Global SUComponentDefinitionSetName: Before SketchUp 2022.0.1 (API 10.0) this would not ensure the definition name was unique. As of SketchUp 2022.0.1 the component will be given a unique name automatically if needed.
Global SUEntitiesAddFaces: SUEntitiesAddFaces() will not merge overlapping vertices and edges, which produces SketchUp models with unexpected state. Avoid using these functions and instead use SUGeometryInputRef along with SUEntitiesFill().
Global SUEntitiesSetActiveSectionPlane: Before SketchUp 2023.1 (API 11.1) this function would not accept SU_INVALID as a valid section_plane value and would have returned SU_ERROR_INVALID_INPUT instead
Global SUEntityGetNumAttributeDictionaries: Prior to SDK version 9.1 (SketchUp 2021.1) this function might return a count higher than what SUEntityGetNumAttributeDictionaries() will actually return. For example with faces with a positioned material.
Global SUFaceCreate: SUEntitiesAddFaces() will not merge overlapping vertices and edges, which produces SketchUp models with unexpected state. Avoid using these functions and instead use SUGeometryInputRef along with SUEntitiesFill().
Global SUFaceCreateSimple: SUEntitiesAddFaces() will not merge overlapping vertices and edges, which produces SketchUp models with unexpected state. Avoid using these functions and instead use SUGeometryInputRef along with SUEntitiesFill().
