* Keep the Mapping node default type as Point for now, instead of Texture. The latter is a better default, but this is breaking API compatibility and it's too close to release to expect addons to be fixed in time. * Vector Transform and Mapping nodes had properties with name "type" to set the type of vector, but this conflicts with the node type property, so renamed to vector_type now.
