Mekanism: Engineering 0.8.0 — Beta

Second public beta for Minecraft 1.21.1 / NeoForge, and the first public build since 0.5.1: it brings the Quantum Infrastructure (0.6), the Quantum Portable Teleporter, the redesigned Petrogenic Synthesis Plant and the Quantum Chargepad (0.7), and a stabilization pass on the whole mod (0.8). Requires Mekanism 10.7.19 (tested build 10.7.19.85); 10.7.20 and later are not accepted by this build.

New since 0.5.1

Quantum Infrastructure

• Quantum Network Controller — a read-only overview of the Quantum frequencies you can access: every device on a frequency (the device itself, its position and face), measured input and output rates per device, the net rate with a one-minute graph, "Sort by rate" per column, and a click to highlight a device in the world. It never acts on a machine.
• Quantum Energy Receiver (Basic, Advanced, Elite, Ultimate) — draws energy from an existing Quantum Entangloporter frequency and feeds the block it is attached to, like a 4-pixel plate on any face, at the rate of the Energy Cube of its tier (4k, 16k, 64k, 256k J/t). Energy only. Upgrading a Receiver to the next tier keeps its link, faces, redstone mode and pending energy.
• Radioactive Quantum Entangloporter — carries radioactive chemicals across a Quantum frequency, shielded, with no extra reagent. It cannot be broken or moved while its frequency still holds radioactive waste.

Quantum Portable Teleporter

• Three modes: to a Mekanism Teleporter of your frequencies, to checked coordinates in an allowed dimension, or to a random safe place 1,000 to 8,000 blocks away. Every destination is checked (and the landing place shown) before you pay; nothing is taken when a jump is refused.
• Safe landing: solid, harmless ground, head room, no dangerous fluid or lava nearby, inside the world border; a bounded search adjusts the arrival and never builds a platform.
• 1 GJ battery with a Mekanism energy bar and its own charging slot; a jump costs 1% (Teleporter), 25% (random) or 50% (coordinates) of a full battery, free in creative mode like Mekanism's Portable Teleporter. It remembers your last destination. Crafted from a Portable Teleporter, whose energy and frequency are kept.
• Server-side: one operation per player, a short ticket on the arrival chunk only, released on every path.

Petrogenic Synthesis Plant, redesigned

• Now 3 × 3 × 3 instead of 5 × 5 × 4, with a storefront showing its eight products, two block outputs (left and right), water and lava at the back of their reservoirs and energy in between.
• New screen: tank gauges, the rate of every production line, Mekanism energy bar and an energy slot, and a bucket or tank slot above each module bay (the module always comes first).
• Existing plants shrink by themselves to the new shape when their world loads, keeping everything they hold; reconnect their pipes and cables.

Quantum Chargepad

• Charges every energy item of a player standing on it in the same tick: armor, off-hand, hotbar, inventory, and Curios slots through Mekanism's Curios support. 1 GJ stored, 256 MJ/t per player; when energy runs short, worn armor comes first.

Across the mod

• Mekanism energy bars on every screen that shows energy (the blue quantum screens keep their solid green).
• Empty dedicated slots show the item they expect in grey; shift-click always sends an item to its proper slot.
• Speed and Energy Upgrades proven to work on every machine that accepts them.
• Precision Upgrade Controller: the radius is now a server setting, shown with Mekanism's Visuals tab; removed upgrades go to your inventory, and removals are shown in red with a warning before Apply.
• Mekanism's Configurator answers on every visible face of our machines, multiblocks included.
• New Quantum Digital Miner recipe; new Petrogenic Synthesizer model with real water and lava levels behind its glass.

Fixes and stability (0.8)

• Precision Logistical Distributor is now fair over time: a weighted split (for example 75/25) holds whether items arrive one at a time, in small groups or in full stacks. Before, a single item always went to the heaviest output, so a slow input gave 100/0. Each item type keeps its own split, so two items arriving in turn are both shared at the ratio; a full output simply skips its turn and resumes its share when it has room, without a burst to catch up; changing a setting starts the new split at once.
• Frequency displays: window titles are centered on their window; frequency names too long for their space scroll, as in Mekanism, instead of being cut; the Receiver's Public / Trusted / Private buttons are no longer clipped; the frequency text of hosted Mekanism selectors stays inside its frame (Quantum Digital Miner source windows, Radioactive Quantum Entangloporter).
• Quantum Portable Teleporter: checks and random searches are rate-limited on the server (invisible in normal play), a destination Teleporter is never read through an unloaded chunk, the client rejects malformed or oversized server data, and the screen closes if the teleporter in your hand is swapped.
• Texts: the Digital Miner Companion's relocation buttons are in English, the Plant's description gives its real size.
• Tested on this build: unit tests, in-world GameTests, screen tests at every GUI scale in English and French, a dedicated server started, saved and restarted three times across three dimensions, and a world made with 0.5.1 opened by this version.

Installation and scope

Install on both client and server. Minecraft 1.21.1, Java 21, NeoForge 21.1.200 or later in 21.1, Mekanism 1.21.1-10.7.19 (tested 10.7.19.85); Generators, Tools and Additions are optional. Back up your worlds before updating; plants built with 0.5.1 are converted to the new 3 × 3 × 3 shape on load.

Not yet validated in this beta, planned for 1.0.0: several Mekanism versions, long endurance runs, performance measurements at large scale, a real modpack, Curios with the Quantum Chargepad, and multiplayer with two real clients for the 0.6 to 0.8 content (0.5.1 was validated in LAN).
