistics and its addons
  • GT5-Unofficial #6807 Removed White Metal from the game entirely.
    • What to do: White Metal is deleted. Any ingots, dusts, plates, springs, fine wire or foil you hold disappear on first load, and nothing converts them.
    • Told in Removals
  • GT5-Unofficial #6691 Removed PTMEG (Polypropylene Terephthalate Methyl Glycol) and associated chemicals that were only used to craft it.
    • What to do: PTMEG Elastomer, Polytetrahydrofuran, Tetrahydrofuran, Acidicised 1,4-Butanediol, Tungstophosphoric Acid, Toluene Diisocyanate and Toluene Tetramethyl Diisocyanate are all removed, with no recipe to convert them. Their dusts, ingots, plates, cells and placed blocks disappear on first load, turning into dirt or nameless stacks, and any of their fluids left in tanks or pipes is lost. ZPM and higher recipes no longer use PTMEG.
    • Told in Removals
  • GT5-Unofficial #6351 Reworks High-Temperature Gas-Cooled Reactor with new fuel system using meta items instead of NBT, and removes the multiblock floor requirement.
    • What to do: Every TRISO and BISO fuel pebble is a separate item now. Pebbles made before this update are not converted and disappear on first load; craft them again.
    • Told in Changes & Reworks
  • GT5-Unofficial #6301 GregTech's own material capsules have been removed: the per-material capsule and molten capsule items are no longer registered, and their GT recipes and NEI entries are gone.
    • What to do: The four GT capsule and molten-capsule item types are unregistered with no replacement, so a GT-fluid-filled wax or refractory capsule you were holding disappears on first load. Almost nobody has these; they were hidden from NEI in 2.8.4. Forestry's own capsules keep working, you just cannot fill them with GT fluids.
    • Told in Removals
  • GT5-Unofficial #5821 Removed the Pest Killer machine and all associated code.
    • What to do: The Pest Killer no longer exists: placed machines disappear from an existing world.
  • GT5-Unofficial #5651 Formally removed deprecated laser source and target hatches rather than just hiding them.
    • What to do: The deprecated laser source and target hatches are removed from the game; any you have placed disappear on world load and any multiblock that used one will unform. Swap them for the current laser hatches before you update.
    • Told in Changes & Reworks
  • GT5-Unofficial #5650 Completed the removal of single-amp wireless dynamos that were deprecated since version 2.8.
    • What to do: Single-amp Wireless Dynamos have been removed from the game; any placed instances will disappear on world load.
  • GT5-Unofficial #5648 Completed the removal of the deprecated Slicing Machine that was marked for removal since version 2.8.
    • What to do: Slicing Machines have been removed from the game; any placed instances will disappear on world load.
    • Told in Removals
  • GT5-Unofficial #5646 Completed the removal of deprecated Tool Casting Machines that were marked for removal since version 2.8.
    • What to do: Tool Casting Machines have been removed from the game; any placed instances will disappear on world load.
    • Told in Removals
  • GT5-Unofficial #5251 Removed deprecation from Assembler cable recipes and deleted the single-block cable coater machine.
    • What to do: The Basic Cable Coater and Advanced Cable Coater I, II and III are unregistered with no replacement, so any you have placed or are holding disappear on first load.
    • Told in New Content
  • NewHorizonsCoreMod #1684 Removed most NHCoreMod fluid declarations and their block/bucket counterparts, reducing dependency on YamCore.
    • What to do: The bucket items and the placeable liquid blocks for Sodium Potassium, Nitric Acid, Ammonia, Pollution and the Bacterial Sludges are removed - any you are holding or have placed disappear silently. The fluids themselves are unchanged, since GregTech now registers them under the same names, so tanks, pipes and recipes keep working. Compressed Oxygen and Compressed Nitrogen are gone outright.
    • Told in Changes & Reworks
  • NewHorizonsCoreMod #1667 Metal bars are now placeable as decorative blocks.
    • What to do: Conductive Iron, Electrical Steel, Enderium, Enderium Base, Energetic Alloy, Pulsating Iron, Redstone Alloy, Soularium, Tungsten and Vibrant Alloy Bars are deleted and their stacks disappear silently on first load. All ten were decorative and no recipe used them, so nothing else breaks; for Soularium, EnderIO's own bars take over the ore dictionary entry. The nine other bars (Aluminium, Chrome, Iridium, Neutronium, Osmium, Stainless Steel, Steel, Titanium, Tungstensteel) become placeable blocks and convert on load.
    • Told in Recipes, quests and progression
  • ThaumicEnergistics #98 Essentia is now handled natively by AE2 instead of using fluid/item hacks, fixing control-click crafting, tank storage, and terminal behavior.
    • What to do: The Wireless Essentia Terminal and the Essentia Cell Workbench no longer exist, so placed workbenches and stacks of either disappear on load. Every "Gaseous <Aspect>" fluid is gone: empty tanks, fluid cells and fluid interfaces into an Essentia Cell first, since essentia already in a cell carries over. Essentia patterns need re-encoding by hand. The Essentia Terminal, Level Emitter and Storage/Conversion Monitors still work but are deprecated.

World data (8) ​

Saved data changes shape.

  • CropsNH #4 Complete rewrite of the crop system from scratch with all crops re-added, deterministic breeding, and Agricraft-style spreading.
    • What to do: Your IC2 crops, crop sticks and seeds are converted to CropsNH as your save loads, keeping their growth, gain and resistance stats along with their nutrient, water and weed-EX buffers, so do not break them beforehand. The GT crop machines are covered separately in the GregTech entry for this rework.
    • Told in Crops NH
  • GT5-Unofficial #7919 Fixed a critical bug that could permanently corrupt the GregTech ore generation pattern file, which likely caused many unexplained oregen issues.
    • What to do: Run /gt oregenpattern once after updating: it prints your world's ore vein pattern and where that value came from. If it says AXISSYMMETRICAL for a world made after July 2023, or that the pattern was guessed, fix it with /gt oregenpattern set EQUAL_SPACING confirm. Veins that already generated do not move, so do not regenerate chunks. Note that 2.8.4 misreads the upgraded file if you downgrade later.
    • Told in Bug Fixes
  • GT5-Unofficial #5771 Completely reworked CAL imprint and sliced circuit system to be NBT-independent and enum-based.
    • What to do: CAL imprints and sliced circuits are now NBT-independent; place an old item in a crafting grid to convert it to the new meta-id linked version, and re-do any AE2 patterns or autocrafting that produced or consumed the old NBT imprints, since the new ones are different item metas.
    • Told in Bug Fixes
  • GT5-Unofficial #5652 Integrated CropsNH mod functionality by removing IC2 fertilizer and liquid fertilizer references, along with obsolete UN fertilizers and the crop manager.
    • What to do: Crop Harvestors and the EV and higher Crop Gene Extractors, Synthesizers and Seed Replicators are converted to their CropsNH equivalents in place as your save loads. The LV, MV and HV Crop Gene Extractors and Crop Gene Synthesizers are deleted - placed ones turn to air and stacks turn to stone, so break and scrap them before you update.
    • Told in Crops NH
  • GT5-Unofficial #4984 Complete worldgen system refactor: unified ore vein generation in GT, moved asteroid generation to Galacticraft, removed ore tile entities, improved NEI vein discoverability, and fixed bartworks vein information display.
    • What to do: GT and Bartworks ore blocks are converted in place by Postea as each chunk and each inventory loads, and GT++ ores are left exactly as they are. Do not dig out or remove ore blocks yourself. Chunks that already exist keep their veins; the new vein and asteroid layout appears in freshly generated terrain. Addon authors: the ore tile entities and ore APIs are gone, see gregtech.common.ores.
    • Told in Highlights
  • NewHorizonsCoreMod #1576 Block registration has been simplified, removing the tile. prefix from block IDs and updating how blocks are registered.
    • What to do: Back up your save. CoreMod block registry names lose their tile. prefix; placed blocks and the stacks in your inventory are converted for you on first load. Only custom scripts, configs or resource packs that hardcode dreamcraft:tile.<name> need editing.
  • NewHorizonsCoreMod #1557 Major refactoring of item registration system: most items now registered without YamCore, item registry names changed from dreamcraft:item.name to dreamcraft:name, and localized tooltips added.
    • What to do: Back up your save. Every CoreMod item registry name changes from dreamcraft:item.<name> to dreamcraft:<name>, and your stacks are converted for you on first load. Only custom scripts or addons that hardcode the old names need editing.
    • Told in Changes & Reworks
  • SGCraft #27 Stargate ring blocks now correctly form across chunk boundaries.
    • What to do: No step is needed before you update, and relogging does not fix this and never did. If you already have a Stargate whose ring is stuck partly unformed, where some ring blocks render as plain blocks and will not open the gate screen, break the Stargate Base block once after updating and re-place it; the ring then forms and stays formed. Gates built or rebuilt on 2.9.0-beta-3 keep their ring across chunk boundaries.
    • Told in Bug Fixes

Rebuild required (6) ​

A machine you have already built stops working until you rebuild it.

  • GT5-Unofficial #7468 Removes durability from photolithographic masks and replaces the focus input bus with a regular input bus on the Target Chamber, allowing masks to stack and work with stocking input buses.
    • What to do: Your Target Chamber will not re-form until you rebuild one block: break the Focus Input Bus in the top centre casing and put a normal Input Bus there, so the machine has two. The Focus Input Bus is now unused. Masks no longer wear out and stack to 64, but a part-used mask matches no recipe after updating. Recipes are batched per mask now: one run takes a mask plus 100 target items, 75 for the Living Crystal Chip.
    • Told in Balance
  • GT5-Unofficial #7029 Fixed structural symmetry issues in BEC Storage, BEC Assembler, Assembly Complex, and Forge of Gods: added missing glass blocks, removed asymmetric archway, and aligned ring sections.
    • What to do: Symmetry fixes unform your existing Antimatter Forge, Antimatter Generator and Forge of Gods rings - a few casings moved or changed type, so rebuild those sections against the new structure hologram. BEC Storage, the BEC Assembler and the Assembly Complex changed too, but those exist only in 2.9 dev worlds.
    • Told in Bug Fixes
  • GT5-Unofficial #6557 Implements diagnostics system across all multiblocks, fixing Space Mining Module disconnection crashes and Superconductor splitter module input handling.
    • What to do: Superconductor splitter modules now take a single input hatch: a module built with more than one no longer forms, so remove the extras and rebuild it.
  • GT5-Unofficial #6191 Fixed symmetry handling for 2-block tall flowers in the Mega Industrial Apiary, ensuring structural layout matches intended design.
    • What to do: Rebuild the Mega Apiary: three symmetry fixes (#6153, #6183, #6191) changed its structure layout, and the shape in this release is the final one.
    • Told in Changes & Reworks
  • GT5-Unofficial #5608 Algae Pond completely overhauled: tier system fixed, parallels reduced from 2 to 1, structure requirements clarified (75 sterile casings minimum, not 64), and recipes ported to RA2 with new NEI handler.
    • What to do: The Algae Pond floor now needs at least 75 machine casings, up from 64, and that applies to the old controller you already have standing. The floor has only 80 usable positions and hatches do not count, so a pond with more than five hatches or buses unforms on load; take the extras out or rebuild it. Parallels also drop from 2 to 1. Both controllers are called Algae Farm in game.
    • Told in Changes & Reworks
  • GT5-Unofficial #4982 Complete overhaul of High Temperature Gas-Cooled Reactor (HTGR): now provides alternative Europium and Americium fusion recipes, enables breeding of advanced materials, retiered to IV, and features dynamic fuel consumption and helium loss mechanics.
    • What to do: You have to rebuild your old HTGR. The reactor is a completely new and much larger structure made from casings that did not exist in 2.8.4, so take the old one down and build the new one from the NEI preview when you get there. It now runs at IV instead of LuV, needs a helium loop that slowly leaks, and takes new TRISO fuel. Your old TRISO and BISO pebbles are not removed and can be centrifuged back down.

Read before updating (10) ​

What you have to do depends on your base. Read these before you update.

  • ForgeMultipart #47 Fixed a critical issue where microblocks were randomly transforming into Blood Rune slabs.
    • What to do: No step is needed before you update, but do not expect a repair. Microblocks that already turned into Blood Rune slabs in a singleplayer world are permanently changed on disk and have to be broken and put back by hand. From 2.9.0-beta-3 on, no further microblocks are converted, and a microblock whose material is genuinely missing shows the purple-and-black missing texture instead of silently becoming a Blood Rune.
    • Told in Bug Fixes
  • GT5-Unofficial #6602 TecTech multiblock parameters were redesigned for ModularUI2, and the parametrizer card was ported to the new system.
    • What to do: OpenComputers programs that drive a TecTech multiblock, including every Space Elevator module, have to be rewritten. The tt_machine component addressed a parameter by hatch and slot number in 2.8.4, through setParameters(hatch, slot, value) and getParameters(hatch, slot); a parameter carries a name now, so setParameter(name, value) writes one, and getParameters() takes no argument and hands back a table of them all. On the Space Miner the names are distance, parallel, cycle, cycleDistance, range and step, and the overdrive and mode settings it had in 2.8.4 are gone. Computronics 1.9.10 is what carries the new component, so both mods have to come from 2.9.0 together.
    • Told in The ModularUI2 port
  • GT5-Unofficial #5833 Machine scanner output is now assembled from translation keys so the client can show it in the reader's own language, instead of being built into finished text on the server.
    • What to do: OpenComputers programs that read a GregTech machine through an Adapter have to be rewritten. getSensorInformation() used to hand back finished, coloured text; it now hands back the untranslated keys the client turns into that text, so a line that read "Efficiency: 100 %" arrives as GT5U.multiblock.scanner.efficiency with its arguments appended after it. GregTech's own scanner and its metrics cover were taught to decode this, but the Computronics bridge passes the strings straight through. Two further traps for anything that indexes the array: a line is emitted only when it applies, so a stopped machine hands back fewer entries than a running one and every position after the gap moves, and numbers now arrive with thousands separators, switching to exponential notation above a trillion, which defeats tonumber(). Around 160 machines are affected, GregTech, TecTech, GT++, GoodGenerator, Bartworks, KubaTech, KekzTech and the Space Elevator among them.
    • Told in OpenComputers
  • GT5-Unofficial #5820 Removed the Poo Collector machine and all associated content.
    • What to do: Poop line and Poo Collector machine removed; farms using this for agricultural chemistry or coal tar will need alternatives.
  • GT5-Unofficial #5595 Removes the duplicate imposter Zirconium material that has been deprecated for years.
    • What to do: This only matters if your world is very old. The deprecated duplicate Zirconium material is gone; it could not be obtained at all in 2.8.4, so only worlds carried over from several versions back can hold any. Those dusts and ingots become nameless unusable stacks rather than being cleanly removed. The real Zirconium is untouched.
    • Told in Removals
  • GT5-Unofficial #5027 Implemented IItemSource and IItemSink interfaces on GT machines and ported item movement code to use the new ItemTransfer system; item pipes are non-functional pending a separate PR.
    • What to do: Item pipes will not function until the follow-up PR implementing the new ItemTransfer behavior is merged; do not update to this version alone.
  • GT5-Unofficial #4970 PCB Factory upgrades are now separate sub-multiblocks that can be linked to a main PCB Factory using a data stick.
    • What to do: Your PCB Factory keeps its shape and does not have to come down. A bio chamber or cooling tower that was working in 2.8.4 stays linked and goes on working. From now on new upgrades are built as their own multiblocks and linked with a data stick, so if you ever tear the old cooling tower down you will have to build the new standalone version to get overclocking back.
    • Told in New Content
  • Nutrition #37 Major backend rewrite of nutrition storage and synchronization.
    • What to do: Player nutrition data is rewritten to server-sided storage; existing nutrition state may reset or change on first load.
  • OpenComputers #169 Major refactor adding full fluid and essentia support to AE2 integration through the new StackAPI.
    • What to do: OpenComputers programs that write ME Interface crafting patterns will error after updating: setInterfacePatternInput and setInterfacePatternOutput now take the pattern index as the second argument (slot, index, database, entry, size) instead of the last. Swap the order in your scripts. Nothing else changed: the store, clear and essentia calls are the same, and the AE fluid support is new.
    • Told in OpenComputers
  • Thaumic_Exploration #57 Fixed critical Soul Brazier exploit allowing permanent warp deletion, resolved client crashes on Vis Relay connection, and improved block particle loading and error messaging.
    • What to do: No step is needed before you update. If you have permanent warp parked in a powered Soul Brazier, it now comes back to you when the brazier runs dry or is broken, even if you are offline at the time. On 2.8.4 that warp was silently erased instead, so do not count on the brazier as a permanent warp remover any more. Warp already erased that way stays erased.

Check your build (17) ​

Probably nothing, but worth looking at the affected part of your base.

  • Angelica #1412 Upgraded rendering backend to target OpenGL 3.3 core profile with emulation of the fixed function pipeline, enabling compatibility with modern systems.
    • What to do: Angelica now emulates the fixed-function pipeline on an OpenGL 3.3 core context, so mods that use it keep rendering. Check your custom shader packs and any GL-heavy addon by re-testing them; no config file has to be edited.
    • Told in Angelica 2.x
  • Angelica #1221 Angelica 2.0 alpha release introducing Celeritas rendering engine integration, Iris shader support, dynamic lighting improvements, and removal of Sodium 0.2 dependency.
    • What to do: Client-side only: nothing in your world changes. Check your custom Iris shader packs by re-testing them against the Celeritas renderer; your angelica-options.json is migrated in place by ConfigMigrator.
    • Told in Angelica 2.x
  • Applied-Energistics-2-Unofficial #953 Fixed crafting calculation using incorrect substitute items when patterns accept oredict equivalents.
    • What to do: Check your crafting CPUs for a job stuck on a substituted ingredient, cancel it and re-request it; the calculator now tests that a substitute is actually accepted by the pattern slot. The patterns themselves do not have to be re-encoded.
    • Told in Applied Energistics and its addons
  • Et-Futurum-Requiem #37 Lava now pushes players and mobs sideways the way flowing water does, and dropped items float to the top of water and lava instead of sinking.
    • What to do: Check your builds that move items on water or lava. Items that used to sink and sit on the bottom ride on the surface instead, and they travel faster, so a water stream feeding a hopper, an item elevator or a lava trash pit can overshoot or drop its load somewhere else. Check your lava builds too: lava drags players and mobs along now, which it did not do before. Two switches in config/etfuturum/mixins.cfg put it back: liquidItemFloat turns off the floating on its own, and adjustedLiquidPhysics turns off the lava push, the faster items and the scaling by how full the block is. Turn off both for exactly the old behaviour.
    • Told in Changes & Reworks
  • GT5-Unofficial #7576 Rebalanced the Mega Distillation Tower (MDT) and Dangote to give MDT a competitive use case.
    • What to do: Dangote (the Advanced Distillation Tower) is about 14% slower in distillation-tower mode, a 3.5x speed bonus dropping to 3x. Check your Dangote lines: they keep running, just at reduced throughput.
    • Told in Multiblock structure rework
  • GT5-Unofficial #7299 Standardized multiblock construction tooltips across all machines: changed dimension format from (WxHxL) to (LxWxH), unified structure error order, standardized hatch/casing requirements, removed TecTech mentions, and added master channel descriptions.
    • What to do: Check your existing Large Turbines, Large Chemical Reactor, Electric Compressor, Fusion Reactors, Industrial Arc Furnace, Spinmatron, DTPF, Accelerated Biological Coordinator and Eye of Harmony. Each of those now tests for hatches it never tested for, and one that is missing stops the structure forming until you add it.
    • Told in Changes & Reworks
  • GT5-Unofficial #7025 Complete borosilicate glass system refactor: new rendering system uses standard block rendering instead of baked CTM, brand new textures for all tiers, and addition of a new UXV glass tier.
    • What to do: Every borosilicate block already placed, and every one sitting in a chest, is converted when the world loads, so none of it has to be crafted or put back by hand. Cosmic Neutronium glass becomes Infinity glass and old Infinity becomes Transcendent, which hands you a free tier of material. Coloured borosilicate is gone: those blocks come back as plain borosilicate. Two tier requirements did move, so check your build if you are past UMV. The multis that capped glass at UMV now want UXV glass for UXV energy hatches and lasers, and Exo-Foundry Containment Glass counts as UHV instead of UEV, so a UEV structure built from it stops forming.
    • Told in Highlights
  • GT5-Unofficial #6908 Windmill multiblock ported to ModularUI2 with major usability improvements.
    • What to do: Your windmill keeps its shape and stays formed. Check your build only for where it stands: wind speed now sets the parallel count instead of the recipe speed, and the machine stops with a maintenance error when the wind is non-existent or too strong, so a windmill in a very windy or dead-calm spot may sit idle where it used to run.
    • Told in The ModularUI2 port
  • GT5-Unofficial #6166 The Compact Cyclotron is being deprecated.
    • What to do: Check your Compact Cyclotrons: they keep running and their recipes stay registered for this cycle, but the COMET controller can no longer be crafted, so plan the move to the Large Hadron Collider before 2.10.
    • Told in Highlights
  • GT5-Unofficial #5320 Completely ported Drone Centre to ModularUI2 and refactored sync logic to fix long-standing range issues.
    • What to do: Check your Drone Centres after updating: the links re-establish themselves and the old "out of range" bug is fixed, but any custom name you gave an individual drone connection is dropped and needs retyping.
    • Told in Multiblock structure rework
  • NewHorizonsCoreMod #1921 Black plutonium wire cable loss increased from 8 to 32 EU/m to rebalance UXV-tier cable costs.
    • What to do: Bare Black Plutonium wire now carries 32 EU/m of loss instead of 8. Check your UXV runs: anything on uninsulated wire needs insulating, since insulated cable is still 8 EU/m, or it burns four times the power. UXV hulls, energy distributors and diodes now take Black Plutonium cables, and UEV and UIV hulls one extra plate.
    • Told in Recipes, quests and progression
  • OpenComputers #211 Fixed Lua indexing in Applied Energistics 2 integration to use 1-based indexing (standard for Lua) instead of 0-based, with backward compatibility for Thaumic Energistics.
    • What to do: Check your programs that set an AE2 bus filter. Slots are counted from 1 now, matching the rest of Lua: getPartConfig and setPartConfig address the first slot as 1 where 2.8.4 addressed it as 0, on item import, export and storage buses and on the Thaumic Energistics essentia equivalents, so every explicit slot number in your programs moves up by one. A call that omits the slot argument behaves as it did.
    • Told in OpenComputers
  • OpenComputers #179 The Lapotronic Supercapacitor now reports correct stored and capacity figures to OpenComputers through a driver of its own.
    • What to do: Check your programs that read a Lapotronic Supercapacitor through an Adapter. The bank answers as its own component named LSC now, which outranks the generic gt_energyContainer it presented in 2.8.4, so a lookup for gt_energyContainer on an LSC finds nothing and one for LSC finds it. The stored and capacity numbers were wrong on an LSC before and are right now, and getStoredEUString and getEUCapacityString hand back the full figure as a string for banks too large for a long.
    • Told in OpenComputers
  • OpenComputers #175 Fixed GeolyzerEvent to return correct metadata values for GregTech machines instead of block rotation data.
    • What to do: Check your programs that call geolyzer.analyze on a GregTech machine. The result gained machineType, metaId and gtMetaId, and its sensorInformation comes from the machine itself now, so only a real GregTech tile entity carries it and a non-GregTech block that answered through the same capability in 2.8.4 hands back nothing. Those sensorInformation strings are untranslated keys now, in the format described under the scanner refactor.
    • Told in OpenComputers
  • OpenComputers #163 Fixed Blood Magic integration returning incorrect sacrifice multiplier value.
    • What to do: Check your programs that read a Blood Magic altar through an Adapter. getSacrificeMultiplier handed back the altar's capacity in 2.8.4, which was simply the wrong number, and it hands back the actual sacrifice multiplier now. Anything that leaned on the old reading as a stand-in for capacity has to ask for capacity instead.
    • Told in OpenComputers
  • ProjectRed #60 Fixed Auto Crafter matching items by NBT tag as intended.
    • What to do: After updating, check your Auto Crafters. An Auto Crafter only accepts ingredients whose NBT tag matches the plan exactly now, so any crafter that was quietly being fed a differently tagged item, renamed, enchanted, or carrying any other NBT, stops producing without an error. Re-make the plan using the exact item you actually feed it.
    • Told in Bug Fixes
  • TinkersConstruct #279 Removed the Tinkers' Inventory GUI tab and moved heart canisters, travel belt, and travel glove to Baubles slots.
    • What to do: The pack now ships with the Tinkers inventory tab switched off, so Heart Canisters, the Travel Belt and the Travel Glove are pushed out of it into your inventory or onto the ground the first time you log in. Check your character after updating and re-equip them in Baubles slots: Heart Canisters stop granting their extra hearts until you do, and per Baubles rules they now drop on death.
    • Told in Tinkers' Construct

Config (2) ​

A config file changes. Check it if you have edited that file yourself.

  • NewHorizonsCoreMod #1895 Fixed multiple recipe conflicts: Spatial Network Relay now uses C3, pickaxes/axes use unified circuits (C19/C20), EV Compressor uses C2, and the Stripped Infested Nether log extruder recipe now converts infested logs correctly.
    • What to do: Tool crafting recipes consolidated (pickaxes to C19, axes to C20); recraft tools if using old recipe slots. Spatial Network Relay conflicts with Wireless Connector; check configurations.
    • Told in Recipes, quests and progression
  • OpenComputers #215 Made clipboard signal batching feature opt-in via configuration to maintain backward compatibility with existing scripts and setups that depend on the original per-line signal behavior.
    • What to do: If you have edited the OpenComputers config file, the maxClipboard key is gone and maxClipboardSize takes over from it, defaulting to 65536, so a value you set under the old name is ignored. Two keys join it: enableClipboardBatching, off by default so paste behaviour matches 2.8.4, and clipboardBatchSize.
    • Told in OpenComputers

Recipes changed (32) ​

A recipe you use is different now. You find out the next time you craft it.

  • GT5-Unofficial #7635 Dragonblood recipe balance adjusted: Mixer recipe duration increased 3x to 2100s, and DEFC coil tier requirement reduced from T3 to T2.
    • What to do: Nothing you built has to come down. The non-magic mixer route to molten dragonblood now takes 2100 seconds instead of 700, so an existing line produces a third as much per mixer; add mixers if you depend on it. The Draconic Evolution Fusion Crafter recipes for dragonblood now accept a tier 2 casing instead of tier 3, which only makes them easier.
    • Told in Balance
  • GT5-Unofficial #7569 Removed the ability to saw unstable ingots into nuggets, closing an exploit that bypassed the intended trade-off (1 diamond for full ingots vs 9 diamonds for nuggets).
    • What to do: After updating, the crafting table recipe that turned one unstable ingot into 8 unstable nuggets with a saw is gone. If you had that recipe encoded in an autocrafting pattern, delete or re-encode it. An alloy smelter with a nugget mold splits one unstable ingot into 9 nuggets as before.
    • Told in Balance
  • GT5-Unofficial #7428 Eternity and Magmatter nanites now cost more Universium nanites to craft, making them genuine late-game bottlenecks.
    • What to do: Nothing you built has to come down. If you produce Eternity or MagMatter nanites, re-plan the cost: one Eternity nanite per run instead of four, using two Universium nanites, eight Eternity blocks and 64000 L of primordial matter each; MagMatter nanites now take four Universium nanites instead of one. Re-encode any autocrafting patterns for those two nanites, for the Nanite Framework and for the MHDCSM implosion recipe, which all changed inputs.
    • Told in Balance
  • GT5-Unofficial #7373 Reduced Shirabon processing times and removed direct crafting recipes for IV+ tier material components (foils, gears, etc.).
    • What to do: Crafting table recipes for materials at tier IV and above are gone: plate from ingot, foil from plate, sticks, rings, screws, gears, small gears, rotors, dust to and from small and tiny dust, gem splitting and small pipes. Re-encode any autocrafting pattern that used a hammer, file, saw or wrench on those materials. Shirabon also processes about five times faster.
    • Told in Balance
  • GT5-Unofficial #6963 Integrated Eye of Harmony recipes into BEC (EM2 integration), replacing some Dyson sphere materials with tier-appropriate equivalents.
    • What to do: Every Eye of Harmony component recipe, the reinforced temporal and spatial casings, the infinite spacetime boundary casing and all tiers of the three field generators, has moved off the Research Station assembly line into the Bose-Einstein Condensate assembler. An existing assembly line for these parts finds no recipe, so build the BEC first.
    • Told in Bose-Einstein Condensate multiblocks
  • GT5-Unofficial #6342 Completely reworks Industrial Arc Furnace with three operating modes (Normal, Blast, Ore), new electrode system, and recipe adjustments.
    • What to do: Put a programmed circuit 1 in every arc furnace: the plain arc recipe no longer takes oxygen and will not run without it, and the gas and plasma variants need circuit 11 alongside their fluid. This hits single-block Arc Furnaces and both multiblocks; nothing is voided, the machine just idles until the circuit is there. Your existing Industrial Arc Furnace keeps forming as the deprecated Legacy controller; the new electrode-driven multiblock is a separate machine.
    • Told in Multiblock structure rework
  • GT5-Unofficial #6263 Rebalanced RC Water Tank recipe to make it more valuable as the water pump has made it obsolete in late Steam Age and early LV.
    • What to do: You do not have to touch anything you built, and water tanks you have already placed go on working. The GT assembler recipes for the Railcraft water tank block are gone, so an AE2 pattern or an automated line feeding that assembler recipe stops producing until you point it at the new recipe.
    • Told in Balance
  • GT5-Unofficial #5669 Deprecated the wire extruder mold and removed its uses throughout GT5U.
    • What to do: The Kevlar Spinneret assembler recipe now takes 16 Extruder Shape (Rod) instead of 16 Extruder Shape (Wire) - fix that pattern. The wire mold itself is not removed and remains usable in the Extruder; only the White Dwarf version can no longer be crafted.
    • Told in Changes & Reworks
  • GT5-Unofficial #5668 Moved the Forge Hammer space/time recipe from Forge Hammer to the Spinmatron's heavy mode for thematic consistency.
    • What to do: The Forge Hammer recipe that splits molten SpaceTime into Space and Time is gone. It moved to the Spinmatron (new in 2.9.0) in Heavy mode, which needs a T3+ structure and 16x the EU of the other modes. Any Forge Hammer line feeding SpaceTime stalls until you build one.
    • Told in New Content
  • GT5-Unofficial #5665 Added 256A Dynamo Hatches for UV-UXV tiers to reduce the need for stacking multiple 64A hatches.
    • What to do: Multi-amp energy and dynamo hatch assembler recipes (4A, 16A and 64A, EV through UXV) now take tier-appropriate molten metals instead of Silver, Electrum and Tungsten. Re-scan or re-make your stored crafting patterns for these hatches before you queue any. The new 256A dynamo hatches are additive, UV through UXV.
    • Told in Highlights
  • GTNH-TC-Wands #31 Crafting a wand, staff or sceptre now needs the Thaumonomicon research for both the rod and the caps you are using.
    • What to do: If a wand recipe will not complete in the arcane workbench after the update, nothing is broken: you are missing research. Look up the rod you are using and the caps you are using in the Thaumonomicon and finish both. With Salis Arcana installed the workbench shows you which of the two is missing. Wands you already own are untouched and keep working.
    • Told in Changes & Reworks
  • NewHorizonsCoreMod #1944 Fixed an enderium base dust mixer recipe that allowed platinum duplication.
    • What to do: The Enderium Base Dust mixer recipe now takes 2 Silver and 2 Platinum (was 1 and 1) for 6 output (was 4). Update the AE2 pattern or the dust feed ratio; the old 2:1:1 recipe is gone and the line will stall until you do.
    • Told in Multiblock structure rework
  • NewHorizonsCoreMod #1920 Dyson Swarm Module recipes are now significantly cheaper and use UIV-tier optical circuits instead of UMV pico circuits, moving Dyson progression to early UIV rather than late-game.
    • What to do: Dyson Module recipes rebalanced and retired from UMV to UIV; existing UMV modules remain functional but cannot be crafted using old recipes.
    • Told in Recipes, quests and progression
  • NewHorizonsCoreMod #1911 Adds recipes to reform duplicate vanilla and EFR music discs using disc fragments and thematic materials.
    • What to do: Turning music discs into Avaritia record fragments moved from the Macerator to the Forge Hammer and is now one recipe covering every disc - repoint any automated fragment line. New forming-press recipes let you trade duplicate vanilla and EFR discs for the disc you want.
    • Told in Recipes, quests and progression
  • NewHorizonsCoreMod #1899 Fixed an exploit allowing TCon ingots to produce Dense Obsidian Plates in 9 seconds instead of the intended 180 seconds.
    • What to do: The unintended 9-second Dense Obsidian Plate bending recipe is gone and the 180-second one is now the only path. Plates you already made stay valid - re-check throughput on any line balanced around the fast recipe.
    • Told in Recipes, quests and progression
  • NewHorizonsCoreMod #1855 Angel Ring recipe reworked to shift from ZPM tier to IV tier with new magical mod components.
    • What to do: Angel Ring recipe changed from ZPM to IV tier; existing ZPM-crafted rings remain usable but cannot be crafted the old way.
    • Told in Recipes, quests and progression
  • NewHorizonsCoreMod #1833 Stargate components are rebalanced with significantly increased costs, particularly in circuits and materials, to extend gameplay across the newly introduced BEC and NAC mechanisms.
    • What to do: Stargate block, upgrade and component recipes were recosted around BEC and NAC across 44 files. Re-check every assembling-line pattern you have stored for gate parts; nothing already built stops working.
    • Told in Recipes, quests and progression
  • NewHorizonsCoreMod #1801 Borosilicate glass recipes have been corrected to use UHV Neutronium Glass instead of the removed Cosmic Neutronium Glass, and waterline glass recipes have been fixed.
    • What to do: The Hawking Radiation Realignment Focus recipe now takes Transcendentally Reinforced Borosilicate Glass instead of Infinity Reinforced; update that waterline pattern. Nothing has to come down: the Exo-Foundry and Nanochip glass fixes only touch machines introduced in 2.9.0.
    • Told in Nanochip Assembly Complex
  • NewHorizonsCoreMod #1756 Updated 3 recipe definitions to reflect a structure rework.
    • What to do: The Clarifier Purification Unit and Antimatter Generator assembly-line research items, and one Nanochip recipe, now call for the new Large Sifter, Large Naquadah Reactor and Cryogenic Freezer controllers. Convert the old controllers with the NEI migration recipe first, or the research will not scan.
    • Told in Multiblock structure rework
  • NewHorizonsCoreMod #1755 SLAM controller recipe now requires UIV superconductors instead of UMV, increasing the crafting cost and progression tier required.
    • What to do: The SLAM controller recipe now takes a UIV superconductor instead of a UMV one. Nothing you have already built or crafted changes; update the assembling-line pattern if you have one saved.
    • Told in Recipes, quests and progression
  • NewHorizonsCoreMod #1739 Fixed a dupe exploit in the LCR (Large Chemical Reactor) where potassium hydroxide could be converted to rock salt with chemically incorrect ratios, causing net gains of potassium and losses of chlorine.
    • What to do: The LCR recipe turning potassium hydroxide into rock salt was corrected to 3 KOH = 2 KCl, closing a dupe. Re-check any automation balanced around the old output amount.
    • Told in Recipes, quests and progression
  • NewHorizonsCoreMod #1730 Updated turbine recipes to align with GT5-Unofficial structure changes.
    • What to do: Turbine crafting recipes now output the new reworked controllers, and the Spinmatron assembling-line recipe now takes 4 of the new Large Supercritical Steam Turbine instead of the old SC Fluid Turbine - update that pattern. Your turbines themselves need nothing.
    • Told in Multiblock structure rework
  • NewHorizonsCoreMod #1719 Updated recipe controllers to use new structure definitions after a refactoring of GregTech's multiblock controllers.
    • What to do: The Antimatter Forge and Antimatter Sequencer assembly-line recipes, and several Nanochip Assembly Complex recipes, now call for the new controllers: Naquadah Fuel Refinery, Advanced and Electric Implosion Compressor, Industrial Chemical Bath and Industrial Forming Press. Convert your stock with the shapeless migration recipes in NEI before you scan the research or run the line.
    • Told in Multiblock structure rework
  • NewHorizonsCoreMod #1713 Integrates new power ICs into high-tier recipes, replacing older QPICs and pico wafers with tiered variants.
    • What to do: High-tier recipes now use tiered power ICs instead of QPICs; adjust transformer, Dyson block, and solar panel builds to use new PIC variants. EBF infinite wafer recipe heat requirement lowered to 22kK.
    • Told in Recipes, quests and progression
  • NewHorizonsCoreMod #1712 Adds craftable recipes for new power ICs (FPIC, QPIC variants) that replace older components in high-tier recipes.
    • What to do: UIV and higher wafer cutting recipes move off the Cutting Machine onto the High-Intensity Laser Engraver, which needs the new BHC-made lens - repoint any automated wafer line. The bio wafer autoclave recipe also drops from 60s to 15s at UHV.
    • Told in Recipes, quests and progression
  • NewHorizonsCoreMod #1705 Plasma Arc Furnace recipes converted to use normal maps instead of specialized plasma maps.
    • What to do: Arc furnace recipes using plasma no longer tier-skip; chronic singularity crafting now requires UMV instead of UXV - adjust your build if you relied on UXV.
    • Told in Recipes, quests and progression
  • NewHorizonsCoreMod #1665 Three endgame recipes have been reworked to use containment units instead of particles.
    • What to do: Recipes using particle dust items now require containment units from beamcrafting instead - adjust your crafting sequence to obtain containment units first.
    • Told in Recipes, quests and progression
  • NewHorizonsCoreMod #1661 Added missing Stable Empty Containment Unit recipe required for beamcrafting progression.
    • What to do: The Stable Empty Containment Unit recipe is now available - use it to unlock beamcrafting. Craft Stable Empty Containment Units to progress past early beamcrafting gates.
    • Told in Recipes, quests and progression
  • NewHorizonsCoreMod #1614 Fixed NAC recipes using deprecated multiblock controllers after structure rework.
    • What to do: Two Nanochip Assembly Complex recipes now consume the new Industrial Wire Factory and Industrial Packager controllers instead of the old ones. Convert your stock and update your crafting patterns; the NAC structure itself is untouched.
    • Told in Multiblock structure rework
  • NewHorizonsCoreMod #1604 Removed IC2 crop references and moved crop-related recipes to the CropsNH mod.
    • What to do: IC2 crop recipes are removed; obtain crops through CropsNH integration instead. Use ore-dictionary substitutes for pam food crops where referenced in recipes.
    • Told in Crops NH
  • NewHorizonsCoreMod #1553 Replaces the Shaper machine with the Solidifier in core recipes and adds a conversion recipe to the Mass Solidifier.
    • What to do: The Fluid Shaper can no longer be crafted; that crafting recipe now makes the Mass Solidifier, and the Exo-Foundry assembly-line recipe wants 64 Mass Solidifiers instead. Convert existing Fluid Shapers with the shapeless recipe and update your patterns. A placed Fluid Shaper keeps running, but the controller is deprecated and goes away after 2.9.
    • Told in Highlights
  • RandomBoubles #6 Every combination ring infusion is laid out differently.
    • What to do: Look the recipe up in NEI before you start an infusion. The pearl has moved off the matrix onto a pedestal, so a setup built for the old layout is one pedestal short and the infusion will not start.
