+- Keep your musket enchantments and existing oil fuel settings when you upgrade.
+- Let the oil boiler burn Mineralogy crude at the same default rate as basePower crude. Your own fuel settings still take precedence.
+- Keep the fixes for saved drill progress, pump contents, boiler heat and still output.

 - Let Forge fluid sources control their own drainage, preserving the amount and fluid data they return.
 - Keep fluid in the steam pump when an attached tank refuses it, and only charge for successful pickup.

+baseSteam replaces Steam Advantage on 1.12.2 and can read worlds from Steam Advantage or baseSteam on 1.10.2.
