Pumps & Pistons 1.10.4-beta.1 — Minecraft 26.1.2

Fabric · Java 25 · Beta

• Automobility support now ships inside the complete P&P JAR. Install matching Automobility 1.0.0-beta.1; a separate adapter download is no longer needed.
• Adds the 1,000 L bulk storage tank, attended liquid transfers, safe machine relocation and the ninth illustrated manual chapter.
• Adds the on-demand Trip Computer (K while seated), with saved distance and actual liquid fuel use, driver-confirmed reset and passenger read access.
• Includes gradual can transfers, completion guards and the coordinated progress display for machines and vehicles.
• Preserves existing consumption presets and explicit server fuel choices. New installations use the survival preset; the manual can read the connected server settings.
• Provides optional mechanical and external-heat integration APIs. Compatible Powerworks versions are qualified separately.

Upgrading

Stop normally and back up the world, config and mods. Update the server and clients together. Keep the old adapter configuration or JAR for the first integrated start, check saved machine and vehicle data, then remove the redundant adapter JAR. Older P&P versions still need their matching historical adapter.
