0.3.1
- Fixed compilation by explicitly reimplementing IMod.RegisterDependencies; DataOnlyMod seals its interface implementation in CoI 0.8.6.
- Added -30 s, -10 s, -1 s, +1 s, +10 s, and +30 s cycle-duration controls to the Inspector.
- Fixed the placement-height restriction not being enforced in 0.3.0.
- Added a public-API entity addition validator for Metered Gate placement.
- The validator calculates height relative to rounded terrain height and enforces the Flat Connector PlacementHeightRange.
- Out-of-range normal placement, Shift movement, cloning, blueprints, and moves are now rejected.
- Still uses no Harmony patches and no bundled third-party runtime.

- Added continuous 20 kW power consumption and native power priority.
- Added v1-to-v2 save migration for 0.1.0/0.2.0 buildings.

0.2.0

0.1.0
