v5.1.16 (2026-08-20) — Mixed pipes

Supported versions: 1.21.9 - 26.2 (data pack formats 88 - 107).

Added

• Networks hold several media at once. Water, lava and steam can share a pipe run, each with its own entry, and the run clogs on the sum rather than on any one medium. A network used to refuse anything but what it already held, so a run was single-purpose for as long as it held anything at all. Nothing refuses an offer now except a lack of room.
• Liquid Filter. A Valve that passes only the medium it is set to, so a mixed run can be sorted back into single-medium branches. It levels per medium: two runs each holding 5000 mL are not level to a water filter if one is all lava.
• Potions keep their effects. A potion poured into a Drain is 1000 mL of the potion medium and the network remembers which potion. A Drain set to output applies it to everyone within four blocks, with the duration scaled by how much was drawn and the level the potion says it has. The first potion into a network keeps its identity.
• item_name properties, and [Set from hand]. A property holding an item id gets a second button that copies whatever you are holding. Nobody should have to spell minecraft:polished_blackstone_slab to configure a sorter.
• Big Torch. An end rod wearing a torch scaled to a full block tall, always standing up. Denies hostile spawns within 1-100 blocks, set with the Data Handler. It drops what spawned inside the radius into the void and leaves what walked in, by remembering every mob in a band 16 blocks past it — dropping rather than killing is what stops it being a mob farm that also lights the room. Built from Enchanted Coal — sacrifice coal on an enchanting table at 1% — nine of which make an Enchanted Coal Block, which over a stick makes the torch.

Changed

• The Big Torch drops mobs into the void instead of killing them, and its radius stops advertising a reach it does not have. A kill fires the death, so a torch in a dark room was a passive mob farm that also lit the room; a denied mob is now teleported out of the bottom of the world and nobody collects anything. The destination is deliberately not derived from min_y — void damage starts some distance below it and that distance is not the same across the versions this pack supports, so it goes far enough down that no supported dimension reaches it. The 100-block ceiling was applied to the working value but not written back, so a torch set to 500 swept 100 while the goggles and the Data Handler both said 500.

• Item Pipe filters are a property, not an item frame. Set with [Set from hand]; the goggles draw the item it is filtering for, above the id. Reading a filter used to mean an entity selector per pipe plus a block_pos comparison per candidate frame, cached and rescanned every 20 ticks — so a frame you had just hung did nothing for up to a second. It is now one data modify with no selector, no cache and no stale second. Existing pipes migrate; their frames are left alone.

• Tools no longer stack. Every tool is max_stack_size=1. They carry per-tool state — the Clipboard's origin, the Remote's channel — and two in one slot is a stack whose state belongs to whichever was picked up last. The bundles still hold the full set: bundle_contents set by a command is not subject to the weight limit that applies to inserting by hand.
• A network keeps its number. Ids used to be handed out 1, 2, 3… on every rebuild, so they said nothing about identity: break one run and every run numbered above it slid down one. The Multimeter would report "Network 22", the run would be torn out, and nets.n22 would still be sitting in storage afterwards holding somebody else's water — which reads exactly like a network that refused to die. A component that still contains the old network's root now inherits its number, anything genuinely new takes the next number a counter has never issued, and a retired number is never issued again.
• The Goggles say Multimedium; the Multimeter says what is in there. A billboard is one short line read from across the room, and Water 5000 mL, Lava 5000 mL, Steam 2000 mL is neither short nor legible at that distance — so a mixed run reads as Multimedium on the Goggles over the usual total, and the Multimeter prints a line per medium in chat, where there is room. A single-medium run still reads as its plain name, which is what the Data Handler and every single-medium block expect to read back.
• The Electric Furnace's top mode cost three EU Generators to run. 1000 EU an item at five ticks an item is 200 EU/t, or about twenty Solar Panels across a daylight cycle — priced out of the game rather than expensive. The table is now anchored on one EU Generator at 60 EU/t: 40/80/160/300 EU per item for low/medium/high/superpowered. Each step still costs more per unit of speed than the one below it.
• The Creative Fluid Source tops up at a rate instead of claiming the run. It offered the whole of the network's free space every tick, which is what a single-medium source wanted and exactly the wrong thing now that a run can hold several media: one source took the entire network on the tick it was placed — 100000 mL of water in one go — and every other source, Pump and Drain on that run then found a full network for ever. A mixed run could not be built anywhere one was attached, and it looked like the run refusing the new medium rather than like the source having already taken the room. It now adds rate mL per tick, 1000 by default and settable on the Data Handler, so sources sharing a run interleave.

Fixed

• A nameless total survived every rebuild, and renamed itself to whatever came next. rebuild/snapshot_read would carry a network's bare amount across a rebuild when it had no breakdown to carry, on the grounds that losing the contents silently was worse than losing their name. It is worse. The carried total had nothing to reconstruct amounts from, so the next rebuild carried it again, and the first medium offered afterwards became the only entry in media and therefore the name of all of it — 15000 mL of nothing reporting itself as 15000 mL of the next thing you poured in. Networks reached a state holding a five-figure amount with no medium at all, which neither migration could repair because both are gated on a medium those networks did not have. A rebuild now carries the breakdown and nothing else, and the total is summed back from it, so amount is always exactly the sum of amounts.
• The read-time migration could never fire on a network that needed it. It tested unless data ... media, and rebuild/reset_net writes media:[] — an empty list is present as far as if data is concerned, so a network holding an amount with an empty breakdown was never migrated. rebuild/snapshot_read made the same test as media[0] and got the right answer; the two disagreeing is what let the state persist.

• The Big Torch, the Magic Crate and the Breeder each duplicated their own block. All three killed the vanilla drop with a bare kill @e[type=item, ...,distance=..2] — no execute as @e[tag=ra.broken,...] at @s run in front of it — so the distance was measured from wherever the module's tick function stood rather than from the block that had just been broken. The end rod or barrel survived and was handed back alongside the custom item. Every other block in the pack already wrapped this correctly. The bare form also ran every tick, so any end rod or barrel item that drifted near the tick position was deleted.

• A rebuild collapsed a mixed run into one medium. Pour 5000 mL of water into a network, place a block — any block, anywhere on the run — then pour 5000 mL of lava in, and it reported 10000 mL of Lava. The rebuild that runs when the topology changes parked only the total and the primary medium's name on the network's root node; the per-medium breakdown was dropped, and because a fresh network is written with an empty media list rather than none at all, the read-time migration never fired to repair it either. Whatever was offered next became the front of the list and so became the name on the whole total. The breakdown is now carried through the rebuild in full, and the total is summed from it rather than read separately, so the two cannot disagree.

• A rebuild forgot which potion a network held. Same cause: potion lives on the network next to the amounts, and nothing carried it across. A potion run lost its effects the moment a block was placed anywhere on it.
• The Solar Panel made a twentieth of its stated output. It generated on a 20-tick duty cycle but kept the per-tick amount, so a panel peaked at 2.5 EU/t rather than the 50 EU/t the Electric Furnace's whole mode table is priced against. Twenty panels came to 50 EU/t at absolute noon, which an Electric Furnace on superpowered (60 EU/t) outruns for ever — so a base with twenty panels and two Batteries sat pinned at zero stored EU in full sun, with nothing visibly wrong. It offers what it makes every tick now. Batching it up instead would average the same and behave worse: a 1000 EU burst needs somewhere to land on the tick it arrives, and a panel contributes only 50 of capacity.
• The Solar Panel never showed its own output. Its readout was the grid's total, so there was no way to see the rate above from in game. It publishes Making: N EU/t beside the sun line, as the EU Generator already did.
• Transport Networks' figures. The Boiler was documented as 100 water to 100 steam per cycle; it moves 1000 mL each way, every 20 ticks. The capacity table put Pumps and Drains at 2000 mL when they hold 5000, and had no row at all for the Gas Tank, either Ender vault, the Electric Furnace or the Creative EU Source.
• The Data Handler's registry never reached an existing world. It was seeded lazily, unless data storage ra:dh numeric, from three call sites — so a world upgraded from an earlier version already had numeric, the guard passed, and the registry was never rewritten. It kept the old list, with no filter_item and no filter_medium in it and no item_names list at all, so neither filter had a row in the editor on any block. It is now written on every load, like the wrench and readonly registries beside it, and a name added to it reaches an existing world on the next /reload.
• The Creative Fluid Source's medium could only be set with the wrench. Its medium property was never in the Data Handler's registry, so it had no row — and neither did enabled, which the wrench toggles on emitters and multiblocks. Both are registered now. A medium typed rather than cycled is checked against the media registry before anything is pushed, because free text can name a medium that does not exist and a junk key in a multi-medium network is one nothing could ever drain.
• The Data Handler had no row for either filter. It draws a row only for a property the block actually has, and Item Pipes were placed carrying none at all, while filter_medium was never added to the registry. Pipes are now placed with an empty filter_item, existing ones get it from the migration, and both names are registered.
• The same item came out different depending on where it came from. Twenty items had lore that disagreed between the recipe, the give function, the namespace bundle and the block's own break drop — so a crafted Liquid Filter and a broken one were different items and would not stack. All four sources now agree, from the recipe.
• The Redstone Remote's recipe claimed Channel: default for ever. The lore line was static and set_channel is a copy_custom_data modifier that never touches lore, so a remote switched to another channel went on saying default. The line is gone.
• The up and down sides read every redstone source as 0. ra_lib:redstone/side substituted the back direction into a redstone_wire connection state, which has no up or down — so the macro line failed to parse and stopped the whole function before it ran. A lever sitting directly on a block never turned it on, and neither did a torch underneath or a redstone block on top. Every block using the library was blind above and below.
• The readme's counts. The subtitle claimed 52 blocks, 5 tools and 58 recipes while the badges beside it said 57, 7 and 66; the badges were right. The block and tool reference tables were short by four blocks and the Redstone Remote.

v5.1.15 (2026-08-19) — Settings

Added

• Settings. Two kinds, reached two ways. Server settings live under /function ra_settings:admin/ and autocomplete — a function path is the only command surface that does. Player preferences are /trigger ra.settings.open, which needs no permissions. /function ra:settings is the short way in.
• Blocks can be turned off, per type, with a page listing which and a warning on load. The item is handed back rather than swallowed, and anything already built keeps working.
• Defaults can be retuned — generator EU/tick, clock interval, vault rates, crate radius. Applied at placement, with [Apply to placed] to push a change onto blocks already standing.
• Sound and particle switches, per player. All 118 playsound and particle calls respect them.
• Uninstall warns twice and says what it is about to destroy.

Fixed

• Ender vaults could not find each other — the tag a sending vault searches for was cleared every tick and never set. Broken since v5.1.8, in all three vault types.
• The Electric Furnace flickered and z-fought while working; a working furnace was drawn as switched off for four ticks in five on superpowered; a steam-fed EU Generator ran while drawn permanently unlit.
• Jetpack upgrade kits fired with the jetpack off — in normal mode, jumping and sprinting gave you the Thruster for free — and kept working on an empty tank.
• Text input never completed anywhere it was used by the settings, because the session was opened at the wrong point in the tick.
• /trigger completion is no longer cluttered: nine blanket-enabled triggers down to one.

v5.1.14 (2026-08-18) — Pictures

Added

• Screenshots in the wiki. Transport Networks opens on a running EU grid and shows a fluid network, the Electric Furnace and the Industrial Light lit beside unlit; Jetpacks shows hover flight. Seven in docs/images/screenshots/.
• A banner per module in the README, with a generated docs/images/banners/media-missing.png placeholder for the ones that have no screenshot yet. Swapping a placeholder for a real picture is a one-line edit.
• An Industrial Light section in Transport Networks, which the page never had.

Fixed

• The README was stale in ways that mattered. It listed Netherite Liquid Pipe, Netherite Gas Pipe and Netherite Electric Wire as separate blocks — the tiers were removed, and those item tags now place the single version. It was missing eight Transport Networks blocks (Battery, EU Breaker, Industrial Light, Boiler, Solar Panel, Electric Furnace and both Creative sources), the Magic Crate, the three new jetpack kits, and the Clipboard and Multimeter. Counts corrected: 57 blocks, 7 tools, 66 recipes — the badges said 52, 5 and 58.
• Transport Networks still described tiered pipes in its Block Families table, and pointed at ra_wires:items/give_all, which does not exist. It now names the Wires Bundle and the creative give function.
• readme.bbcode regenerated from the corrected README.

v5.1.13 (2026-08-18) — Documented

Added

• Recipes for the Clipboard and Multimeter. Both shipped with a give function and nothing else, so in survival they did not exist.
• A Tools page, which the wiki never had. The Wrench, Goggles, Data Handler, Clipboard and Multimeter were described only in scattered module notes and the technical pages; the Clipboard and Multimeter had no usage documentation at all, only a row in the item table.
• Missing unlock advancements for the Battery, EU Breaker, Industrial Light, Boiler, Solar Panel — and the Wrench and Data Handler themselves — plus get_* advancements for the Battery, EU Breaker, Industrial Light, Clipboard and Multimeter. Those blocks were craftable but the recipe never unlocked itself.

Removed

• Three dead advancements: unlock_electric_wire_netherite and unlock_liquid_pipe_netherite, left behind when the tiered wires and pipes were removed, and unlock_conveyor, which pointed at a recipe and a block that do not exist anywhere in the pack.

Changed

• The wrench and Data Handler sections of How It Works described the old per-block dispatch and the goggles tinker. Rewritten for the registry-driven menu, including the stacked_prop_line / stacked_status_line / stacked_data_line distinction that silently renders N/A when you pick wrong.
• The Developer Guide now documents the migrations system and the read-only registry.

v5.1.12 (2026-08-18) — Depth

Fixed

• Skins z-fought with the block underneath. The overlay was scaled 1.004, leaving two thousandths of a block of clearance on each face. That is geometrically separate and practically not: Minecraft's depth buffer loses precision with distance, so a few chunks out both surfaces resolve to the same depth and flicker. The margin is now 1.02 — a hundredth of a block per face, five times the separation, and still about a sixth of a pixel of overhang on a sixteen-pixel texture, so nothing looks fat. Where a neighbour is solid the overhang is buried inside it and never drawn. ra_migrations:5.1.11-to-5.1.12 clears existing skins so they redraw with the new geometry — displays keep whatever transformation they were summoned with, and every skinned block already redraws a missing skin within a tick.

v5.1.11 (2026-08-18) — Read Only

Added

• One declaration for read-only properties, ra:tools/readonly/init_registry, keyed by block type. A property listed there is shown by the Data Handler with a struck-through [Modify] and a reason on hover, and is never offered by the wrench. Marking something the block owns — a generator's generation_rate, a valve's rate, a breaker's cooldown — is now one edit that both tools obey, instead of one tool knowing and the other not.

This replaces five per-module tools/hidden_fields.mcfunction files reached through a #ra:hidden_fields function tag, each a chain of tag tests — the same per-block-table shape the Data Handler registry was consolidated to remove. The set is stored as a compound rather than a list because both readers ask "is this name read-only?", which a compound answers in one command and a list needs a walk for.

Removed

• enabled from the Ender vaults, the Teleport Anchor and the Infinite generators. None of them had anything that could toggle it — no redstone, no wrench action — so it was a property you could set and then watch do nothing. It stays on the Wireless Emitter/Receiver and the Multiblock Base, which are toggled by the wrench's plain right-click and would have no control at all without it. ra_migrations:5.1.9-to-5.1.10 strips the dead copies.

Fixed

• The wrench filtered read-only entries after counting them, so a block whose only cyclable property was read-only would have cycled it silently on a plain shift-click instead of reporting that it does not cycle. The filter now runs first, and both the menu and the click path build the list through the same function — a button carries a row index, so a click path that built the list any differently would act on a different property than the one on screen.

v5.1.10 (2026-08-18) — No Second Switch

Fixed

• The Electric Furnace duplicated items — it smelted without consuming the input. When find_try was rewritten so every slot counts as input, the line that put the slot number into ef.hit went with it and only the score was left. take_input is a macro function reading ef.hit, so it had no $(slot) to substitute; a macro with a missing argument fails without running a single one of its lines, so nothing was removed and the #ef.took flag it was supposed to clear still held the 1 from the previous successful smelt. deliver ran on that stale flag and produced an ingot from an ore that was never eaten. The slot is back in ef.hit, and the caller now clears #ef.took itself, so a take that does not run can no longer read as a take that did.

Removed

• The enabled property, throughout ra_wires. It was a second off switch sitting next to redstone, on blocks that mostly had nothing else to configure — so the new wrench menu opened on a great many blocks just to offer one useless row. Breaking the wire does the same job and reads better. ra_migrations:5.1.9-to-5.1.10 strips it from existing markers so it stops appearing in the Data Handler as a property that does nothing.

Changed

• The EU Switch runs on redstone. It was the one block whose only control was enabled, which meant the only way to work a switch was to open a menu — in a redstone pack. Powered conducts, unpowered cuts, matching the EU Breaker and the valves, so a lever wired to it now does what a lever obviously should.
• Menu buttons are bold and spaced — [ CYCLE ], [ ON ], [ OFF ], [ REMOVE ] — so they read as buttons and are easier to hit.

v5.1.9 (2026-08-18) — One Tool

Added

• The wrench opens a menu on blocks with more than one setting. Shift+RMB still cycles immediately when a block has exactly one cyclable property — a menu with one button is a worse button — but a block with two or more now lists them with their current values and a [Cycle] button each.
• A cyclable-property registry, ra:tools/wrench/init_registry. The wrench used to be a chain of "if this block tag, run that block's cycler", which allowed exactly one setting per block; anything that wanted a second had to borrow another tool. A block now declares a list and the wrench works out whether to cycle or to open a menu. Adding a setting is an edit in one file.
• Markers record their block type in data.type, because the registry has to be keyed by something and a data pack cannot ask an entity which of its tags names its kind. ra_migrations:5.1.8-to-5.1.9 fills it in for existing worlds.

Removed

• The goggles tinker. Sneak+goggles used to cycle modes and toggle enabled, which meant two tools that both changed blocks with no rule about which owned what — the Electric Furnace ended up with its output on the wrench and its power mode on the goggles, and a wrench message addressed to a tag only the goggles ever set. The goggles read; the wrench changes. Everything the tinker did is on the wrench now, including the enabled toggle, which is a menu entry on every RA Wires block, and the Liquid Drain's drain/place mode.

v5.1.8 (2026-08-18) — Reach, Lift, Scorch

Three bugs that all looked like "the block just does nothing", and two new toys.

Added

• Creative EU Source and Creative Fluid Source (ra_wires) — make power and fluid out of nothing, for building and testing the consuming half of a system without also running a fuel farm to feed it. The EU source refills its grid to capacity every tick, so a machine on a creative grid never browns out; the fluid source fills with a medium cycled by the wrench, because a network holds one medium at a time and a source stuck on water could not test a lava line. No recipes, on purpose; both ship in the Wires Bundle, or /function ra_wires:items/give_creative for just the two.

Added

• An upgrade menu, /trigger ra.jp.kits. Lists the three kits with their state and two buttons each: switch one off without removing it, or take it off and get the kit back as an item. Re-shown after every action, so it behaves like a panel rather than a one-shot message.

Added

• Electric Furnace (ra_wires) — smelts with EU and no fuel at all, at up to forty times a vanilla furnace. Four power modes cycled with the wrench:

Mode	Ticks per item	EU per item
low	100	40
medium	50	100
high	20	300
superpowered	5	1000

EU per item climbs faster than speed does, on purpose — four times quicker for four times the power would make every mode but superpowered pointless.

Input and output are split by slot inside one barrel: the top row (slots 0–8) is input and is only ever read, rows two and three (slots 9–26) are output and are only ever written. Results are also pushed into any container directly below. That combination is what makes hoppers work with no configuration — a hopper feeding the block fills the lowest free slot, which is the input row, while extraction has to be a push because a hopper underneath would otherwise pull unsmelted ore out of slot 0. With nothing below, results stay in the output rows, so it still works as a standalone block you open by hand.

Added

• Every entity the pack owns now carries the plain ra tag, so /kill @e[tag=ra] sweeps up the pack and nothing else. A pack built out of markers, block displays and text displays has no other way to be cleaned up, and killing every marker and display in a world takes other people's builds with it. Worlds built before this are caught by ra_migrations:5.1.7-to-5.1.8 on load.
• A ra_migrations namespace, one function per version step, named for the step it bridges. They run oldest-first from ra:load, and every one runs on every load — so each must be safe to run twice and may only fill in what a newer version expects, never overwrite. (-to- rather than ->: a resource location path may only contain [a-z0-9_.-/], and a file with > in its name is skipped by the datapack loader.)
• Magic Crate — a barrel that reaches out and takes dropped items from up to 20 blocks away. radius (5–20) and cooldown are both editable in the Data Handler; the sweep takes at most eight items per pulse so a hopper standing over a mob farm never spikes the tick. Whole stacks cross verbatim, so names, enchantments and damage survive the trip. It refuses items on a permanent pickup delay, and drops its whole 27-slot inventory when broken.
• Jetpack upgrade kits, three of them, right-clicked while wearing a jetpack:
• Thruster — +45% movement speed, in both flight modes and on the ground.
• Lift — climbs at about six blocks a second instead of three, and sinks faster by dropping the slow-falling cushion.
• Scorch — sets fire to anything in a 3×3 column six blocks under your exhaust, with flame and lava particles. Players, dropped items, and every marker and display entity the pack is built from are excluded, so flying over your own base does not burn your machines down.

Fixed

• The wrench cycled the Electric Furnace's output in silence. Its message was addressed to @a[tag=ra.wires.tinker_user], which is the tag the goggles tinker puts on the player. The wrench never touches the player — it runs as the marker off a raycast — so the selector matched nobody. It now messages @a[distance=..10] like every other wrench action.

Fixed

• The Thruster never engaged in classic mode. It was gated on a speed floor of 0.18 blocks a tick, and in classic you fly by holding sneak — horizontal air movement never gets near that, because air control is a small fraction of walking speed. The floor was also the wrong idea in general: it cannot tell crossing terrain from lining up a block, since both can be slow. Hold sprint to engage it instead — an explicit input, meaning "go fast" the same way it does everywhere else in the game, identical in both flight modes, and nobody sprints while placing blocks, which is where the jitter was unwelcome.

Fixed

• Every Electric Furnace readout said N/A. The billboard library has both data_line, which reads data.status, and stacked_data_line, which reads data.data — different places behind near-identical names. The furnace wrote data.status and asked the stacked reader for it, so every value was simply absent and rendered as the fallback. Added the missing stacked_status_line and documented the four-way naming trap at the top of it. The Magic Crate's state line had caught the same edge.
• A switched-off jetpack kit could never be switched back on. kit/toggle removed the tag, then tested for it again on the next line — after its own removal — and put it straight back, so every click ended muted. Same shape as the Block Breaker cooldown bug: a condition re-tested after your own first line invalidated it. The state is now read into a score before anything changes it.

Fixed

• Standing on the edge of a block counted as flying, so the Scorch kit set fire to whatever was below a player who was, from their own point of view, standing still on solid ground. The airborne test sampled one point under the player's exact centre, which is over the drop when you stand on a block's edge while your feet are still on the corner. It now samples all four corners of the hitbox as well — a player is 0.6 wide, so +/-0.3 — and any one of them over something solid means supported, which is how vanilla decides it too. Shared by the Thruster, which had the same bug more quietly.

Fixed

• The Thruster kit did nothing you could feel. It raised minecraft:movement_speed, which governs walking: once you are off the ground, horizontal movement runs on a much smaller air-control factor, so the attribute was a lever that is barely read in flight. It now measures how far you actually moved last tick and adds 55% of it back, capped at 0.2 blocks a tick each way — so it accelerates rather than snapping to speed, pushes whichever way you are really going (strafing and reverse included), does nothing at all while hovering still, and fades on its own as air drag shrinks the delta. It refuses to push you into a wall, since tp does not collide.

Fixed

• The Scorch kit never set anything on fire. Its selector carried type=!boat, and there has been no minecraft:boat entity type since 1.21.2 — it was split into oak_boat, birch_boat and the rest. One unknown entity type makes the whole selector fail to parse, so the command never ran, while the particles — separate commands — carried on looking correct. The selector now names only three certain types and excludes this pack's own entities with tag=!ra; the decoration exclusions moved into one guard line each, so a future rename costs one guard rather than the entire feature.
• Scorch now works in hover mode. It was gated on an airborne score computed earlier in the player tick; it re-tests the ground itself, so it no longer depends on where it is called from.

Fixed

• The EU Generator's skin vanished. Teaching it to glow wrote the state into the block's NAME — minecraft:furnace[lit=true] — and a block_display's Name is a resource location, which cannot contain brackets. It does not error: the display spawns showing nothing, so the block simply loses its skin. Block states now go through ra_lib:skin/apply_lit, which puts them in Properties where they belong.
• A burning generator reported itself inactive. active was set from how much EU the grid accepted, so a generator with no Battery filled the 50 EU it contributes itself and then read as doing nothing — fuel going down, skin lit, readout saying idle. active now means burning, and a separate line says whether the grid is accepting or full.

• An unlit Industrial Light re-cleared its whole beam every tick, about sixty commands per light per tick for lights that were simply switched off. It now clears on the tick it goes out, with a sweep every ten seconds for beams orphaned by a chunk unload.

• A vertical Liquid Drain ignored everything above it. It returned early unless a player was sneaking next to it, so a barrel of water buckets sitting on top — or buckets dropped on the block — did nothing at all, and the hand was the only way to load a network. It now tries the hand, then a container above, then loose items above. Only the hand path still requires sneaking; the other two run unattended, which is what makes a hopper-fed loading point possible.

• Status billboards rendered inside their own block. The text anchor was the block centre, and the block's top face is only 0.5 above that — so every ladder in the pack, which counts downwards from its first line, put its third line onwards under the top face. Blocks with three or more status lines could only be read by standing inside them. The anchor is now above the block, and a floor in show_literal_line means no ladder can reach back down into it however long it gets.
• EU Generators reported "No fuel" while full of coal. The fuel check tested Items[0], the first occupied stack. A barrel has 27 slots: one stack of anything that is not fuel — a stray cobble, an empty bucket left by a hopper — sits in front of the coal for ever. It now asks the whole container and takes from whichever slot has it. A generator left over from when the block was a real blast furnace now says so instead of silently reading the wrong container, and the goggles name the fuel ("Coal") rather than printing a registry ID.
• The Industrial Light never lit, however much EU was on the grid. It read its own eu_use with a bare data get, and a failed read of a missing path does not error — it stores zero. The light asked the grid for nothing, got nothing back, and read "took 0" as "the grid cannot pay". The amount was never the problem, so no amount of EU could fix it. It now reads through ra_lib:util/property like every other numeric property, and the goggles say which of the two conditions is missing — "No redstone" or "No EU" — instead of a bare "Dark".
• Valves and EU Breakers left one side empty while the other stayed full. They compared raw stored amounts, so a tank farm holding 2000 mL of 300000 looked fuller than a three-pipe stub holding 3000 of 5000, and the bridge called it balanced. They now compare how full each side is, not how much it holds.
• Valves ping-ponged the same litre forever. Moving the whole difference between two sides swaps them rather than levelling them: 3000/2000 became 2000/3000 and back, which is what the steady "Moving: 1000 mL" was. They now move half the gap, which converges.

Changed

• The Creative Fluid Source is a beacon, matching the Creative EU Source. A sponge reads as something that absorbs fluid, which is the opposite of what it does. Both break handlers now clear dropped beacons within one block rather than two, so two creative sources side by side cannot eat each other's drop.

Changed

• Skins take their brightness from the light around them. A block_display samples light at its own position, which is inside the block it draws, where the light is always zero — so every skin needed a brightness override or it rendered pitch black. That override was hardcoded to block:0, right in daylight and wrong beside a torch: the real block would be lit and its skin would not. The level is now sampled one block above, by binary search over fifteen light predicates — four questions rather than fifteen.
• The Thruster only engages at travel speed. A data pack cannot set a player's velocity: the only server-side ways to move a player are teleporting, knockback and vehicles, so a continuous boost has to be a teleport a tick, and that is visible as jitter no matter how well the magnitude is smoothed. What can be fixed is when it fires. It now engages above 0.18 blocks a tick and holds until you drop below 0.10 — two thresholds so a single one at cruising speed cannot flicker. Crossing terrain it works as before; placing blocks it stays out of the way entirely.

Changed

• The Electric Furnace pushes its results to a face you choose — under, front, back or top, cycled with the wrench. The old top-row-in/lower-rows-out slot split stopped it re-smelting its own output but made automation awkward, because a hopper cannot be told which rows to touch. Now any smeltable stack anywhere in the barrel is input and nothing ever comes back in, so there is no slot rule to remember and no way for it to find its own product. It refuses to smelt when the destination is missing or full — checked before any EU is spent or any input consumed, so a blocked output costs and loses nothing. Power mode moved to the goggles tinker: two tools, two settings.
• The furnace skin is a blast furnace, matching the item you place it from, and it now places a light above itself while running — a skin is only a picture and emits no light of its own, unlike the vanilla lit block it imitates.
• The Thruster no longer jitters. It pushed a fraction of last tick's raw movement, and a single tick's delta is noisy — it carries the player's input, collision nudges and the previous push — so every wobble became a different-sized teleport, which is exactly what renders as shaking. The delta now feeds a running average (smoothed = (smoothed * 3 + delta) / 4, about a four-tick time constant) and the push is built from that, so it changes gradually. Below 0.025 blocks a tick it does not teleport at all, which removes the twitching while drifting to a stop.

Changed

• Scorch deals real damage, not only fire. /damage 3 minecraft:on_fire, attributed to the pilot so the kill counts and drops experience, on a ten-tick cadence — at one tick apart it would be twenty hits a second, which deletes anything under a hovering player and makes the burning itself pointless. Burning is still applied every tick.
• Scorch reach is exactly 6 blocks, down from seven.
• Scorch runs only while airborne, gated both at the call site and inside the function.
• No more lava particles in the exhaust — the popping blobs read as dripping stone rather than flame. Flame and small_flame only, with the width coming from a much wider spread instead of from the count, and the plume widening with depth the way thrust actually does.
• The Thruster kit is stronger again — 80% of last tick's travel added back (was 55%), capped at 0.35 blocks a tick each axis (was 0.2), about seven extra blocks a second on top of whatever you were already doing.

Changed

• Scorch's exhaust is far calmer. It was about a hundred particles a tick including explosion billows and large_smoke — a soot cloud rather than a jet, grey swamping the orange and thick enough to hide your own boots. Now flame and small_flame for the shape with a single lava for weight: no smoke, no explosion, nothing grey.

Changed

• The Thruster kit is much stronger — +120% movement speed rather than +45%.
• Scorch's exhaust is a plume, not a pilot light. flame alone reads as a spark however many you ask for; the bulk is lava and large_smoke, and explosion is what makes it puff — one large soft billow does more than hundreds of flame particles.
• Converting to an infinite jetpack says so when it keeps your kits.

Changed

• Jetpack upgrades now live on the chestplate, not on the player. Storing them as player tags meant they followed you onto a different chestplate, survived losing the jetpack entirely, and — the way it actually showed up — made every kit report itself already fitted for ever after the first one. The chestplate is now the record: its custom_data carries the flags, the lore lists them, and the flight code re-derives its tags from the worn item every tick, so a jetpack handed to someone else arrives with its upgrades and taking one off stops you having them. Converting an iron jetpack to infinite keeps the kits fitted to it instead of stripping them.
• The Industrial Light's beam walk no longer depends on constructs I could not verify. The mode travelled as the word "on" in storage and was tested with a root-level compound-filter path, on lines that began with $ while containing no macro placeholder at all — all of it in the one code path that was silently doing nothing. It is now a number in a score compared with matches, and empty space is tested as minecraft:air/minecraft:cave_air by name rather than through the #minecraft:air tag.

Changed

• The EU Generator now walks its own inventory instead of interrogating the fuel registry. Two earlier attempts asked the registry first — "is there coal in there? charcoal?" — sixteen questions per attempt, first against Items[0] and then via execute if items ... container.*. Both tested the container indirectly, and when it kept reporting no fuel with a full stack of coal in it there was no way to tell which half was lying. It now reads Items the way the rest of the pack reads containers, looks each stack's id up in a new id-keyed fuel_map in one step, and takes it out by index. Also cheaper: one lookup per stack present, rather than sixteen tests regardless.
• The Thruster kit no longer applies on the ground. A flight upgrade that makes you walk faster around your base is not a flight upgrade; it now applies only while airborne, and comes off cleanly on landing.
• Fitted jetpack kits are listed on the chestplate, appended to its lore so the tier line survives. (They still live on the player, so swapping chestplates carries the upgrades but not the lore.)
• The Scorch kit shows itself. Flame, lava and falling-lava at the boots plus a visible column down the burn reach, and the reach went from six blocks to seven.

Changed

• The Breeder stops before it starts. It ran thirty-five if items checks against its container every tick — one per animal/food pair — before any of them could match, and paid all thirty-five whenever nothing did, which is nearly always: animals wander off, and the ones present are usually already in love or still on cooldown. One entity-type-tag check now answers "is there an animal here that could breed right now?" and skips the other thirty-five.

• The Unboxer stopped pretending sixteen commands were guarded. Its double-chest handling was sixteen macro lines each reading $execute positioned $(input1) run execute if score ... matches 1 .... Written that way all sixteen still run, still instantiate a macro and still resolve the position, every pass, even for a single chest that can never match. The condition and the positioning moved to one call site.

• EU Generators show when they are running — the furnace skin lights, they emit smoke and flame, and they cast a light level 10 above themselves. The repaint only happens on the tick the state actually changes.

• New debug readouts: /function ra_wires:debug/generator and /function ra_wires:debug/light report, per block, every condition that has to hold for it to work.

v5.1.7 (2026-08-18) — Grids, Bridges, Millilitres

Electric stopped pretending to be a network and became one. Fluids got a unit, a hand-loading point and experience. Two library bugs that had been quietly wrong for a long time are fixed, and the redstone reader was rebuilt.

Added

• Clipboard and Multimeter tools. The Clipboard makes the first block you shift-click the origin and matches every block you shift-click after it, same kind only; shift-click at nothing to clear. Everything is shift+RMB because most configurable blocks are backed by a container and a plain click opens their GUI. The Multimeter reads a block's network in chat: which grid, what it stores, what this block contributes, what it draws or makes.

• Industrial Light — redstone and EU, projects a 10-block beam of minecraft:light. Stops at the first solid block, and clears only light blocks, so nothing a player built can be removed by it.

• Clipboard — click a block to make it the origin, then click others of the same kind to match them to it. Shift-click a block to re-origin, shift-click at nothing to clear. Same-kind only, because half the pack has a property called enabled and a Gas Valve's rate landing on a Randomizer's chance would quietly mean something else. Only data.properties travels; a block's private working state stays put.

• Multimeter — click a block to read its network in chat: which grid, what it stores, what this block contributes, and what it draws or makes.

• Industrial Light — redstone and EU, projects a 10-block beam of minecraft:light. Stops at the first solid block; when it goes out it clears only light blocks, so nothing a player built can be removed by it.

• Electric runs on the transport network engine. Adjacent nodes flood-fill into a grid, the charge belongs to the grid, and a generator's output is spendable by a consumer anywhere on it on the same tick. See the note under Fixed for what it replaced.

• Battery — 10000 EU of grid storage. Wires, switches and breakers now store nothing, so a grid holds what its batteries hold: build them, or spend your generation on the tick it is made.
• EU Breaker, and the Valve repurposed to match: a bridge belongs to neither of the networks it sits between, and while powered by redstone it moves contents from the network behind it into the network in front. It never merges them — a run with a bridge in it is two networks, always.
• Ender Power Vault is a wireless bridge. It joins its local grid, contributes no capacity, and moves EU out of the grid at one end into the grid at the other. Anything the far side cannot take is put straight back.
• Millilitres. A bucket is 5000 mL, a pipe holds 1000, a tank 100000. Network totals moved out of scoreboards and into storage ra:transport nets.n<id>, which is where the per-medium map will go when networks can hold more than one thing at a time.
• Experience and potions are media. One experience point is 100 mL, in both directions.
• A vertical drain is the hand-loading point. Sneak beside it holding a full bucket and its contents go into the network, empty bucket back in hand; with nothing in hand it takes your experience instead, ten points a cycle. Set to place, an experience network gives it back as orbs at the same rate.
• Wrench-configurable throughput: Liquid Drain at 2.5 / 5 / 10 L per second, EU Consumer at 20 / 40 / 80 EU per tick.
• ra_lib:redstone/any, detect_switch, local/{front,back,left,right,up,down} and side — read only what you need, instead of every block paying for a full twelve-direction sweep it then threw away.
• Goggles redraw once a second instead of once every two.

Fixed

• The Liquid Pump could not pump next to water. A pump on two pipes had a 4000 mL network and a water source is 5000 mL, and a source block is all-or-nothing — offering half and deleting the block anyway would quietly destroy a lake. Pumps and drains hold 5000 mL now, one bucket, so they work standing alone. network_too_small is told apart from network_full: one means add a tank, the other means wait.
• Bridges did nothing unless they happened to face along the pipe run. A valve dropped into an east-west line while the player faced south pointed at two empty blocks, with nothing on the block to say so. They have no facing at all now — they look at all six neighbours, find the networks themselves, and move from the fullest to the emptiest.

• A Valve's readout reported the fluid-node fields it does not have and printed N/A for every one of them.

• Bridges have no facing at all now. They look at all six neighbours and find the networks themselves, moving from the fullest to the emptiest. Bridging the block in front and the block behind meant a valve dropped into an east-west pipe run while the player happened to be facing south pointed at two empty spaces and did nothing — with nothing on the block to say so.

• A Valve's readout reported the fluid-node fields it does not have and printed N/A for all of them. It says what it is moving, and why not when it is not.

• The Liquid Pump, Gas Pump and Drain hold 5000 mL — one bucket — so a pump works standing alone. A pump on two pipes had a 4000 mL network and could never accept the 5000 mL source block it was sitting next to, so it refused for ever. network_too_small is now told apart from network_full: one means add a tank, the other means wait.

• One name for one meaning: cooldown. A block that waits N ticks before acting again calls that cooldown, everywhere, and its readout says Cooldown:. The Clock's delay and the Liquid Drain's interval are renamed to it and migrate themselves; the three generators' goggles said Period: over a field called cooldown, which is the kind of drift that makes a setting look like it belongs to something else. delay, extend and pulse on the Delayer, Extender and Shortener stay as they are — those are signal durations, not rate limits, and folding three meanings into one name would be worse than the drift.

• The Block Breaker and Block Placer had no cooldown at all, and the reason was the same shape as the Clock's: five near-identical execute lines re-testing one condition, with the reset on the last. The first line destroys the block in front, so unless block ^ ^ ^1 #air was false by the time the reset re-tested it and the reset never ran — the counter climbed for ever and the gate was open on every tick. The placer emptied itself at a block a tick the same way. Both are one gated call into a fire function now, which resets before it touches the world, and five whole-world selector sweeps per block per tick became one.
• The Data Handler's numeric-type list went back to being one entry beside the registry rather than seven per-block functions. The registry exists so that adding a property means editing one list; the per-block version undid that.

• interval and rate were missing from the registry entirely, so the Handler could not render them — the Liquid Drain's throughput and the bridges' rate were invisible and uneditable. The Industrial Light's eu_use and the bridges' rate are now declared as tuning fields hidden from survival.

• The Clock ignored its setting, because it had two of them. A clock could carry both delay and cooldown: the Data Handler listed both, process read cooldown, and delay — the one a player naturally reaches for — did nothing. The compatibility line meant to merge them only ran when cooldown was absent, which is precisely the case that did not need fixing. The clock now runs on a single property, delay, in ticks, and folds any leftover cooldown into it on every tick. A delay of 1 pulses every tick.

• A number typed into the Data Handler could be stored as a string, and every block then read its LENGTH. data get does not fail on a string — it succeeds and returns the character count. So a Clock set to "5" ran with a period of 1 and one set to "100" ran with a period of 3: the number you typed changed nothing but the number of digits, which is exactly what "it ignores its setting" looks like. Nothing errors and nothing logs. The type detection was never wrong; once a value is a string the editor faithfully keeps it one. ra_lib:util/property now re-parses through a macro — substitution inserts a string's raw characters, so "5" and 5 both parse as an integer — and writes the result back as an int, so the repair happens once and the handler offers a number editor from then on.
• execute store result … run data get <missing path> writes zero, and a period of zero means "fire every tick". Three generators and the EU Consumer read their period that way with no guard, so a block that lost its property did not slow down — it ran flat out. There is now one guarded reader, ra_lib:util/property, with a default and a floor.
• The Liquid Valve, Gas Valve and EU Breaker could not be placed at all. Giving them a facing meant setblock waxed_cut_copper[facing=south], and that block has no states whatsoever — the command failed and nothing appeared. A new dir_type:3 orients the marker and leaves the block plain.

• The Block Placer had no cooldown, so a held signal fired it every tick and emptied a stocked placer in under two seconds. Both it and the Block Breaker now run at one action per second, hidden from the survival Data Handler.

• Electric charge could not travel. Every wire held its own buffer and handed half the difference to one neighbour per tick, which levels charge out rather than delivering it: it crawled a block a tick, a generator with six neighbours fed one of them, and once a run had evened out to within 1 EU the transfer guard stopped it moving at all.

• A reload emptied a network's identity. transport/init overwrote the storage holding each network's medium on every load, while the amount sat in a scoreboard that survived — so a network filled since the last rebuild came back holding contents with no medium, and refused everything its own pumps offered until a drain emptied it.
• Pressure plates did nothing. The redstone reader knew about dust, levers, buttons, redstone blocks, torches, repeaters and comparators, and nothing else. Pressure plates, weighted plates, tripwire hooks, observers, lightning rods and daylight detectors are all read now, from block tags rather than six hand-copied direction tests.
• A torch standing on a block powered it. Vanilla never powers the block a torch is mounted on.
• The Randomizer overwrote the redstone library's output with a dice roll, mid-read, on the same marker. One roll in a hundred came up zero and made it wipe its own output the instant it fired.
• Two adjacent skinned blocks deleted each other's appearance. A skin sat on the block corner while the marker sat at the centre, and from a centre every surrounding corner is the same 0.866 away — no radius could tell them apart. Skins are centre-anchored now, and old ones migrate themselves.
• facing/up and facing/down both claimed left was east, so flipping a block over left its hands unchanged.
• count_inputs was a hand-copied mirror of the redstone reader, with a comment admitting the two had to be kept in step by hand. They share one implementation.

Changed

• The EU Generator is a barrel wearing a furnace skin. A real blast furnace brought two input slots and its own smelting, of which only the fuel slot ever meant anything, so players filled the top with ore and waited. Drop coal in a box is the whole interaction now. Burn times live in a fuels registry beside the other tables; steam still works, so the Boiler chain is intact.
• The Breeder is a barrel wearing a dispenser skin, for the same reason it mattered on the Unboxer: a dispenser throws its own inventory on any rising redstone edge, so a breeder loaded with wheat scattered it across the field the moment you powered it. It reads redstone directly now, since a barrel has no triggered state.
• Tiered pipes and wires are gone. One Copper Pipe, one Wire. The four pipe variants placed the same block with the same marker and the same capacity — gas and liquid pipes were never different, and the tiers stopped meaning anything once a pipe held a litre. Retired place tags still map to the survivors so items already in a chest still place something.
• The Poppy Generator's patch mode is gone. A second code path over the same ground for a block whose whole job is one flower at a time. The Wrench no longer cycles anything on it.

• The survival Data Handler locks fields instead of hiding them: the value is shown with a struck-through red [Modify] and a hover saying why. A censored row made a block look like it had fewer settings than it does. The gamemode test is gone with it — creative players use the Creative Data Handler — and so are redact_next, redact_one and the "N fields hidden" footer. The refusal is enforced server-side too, since a row's action is a /trigger a player can type.

• The EU Generator is a barrel wearing a furnace, not a blast furnace. A real furnace brings its own two input slots and its own smelting, of which only the fuel slot ever meant anything — so players filled the top slot with ore and waited. A barrel is a plain inventory: drop coal in and that is the whole interaction, and ra_lib:skin/apply puts the furnace back on the outside so it still reads as one. It burns solid fuel from its own inventory now, with burn times in a fuels registry beside the other tables. Steam still works, so the water -> Boiler -> steam -> EU chain is intact: fuel is the direct route, steam is the built one.

• The Ender Item Vault's shared mode is gone. Three modes remain — link, send, receive — and a vault still set to shared becomes link, the closest of the three. It took two whole-world entity sweeps a tick to work out which vault a player was standing next to, and it was the one mode that followed people rather than machines, which made it the odd one out in a module about automation.

• Bridges — the Liquid Valve, Gas Valve and EU Breaker — work both ways. They take from whichever side holds more and give to whichever holds less, stopping when the two are level. One-way was a mistake: the placement had a right and a wrong answer that nothing on the block told you about, and a build that looked correct simply did nothing. The facing now picks the axis, not the direction.

• Goggles print units: EU on electric readouts, mL on fluid ones.

• Wire readouts replaced Enabled: on — true of every wire ever placed — with the grid's state and its change per second.
• The Solar Panel's Light: line said "Grid full" when the grid backed up. Split into a grid line and a Sun: line that only ever talks about the sun.
• Wire tiers removed. L2 differed only in a capacity it no longer has and a transfer rate that stopped existing when charge moved onto the grid.

• The EU Switch is placed as waxed_cut_copper, the same block as the Valve.

• The Valve is no longer a shutoff. It is a one-way pump between two networks and needs redstone. Existing builds using one as a closed tap will find it does not conduct until powered, and then only in the direction it faces. To cut a fluid line, remove a pipe. The EU Switch is still a true shutoff.

• ra_lib:redstone/detect no longer computes look-space scores or the twelve direction tags; nothing in the pack read them. detect_local does, for anyone who wants them. The per-source tags are gone.
• Netherite pipes hold the same 1000 mL as copper ones.

Documentation

• Every recipe picture regenerated, and the Recipe Atlas rebuilt — 59 recipes. Two stale pictures for retired tiers removed.
• The Breeder now documents what it breeds: all 22 animals and the food each takes, extracted from the dispatch table so the page cannot drift from the code.
• Item reference, interactive machines, infinite generators, transport networks and ender links updated for everything above.

Known

• Nothing in this release has been tested in game.
• Networks still hold one medium at a time. Filters, and telling one potion from another, wait on that.
• Battery, EU Breaker and Industrial Light have no unlock advancement, and the Clipboard and Multimeter have no recipe — both are given by function for now.

v5.1.6 (2026-08-17) — Recipe Atlas, Data Handler Repairs, Licence

A follow-up to v5.1.5: one page holding every recipe, a Data Handler that no longer mangles what it edits, blocks that decide for themselves what a survival player may retune, and a licence that says what it was always meant to say.

Added

• Recipe Atlas — all 58 recipes on one page, A to Z and by module, with the station each is made at and the give-everything command. Generated from the recipe files, so it cannot drift. It lists the four items that have no recipe too, with the sacrifice and chance that win them on an enchanting table.
• Blocks declare which of their own fields the survival Data Handler hides, so one block's tuning knob is no longer every block's: cooldown is tuning on a generator and the whole point of a Clock. Creative mode shows everything.
• /function ra_ender:debug/vaults reports each vault's mode, channel and reachable partners.

Fixed

• The Data Handler asked for a number when editing any string, and writing one broke what it touched — an ender vault channel written that way stopped matching its partner, so the vault stopped sending. data get succeeds on a string and returns its length, which is what the old type test mistook for a number.
• Properties with no editor were invisible, and hidden ones were still printed in the raw list. Everything a block carries is shown now; only what a block explicitly hides is withheld.
• 23 block types never said they registered, and 13 more said it to everyone rather than to players wearing ra.debug.
• Coal in the offhand did not count as jetpack fuel.
• A Teleport Anchor could not fire on a player's first tick in the world.
• Two enchanting tables a block apart could take each other's result.

Documentation

• The licence is rewritten: addons are explicitly free to build and publish, the snippets in the docs are licensed for that purpose, and the clause that accidentally permitted redistributing the pack "in part and modified" is gone. Adds contributions and Mojang-assets clauses, and a version stamp.
• The home page no longer claims redstone on the Boxer and Unboxer is a lock: both run while powered, and following that warning would have broken working builds.
• The readme covers the four new modules, with corrected counts (52 blocks, 58 recipes).

v5.1.5 (2026-08-17) — Enchant Crafting, Jetpacks, Infinite Generators, Ender Links

Four new gameplay modules, drawn recipe images, a Data Handler that can edit every property it shows, and two electric transport bugs that had been quietly breaking wire runs.

Supported versions: 1.21.9 – 26.2 (data pack formats 88 – 107).

New modules

• Enchant Crafting — sacrifice items on a vanilla enchanting table for a small chance at an upgrade. Extensible through the #ra_enchanting:recipes function tag.
• Jetpacks — Iron and Infinite Iron upgrade kits that fit onto any chestplate. Classic and hover flight, switched with /trigger ra.jp.mode; hover holds station with a servo that reads your vertical speed and aims gravity against it. /trigger ra.jp.power switches the whole thing off, and landing does it for you.
• Infinite Generators — a crafted Generator Casing plus a Core gambled off an enchanting table build the Mineral, Nether and Poppy generators, which regrow their own material in front of themselves.
• Ender Links — vaults that link two places by channel for items, fluids and EU, plus Teleport Anchors with a string id and a table of fifteen targets, one per redstone strength. Item vaults are shared by default: the contents follow whoever walks up, since mirroring one stack into two barrels would give it two extraction points.

Tooling

• Recipe pictures are drawn from vanilla assets by tools/recipe_render instead of being screenshotted, with blocks rendered from their real models. All 58 regenerated.
• The Creative Data Handler builds its rows from a registry and picks the editor from each value's actual type, so properties it used to display but could not change — a wire's transfer_rate, a tank's tier, an anchor's id — are editable, lists included.

Documentation

• The home page warned that redstone on the Boxer and Unboxer had become a lock and told players to remove the signal from existing builds. Both have always shipped running while powered — the inversion was a mid-v5.1.4 workaround, reverted in that same release. Following the warning would have broken working builds.

Fixed

• Electric charge only ever reached the first two blocks of a run: a node handed EU back to the neighbour that had just supplied it, and a transfer latch was never released. Charge now moves downhill only, half the gap at a time.
• A enabled flag written as 1 rather than 1b silently disabled a whole wire run or pipe line. The runtime gates are tolerant now.
• Poppy Generators planted nothing: 26.2 narrowed #minecraft:dirt, which no longer contains grass blocks.
• Block skins rendered black inside the block they cover.
• Eight multiblock library functions had never been committed, because the directory they live in is called build.

v5.1.4 (2026-08-16) — Transport Rewrite, Item Safety, Library Audit

A large maintenance release. The fluid and gas system was rebuilt on a shared network engine, several item-destroying and item-duplicating bugs were fixed, and a full audit pass removed dead code and a class of per-tick performance problems.

Supported versions: 1.21.9 – 26.2 (data pack formats 88 – 107). Most of the content does not need 1.21.9 — see the compatibility table on the home page for what breaks on older versions.

Added

Transport engine - ra_lib:transport — a shared network engine. Adjacent nodes are grouped by flood fill, recomputed only when something is placed or broken and debounced to at most one rebuild every 5 ticks. Per-network totals live in scoreboards; the medium is a string in storage. Fluid and item networks both use it.

Blocks - Boiler — water in one side, steam out the other, over any block in #ra_wires:heat_sources. - Solar Panel — generates EU from sky light, read from the vanilla daylight detector's own power state, so night, rain, roofs and snow cover all work without a custom predicate. - Rock Metallic Drill — rebuilt on the new multiblock API and actually reachable; it was previously registered in no tag and internally broken.

Multiblock authoring - A structure is declared once, facing north, in ra_multiblock:register_types; the library derives the other three facings. - IO helpers ra_lib_multiblock:io/{at,insert,extract,peek,count,is_block} give named access to a multiblock's inputs and outputs, so tick logic never branches on facing. They work for the existing multiblocks too. - Generic validate, check_structure and setup_type hooks; a registered type only needs load and tick entries. - ra_lib_multiblock:try_tier — the wrench asks the registry for a tier instead of naming one hardcoded type, so adding a multiblock never edits the wrench. - ra_lib_multiblock/README.md documents the whole API.

Library - ra_lib:inventory/insert_or_drop — insert what fits, drop the rest. loot insert silently destroys the remainder. - ra_lib:inventory/move_slot — whole-slot transfer via /item replace block … from block …, plus find_free_slot, has_free_slot and container_size. - ra_lib:redstone/count_inputs — counts sides carrying a redstone source, powered or not. - ra:tools/block_name — resolves a block's display name from the block itself. - ra_lib:skin/* — draw one block's appearance over another block's mechanics, for vanilla blocks carrying behaviour that cannot be switched off. Documented under "Block Skins" in the Developer Guide. - Goggles line helpers prop_line, data_line and text_line. - Drain "place" mode, cycled with the goggles tinker: spends network contents putting source blocks back into the world. - Infinite-source rule: nine or more matching sources within two blocks counts as inexhaustible; anything smaller genuinely empties.

Changed

• Fluid contents belong to the network, not to each node. Pipes, tanks and valves do no per-tick work; only pumps, drains and boilers tick.
• Media are strings. medium_id 1/2/5 and the +10 gas offset are replaced by a registry keyed by name holding display name, state, colour, particle, world block and bucket.
• EU Generator burns steam instead of producing power from nothing.
• A closed valve splits its network, so the two halves keep separate contents and separate media.
• Every block owns its goggles readout and its display name, in blocks/<name>/goggles.mcfunction. draw_block is pure routing.
• Electric wires are visually distinct from fluid pipes — a 0.26 core in concrete against the pipes' 0.56 metal. An L1 wire and an L1 pipe were previously the same copper block at the same size.
• Item pipes move whole stacks and cache their filter frame.
• Added type= to 385 entity selectors; the tick graph had 324 untyped ones, each of which walked every loaded entity.
• ra_lib:redstone/detect/dust gates each direction on one connection test: 128 commands per call became 8 when no dust is adjacent.
• UNI Gate writes its 3x3x3 output shell only on a change of result, with a periodic resync.
• RA Wires one-time migrations are version-gated instead of re-running forever; placement is one spec per block instead of sixteen near-identical copies.
• Goggles scanning collects markers in range once and draws each one.
• The Redstone Remote's channel is set through the shared writable-book prompt, which needs no command permissions.

Fixed

Item loss and duplication - A full output container destroyed the overflow in the Unboxer, the Blast Forge and every multiblock IO insert. These now place the stack into an explicitly chosen free slot, dropping it whole when there is none. - Delivered stacks were inserted AND dropped. The first version of insert_or_drop worked out the leftover by subtracting loot insert's return value from the requested count — but that command reports the number of item entries it handled, not the number of items, so a full stack looked almost entirely un-inserted and was duplicated onto the floor. Nothing on that path uses loot insert any more. - The Unboxer duplicated items — it inserted into the output before removing from the box, so any path reaching one and not the other produced both. - The Unboxer only emptied part of a crate. It moved one stored stack per cooldown, so a crate sat half-full in the input between cycles. A crate is now emptied completely in a single activation, and the spent crate is consumed. - The Unboxer threw the crate on the floor. The block was a vanilla dispenser and the Unboxer holds the crates it is unboxing in its own inventory, so any rising redstone edge reaching it fired the contents out. It is now a barrel — same inventory and GUI, no dispense behaviour — wearing a dispenser skin drawn as a block_display, so it still reads as an Unboxer. Note it now opens a barrel's 27 slots rather than a dispenser's 3x3. - Item Crates cannot be placed. The crate's base item is now a command block rendered as a head, rather than a real player head. A crate carries its entire contents in custom_data; placing it as a skull dropped that silently and destroyed everything inside. Command blocks require creative and permission level 2 to place, so a survival player cannot lose a crate that way. - The Boxer ran while unpowered. An earlier attempt at the dispenser problem inverted the redstone control on both storage blocks; the Unboxer was put back but the Boxer was missed. Both run while powered again. - ra_lib:inventory/remove silently failed past slot 8 — every container larger than a dispenser — and reported success anyway. It now handles any container size and amounts split across stacks, all-or-nothing.

Fluid and gas - Pumps did nothing. They probed ^ ^ ^1, local coordinates on a marker whose rotation is always the default, so a pump could only ever see the block to its south. - Pumps fabricated fluid from nothing when no source was found. - Propagation was order-dependent and slow — one block per tick, with the result depending on entity iteration order. - Liquid drain, liquid pump and gas pump had no facing. - Reopening a gas valve gave it the liquid valve's capacity.

Interface - Data Handler [Toggle] did nothing. Both boolean toggles read the property again on the line after writing it, so the pair always undid itself. - Data Handler reported RA Wires blocks as "Unknown Block" while reading their properties correctly. Each handler had its own name table and the two had drifted to 22 and 38 entries. - Item pipe filters never matched. A frame attached to a block sits in the neighbouring block, beyond the 0.75 search radius — and a wider radius cannot tell whose filter it is. Bound by the frame's block_pos now. - The Redstone Remote could not be retuned without cheats; its channel menu suggested a /function command. - The Input Form book vanished when selected. Dropping the book now cancels the request.

Rendering - Z-fighting on every connected pipe and wire pair — both nodes drew a full-length bar over the same volume. Each now draws only its own half. - Connections left dangling next to a destroyed block, because neighbours were refreshed while the dying marker still advertised itself as a node. - Clock and UNI Gate item displays floated half a block above their block; offsets are measured from the block centre, not its floor.

Other - The declared pack format range stopped short of the current game. max_format was 102, which is 26.2-snapshot-3 — an early snapshot, so the range never reached the 26.2 release (format 107) it was aiming at. It now declares min_format 88 through max_format 107, covering 1.21.9 up to 26.2. - ra:predicate/is_sneaking broke at format 102 and now ships in both spellings. That snapshot reworked entity predicates "from a structure with multiple optional fields to one similar to data component maps", which is exactly the shape this predicate used — and it gates the wrench shift-action, the goggles tinker and the Remote's channel prompt, so all three would have gone silent on 26.2. The pre-102 form stays in data/, and a new overlay_102/ supplies the component-map form ("minecraft:flags" instead of "flags"), which the game applies automatically from 26.2-snapshot-3 onward. Overlay entries carry their own min_format/max_format, available since 25w31a — the same version that introduced those fields on the pack itself, so every version this pack loads on understands the overlay. The rest of the pack was audited against the 88 → 107 breaking-change list and touches none of it: no filtered loot function, no contents dynamic loot entry, no renamed game rules, no special crafting recipe types, no removed entity NBT. - Load message reported v5.1.2 while the pack reported v5.1.3. - ra_lib_multiblock:create_marker could set up an unrelated marker anywhere in the world — its selector had no type or distance limit. - UNI Gate AND/NAND treated unpowered repeaters, comparators, torches and buttons as absent inputs. - Goggles drew every billboard twice when two wearers stood near the same block. - ra_lib:placement/place inherited the previous placement's facing when no placer was nearby.

Removed

• ra:crafting — never initialised, never called.
• Dead ra.custom_block.gas_pipe handling; the tag is stripped during migration before any of it could match.
• enabled on liquid pipes, liquid tanks and gas tanks. Nothing read it, so it appeared in the Data Handler as a toggle that changed nothing.
• The Pusher item, which shipped in the Interactive bundle and was recognised by both data handlers but had no placement handler, block folder or tick logic. Placing it did nothing.
• Unused objectives ra.channel, ra.edit_step, ra.inv.slot, ra.mb_enabled.
• Redundant stone-button pass in redstone detection, eight no-op tag sweeps in ra_wires:common/tick_cleanup, and the inert #ra_gates:* / #ra_multiblock:* function tags.

Docs

• README and the wiki home page state the real supported range and carry a compatibility table giving the version floor for each feature — the hard floor is the pack.mcmeta schema, not the content, so most of the pack runs on 1.21.5+ with only Item Pipe filters missing. Both previously advertised "Minecraft 1.21+".
• Block and recipe counts corrected to 45 and 50, counted from source.
• New "Block Skins" section in the Developer Guide covering ra_lib:skin, including what the technique does not hide.

Known issues
