- Define `null` in Pulumi HCL2 - Bind Pulumi HCL2 in topological order s.t. variable types can be properly computed - Fix resources that range over bools and numbers - Add element, length, lookup, readFile, and split functions - Do not rewrite function signatures with input types during binding - Fix splat expression binding for non-lists - Add support for evaluating expressions - Add support for operator precedence to code generators - Add support for constants to the HCL2 IR - Add support for generating ranged resources in Python - Add support for generating conditional resource in Node and Python - Fix various naming issues in Python
