Features and Improvements

• Unify structure definitions, port rules, and formation checks for native and addon multiblocks. Use the same definitions for previews, building tools, part appearance, and interactions; restore fluid-output backpressure and allow valid parts of formed structures to open their controller GUI. by @SaltNya (5d5948e)
• Update the Addon API to 1.3.0 with structure patterns, constraints, ports, and diagnostics, including KubeJS support. Deprecate legacy multiblock constructors and separate layout entry points while retaining compatibility for existing addons and scripts. by @SaltNya (5d5948e, 9edce83)
• Move fermenter brewing to vanilla potion items. Add a visible potion input slot with automation, multiblock-port, shift-click, and recipe-viewer support. Read brewing-stand recipes at runtime and register 39 additional GT ingredient routes with the brewing stand. Process one bottle per operation at 16 ticks and 256 EU, without potion-recipe parallelism. by @Tanimodori (ba754b3, 00320d1, 7f8b3dc, 2c7258a, ac72f0d)
• Remove the legacy potion-fluid system, including 94 potion fluids, the 490-row machine recipe table, associated drink entries, and potion bottling conversions. Remove poison bottles and buckets, fireproof crates and their bathing recipe, library night-vision cups, and related sandwich ingredients. Keep ordinary GT drinks; experience bottles in bottle crates now display green-tinted water. by @Tanimodori (c54848f, d0f9acd)
• Remove fermentation and its saved progress from sealed tanks. Retain soft-hammer sealing and block filling and draining while sealed. Preserve ordinary water-bottle filling and draining recipes and other bottle-container capabilities. by @Tanimodori (d0f9acd, 15b7cfd)
• Extend chromite generation in basalt strata to Y -16 through 64 and update the JEI / EMI worldgen display while retaining its existing generation chance. by @SaltNya (5d44ab4)
• Add wrench and screwdriver interactions for vanilla blocks: rotate or pick up pistons, dispensers, furnaces, chests, hoppers, and related blocks through the face grid; cycle pillar axes, dismantle workbenches and bookshelves, and rotate comparators and repeaters. Extend the applicable interactions to observers, barrels, and crafters while leaving paired double chests intact. by @lombinaxmasson (d027836)
• Add cached network routing to item pipes and optimize route searches and transfer scheduling to reduce repeated network traversal. by @lombinaxmasson (b9687c1, ab3d811)
• Optimize wire and fluid-pipe scheduling. Wires share network snapshots and use iterative traversal; completely idle fluid networks skip updates and wake when contents, covers, connections, or chunk state change. Add the performance.fluid_idle_scheduling option. by @lombinaxmasson (f24989c)
• Add configurable LOCAL, BALANCED, and SHARED fluid-pipe distribution modes with configuration explanations. Use LOCAL by default, and fix balanced distribution stalling beyond an intermediate pipe already at its target level. by @lombinaxmasson (f24989c, cf80825)
• Optimize recipe rebuilding on world load by indexing item forms and fluid definitions instead of rescanning entire registries for each row. Avoid expanding every tag candidate during conversion-recipe analysis, reducing repeated lookups and temporary allocations. by @lombinaxmasson (3b5028f, b6c3e1b)
• Remove the unused Aerotheum, Bedrockium, CrystallinePinkSlime, Cryotheum, and Unstable materials and associated content. Retain the Tritanium chain, restoring its End naquadah-processing byproduct routes that were removed during cleanup. by @Tanimodori (0bc950b, 0ebefb2)
• Remove dirty water, the WaterDirty material and alias, its bottles and wooden buckets, drying recipes, and related environmental effects. by @lombinaxmasson (d5a1fa2)
• Restore anthracite strata and their block using the Coal material, without reintroducing a separate Anthracite material. by @SaltNya (4d774dd)
• Remove Chalk, Dolomite, Gabbro, Gneiss, and Rhyolite materials and their associated stone blocks, decorative variants, ore backgrounds, and strata. Also remove the stone variants of Sylvite, Talc, and Oil Shale while retaining those materials and the oil-shale ore layer. by @SaltNya (4d774dd)
• Add migration for existing saves: replace retired stone blocks with vanilla stone and convert retired ore backgrounds to stone while retaining the ore. Map legacy material items to the corresponding Stone form where available, and update the material stored in old pebbles. by @SaltNya (4d774dd)

Bug Fixes

Recipes and materials

• Restore fluidized-bed combustion recipes that failed to register because they referenced the wrong molten-calcite identity. by @SaltNya (ce8595f)
• Restore sulfide-roasting routes using ordinary, End, and Nether air, plus missing sulfur and blaze variants. Correct sulfur dioxide and dust quantities and retain the original solid-output chances for air roasting. by @lombinaxmasson (f49534a, d75994e)
• Prevent plain-crafting replacement from deleting GT-generated recipes, restoring wire-size conversions, wire working, axles, and polymer forming. Deduplicate overlapping source recipes after registration to remove repeated wire, cable, and pipe entries. by @Tanimodori (115faae)
• Include plain Wood in the AnyWood family and allow GT wood-species sticks in the wooden-bolt hand-crafting recipe. by @lombinaxmasson (70bdeb1, 0396ed8)
• Restrict GT tool-crafting ingredients to supported GT tools so other mods' tools are not consumed merely because they share a tool tag. Preserve the existing tool compatibility checks for machine interactions. by @lombinaxmasson (59f16b0)
• Use the shared clay family in unfired-clay handwork recipes. Populate tier 7–9 circuit tags with registered processors and add English and Chinese tag names. by @SaltNya (1a93edd)
• Mark unported glue-bottle entries as optional so missing items no longer invalidate the entire glue tag and break glue-based crafting recipes. by @lombinaxmasson (3931cc5)
• Restore missing fuel values and burn products for lignite, peat, blaze, petrified wood, oil sands, oil shale, selected elements, and other retained fuels. Correct charcoal to produce Ash rather than Dark Ash. by @Tanimodori (0a5a71a)
• Restore Efrine and Firestone materials, forms, ore processing, and assets. Keep VoidQuartz and Gloomstone retired, leaving five Nether bedrock-ore entries. by @lombinaxmasson (d5a1fa2)
• Correct the melting points of Arsenic Bronze and HSS-E to 1357 K and 2367 K, respectively, and keep their generated molten-fluid temperatures consistent with the materials. by @Tanimodori (a5657e0)
• Limit vanilla replacement of iron, gold, copper, and netherite blocks to GT ingot blocks, preserving the separate GT solid-metal block forms. by @lombinaxmasson (2a4edf6)
• Register wire, cable, and signal-wire item compositions on both platforms, restoring contained-material tooltips and crucible recycling. Scale electrical wire and cable metal content by size and assign half a material unit to signal wires. by @Tanimodori (938b91d)
• Fix empty chest drops being rejected by crucibles because of redundant loot metadata. Accept known legacy metadata on empty chests and register the stone-shell composition of loot chests. Keep chests containing items or unopened loot protected from recycling. by @SaltNya (c558738)

Tools, items, and world interactions

• Preserve engraved mold patterns and other portable item settings when molds are removed or cover data is stripped, including the block-drop cleanup path. Ignore repeated chiseling of an already carved cell. by @lombinaxmasson and @SaltNya (82c0b37, 75640e7, 632b95b)
• Allow the anvil to split the workpiece on the other half when the clicked top half is empty. by @lombinaxmasson (615bbe7)
• Restore the mini Nether portal's collision shape and allow black sand to drop without requiring a tool. by @lombinaxmasson (5ed96c4, 435039e)
• Align the material enchantment table with original GT6 and complete the targeting and effects of Disjunction, Dissolving, Werebane, and Radioactivity. Support entity tags for additional ender, slime, and were-creature targets. by @SaltNya (21247a5)
• Prevent GT material tools from receiving additional enchantments through enchanting tables or books, matching GT6 while retaining their built-in material effects. Correct custom enchantment eligibility, incompatibilities, and availability; exclude Radioactivity and legacy placeholders from normal acquisition. by @SaltNya (21247a5)
• Complete material-arrow and bullet enchantment application, damage, Looting, and on-hit effects, and suppress the enchantment glint on material ammunition. by @SaltNya (21247a5)
• Restore automatic smelting of harvested drops with Fire Aspect III or higher. Migrate legacy tool and enchanted-book entries to their vanilla enchantment equivalents while preserving existing levels. by @SaltNya (21247a5)
• Fix strata-generated surface pebbles using the layer at the generation height cap instead of the actual exposed rock. Add eligible ore-indicator pebbles and clear carried ore information across caves and water gaps. by @SaltNya (4d774dd)

Machines, covers, and multiblocks

• Align automatic-hammer IDs, tiers, material names, recipes, models, and EMI groups with the Bronze, Steel, Titanium, and Tungstensteel variants. Fix stale Forge IDs aborting registration, leaving chemical batteries unbound, and preventing dedicated-server startup. by @lombinaxmasson (329c810, 9963917)
• Expose the full stored amount from mass storage so AE2 can list and use more than one stack. Let automatic output eject items into unobstructed space below. Hide sealed contents from automation queries instead of advertising items that cannot be extracted, and translate the automatic-output messages. by @lombinaxmasson and @Tanimodori (bab04aa, eae218c, 21baa7c)
• Expose sifting-table automation to hoppers and pipes: accept one valid recipe input at a time and allow output extraction. A player standing on the table can continue sifting after outputs are drained. Keep mortars and grindstones manual. by @Tanimodori (3d1e5f8)
• Refresh solar-panel sky visibility once per second, staggered by position, so distant roof changes update generation even without a neighboring-block update. by @SaltNya (ef8ccec)
• Prevent unloaded wire endpoints from repeatedly invalidating the network and interrupting delivery to other devices. Isolate visit tracking for nested energy transfers to avoid revisiting wires and endpoints when relays inject energy back into a network. by @lombinaxmasson (5c591cc, d6e2863)
• Preserve fluid-pipe wake timing so idle scheduling does not skip the current tick's second phase or the next queue position and slow fluid propagation. by @lombinaxmasson (d1a6d95)
• Connect item pipes to the output face targeted by a hopper nozzle regardless of placement order. Capture pipe placement faces only on the server so client prediction cannot change the server's connection choice. by @lombinaxmasson (4bfcc2c, 45917ed)
• Restore redstone-wire connections through a single solid conductor, including attenuation and port restrictions, without latching the signal after its source is removed. Correct powered-wire rendering and full-bright rendering for lit redstone-torch and repeater covers. by @SaltNya (7d33c2c)
• Fix RF / FE output from steam and other KU piston engines to other mods by exposing Forge Energy output connections. Preserve whole-stroke consumption when a receiver accepts only part of a piston stroke. by @SaltNya (4695deb)
• Prevent hoppers from filling every input slot of manual processing workstations with the same ingredient and blocking mixed recipes. Keep each ingredient in one input slot so other ingredients can be inserted. by @SaltNya (632b95b)

Smelting and fluids

• Fix crucible faucets ignoring the monkey-wrench automatic-input toggle, including the electric wrench's monkey mode. Reserve ordinary wrenches for rotation and soft hammers for redstone mode; pour once per second in automatic mode and on rising edges in redstone mode. by @lombinaxmasson (b287ecf)
• Stop crucible side interactions from blocking adjacent block placement. Place blocks above the vessel when targeting an inner wall and use the inner faces correctly for fluid interactions. by @lombinaxmasson (2fa3e40, 87d76d5, fccc498)
• Normalize fluids collected by drain covers and stored in tanks to their source identity. Fix natural gas and other fluids being split into separate source and flowing entries, including existing tank contents, while preserving amounts and attached data. by @SaltNya (1b8dde3)
• Restrict automated fluid extraction from processing workstations to outputs, while allowing held containers to recover unprocessed inputs. Rotate the first fluid output once per second so later outputs are not starved. by @SaltNya (632b95b)

Jade, GUIs, and rendering

• Unify Jade displays of actual input/output and device efficiency for engines, generators, turbines, and other energy converters. Read transfers from the last completed tick to avoid block-tick-order-dependent values, and standardize energy units and auxiliary-output displays. by @lombinaxmasson and @SaltNya (56f0b68, 8a2f2cf)
• Display the anvil's two workpiece slots separately in Jade instead of combining identical items from both sides. by @lombinaxmasson (eb21f44)
• Remove duplicate generic Jade item/fluid storage rows from burning boxes, placeable fluid containers such as pressure bottles, and machines with dedicated contents displays. Retain their contents displays and fluid bars. by @lombinaxmasson and @SaltNya (2c85b5a, 55e95cb)
• Use consistent compact fluid icons, amounts, and names for predicted recipe outputs and stored machine fluids in Jade, showing capacity where applicable. by @lombinaxmasson (dd0e78b)
• Light each large-crucible hull cell from its own neighboring block. Render ordinary crucible contents from a display snapshot so chunk-render threads no longer traverse the live, changing material list. by @lombinaxmasson (1d1031e, 7e205ac)
• Show a red Jade warning before dismantling a small crucible at 1300 K or above, matching its actual break-time meltdown threshold. by @SaltNya (ec4f153)
• Align machine GUI item slots with the original GT6 container layout, including affected screens such as the printer, and update the GUI preview tool to match. by @Tanimodori (8fffb96, 3a385d1)
• Complete the Trinium fluid cell's block and item models, name, and EMI grouping, and rename the incorrect fluid_cell_kreknorite registration to fluid_cell_trinium. by @lombinaxmasson (37cb053, 531d3bd, dbb6e60)
• Restore spectator crosshairs and block outlines for inspectable GT containers and machines, using the same allowed faces as the server. Block spectators from opening unopened loot chests and show Minecraft's standard loot-not-generated message. by @SaltNya (60ce1e2)
• Align engine tooltips with the common machine format, correcting energy colors, input/output ranges, efficiency, port directions, and capacities. Use dark gray tool-operation hints and remove duplicate descriptions. by @SaltNya (55e95cb)
• Restore capacity in machine GUI fluid-slot tooltips and use the fluid name instead of the "Fluid output buffer" heading. Show amount/capacity for filled slots, Empty/capacity for empty slots, and ∞ for output buffers without a fixed limit. Both amounts and capacities follow the mB / L setting in display.fluid_in_mB. by @SaltNya (2a08376)
• Remove verbose explanatory text from JEI / EMI vein pages. Display host-layer stones beside the minerals and add them to the recipe index so the associated veins can be found through those blocks. by @SaltNya (4d774dd)
• Add English and Chinese names for Disjunction, Dissolving, Werebane, and Radioactivity. Give legacy duplicate enchantments their corresponding Looting, Efficiency, Sharpness, and Smite names. by @SaltNya (21247a5)

Internal Changes

• Split vanilla composition loading into separate table, stone/copper correction, railing, and wood-species steps. Remove 92 empty composition entries for technical or entity items. by @Tanimodori (c05a19e, 0a67a0f)
• Clean up the retired HSLA fluid texture, duplicate ingot icons, dead potion recipes, and obsolete fireproof-wood and sealed-fermentation language keys. Explicitly mark selector-tag ingredients as non-consuming catalysts. Remove models, textures, blockstates, language entries, and recipe-data references belonging to retired stone content. by @lombinaxmasson and @Tanimodori and @SaltNya (f9e2516, 33f9a47, f7c4ba5, 4d774dd)
• Fix Gradle scripts used by IntelliJ IDEA, add a NeoForge mirror, and retain the official repository as a fallback for artifacts unavailable from the mirror. by @gangzhengzhiwei and @Tanimodori (7cb0def, 73814fa)
• Organize validation documentation by package responsibility and add a path-to-check lookup tool. Update Jade, storage, API, and potion-removal documentation, and clarify that comment scripts are on-demand diagnostic helpers. by @Tanimodori and @lombinaxmasson (194f291, ee2fd2a, 52158d9, 8b1016d)
• Expand regression coverage for networks, fuels, melting points, material compositions, recipe deduplication, machine slots, sifting tables, and multiblock APIs. Remove temporary network tests and a fixed-timing propagation test. Revert side pickup from casting basins, retaining the original top-only interaction. by @lombinaxmasson and @SaltNya and @Tanimodori (ab3d811, 5d5948e, 69f19c1, 48f36a5)
• Fix formatting-check failures in wire, recipe, and version-specific brewing code, and update the mod version to 1.0.5a. by @lombinaxmasson and @Tanimodori and @SaltNya (ef990f9, 7c4d808, f6eab25, 12c98c6, 5faab07)
