Mekanism: Engineering 1.0.0

This update focuses on compatibility and stability since the public 0.8.0 beta. It adds no new machines.

Compatibility

• Minecraft 1.21.1, Java 21 and NeoForge 21.1.200 or later in the 21.1 series.
• Tested with all five stable Mekanism builds from 10.7.15.81 through 10.7.19.85. Mekanism 10.7.20 and later are outside this build's accepted range.
• Install Mekanism and Mekanism: Engineering on both the client and server. Mekanism Generators, Tools and Additions are optional.

Fixes since 0.8.0

• Quantum Digital Miner: stale location entries are removed when a chunk returns or a stored dimension disappears. Relocation recovery and resource conservation have expanded regression coverage.
• Quantum Energy Receiver: energy delivered from its stored reserve is included in the Receiver's throughput and the Quantum Network Controller's net rate.
• Quantum Portable Teleporter: reconnecting preserves its search attempts and delay. Invalid inverted distance settings are corrected, and the client radar remains within its bounds.
• Server settings: numeric values have safe bounds, including invalid values left by older configurations. Controller state and tick edge cases found during the stability review were corrected.
• Creative tab: the Quantum Chargepad appears once. The Digital Miner Companion and Quantum Portable Teleporter each retain separate empty and charged variants.

Validation and scope

The five Mekanism versions passed local unit, in-world GameTest, dedicated-server and client-screen runs. The release candidate also passed migration checks from the public 0.8.0 build, interrupted-relocation recovery, a two-hour 96-machine workload, 20 complete rebuild cycles, 20 chunk cycles, and English/French screen checks. The final source candidate passed all seven Linux CI jobs, including the four earlier Mekanism versions. Its build and 182 unit tests also passed on the project's local Docker runner.

The owner also checked mining, export and save/reload with the Quantum Digital Miner, the Distributor's 50/50 and 75/25 routing and save/reload, the Petrogenic Synthesis Plant, Quantum Network machines and Curios charging in an isolated ATM10 7.2 copy. Those play checks used the candidate before the creative-tab correction; the corrected JAR has automated coverage. Two authenticated LAN clients and a prolonged integrated ATM10 base workload remain untested.
