+basePower 2.4.16.2601021 (Minecraft 26.1.2)
+
+- Require OreSpawn 4.1.1 so old generation rules keep their saved settings without enabling duplicate modern ore rules.
+- Bring basePower to Forge 64 and Java 25 without renaming machines, items or saved data.
+- Use the new screen extraction API and native sprite clipping for fluid gauges.
+- Keep oil models tied to the current animated atlas, including after resource reloads.
+- Register only our own block textures in the atlas, so another mod's small entity textures cannot break client startup.
+- Use Minecraft's native container lock check and keep conveyors out of either locked half of a double chest.
+- Keep the returned container when the fuel helper consumes the last item in a stack.
+- Keep the saved enchantments on old dropped items and chest-minecart contents when Base Metals upgrades the world first.
+- Update old OreSpawn output block names without replacing saved generation settings. Keep backups and reports, and stop for review rather than guess when saved rules conflict.
+- Finish imported generation settings before opening the first world, including the old vanilla quartz name.
+- Move the existing farmer and toolsmith trades to Minecraft's native trade data and tags, keeping their prices and quantities.
+- Prepare selected, locked worlds before Minecraft relocates old world and player files. Keep world previews and fallback files read-only.
+- Keep the shared Base Metals migration hook and add new test evidence for this target. Machine, upgrade, restart, graphical and two-world endurance checks pass, and manual testing is accepted.
