 ### 0.0.3
 
 Added support for more types including format support for TextElement, StringLiteral, NumberLiteral, and VariableReference. Variable sutstitions can be done by passing a parameters table to `format()`. Internally manipulating nodes in the API is now easier with meta methods. For example merge comments with `Comment + Comment`, attach childred with `Message * Comment`, etc.
