- Added a multi-state checkbox
- Minor tweaks and fixes to NumberBox, ComboBox and TextInputSingle
- Cleanup of TreeBox, ListBox code. Some work on PropertiesBox.
- Renamed ‘lib/depot.lua’ to ‘ui_load.lua’. Depot was a resource loading library which I don’t believe I ever released formally.
- Cleaned up shared assertion functions, and updated PILE Base to 1.1.4.
