• Update the PROTOVALIDATE lint rule to check example field options. Examples will be checked that they satisfy the field constraints, and are only present if constraints are present.
• Update the PROTOVALIDATE lint rule to check predefined rules. Predefined rules will be checked that they compile.
• Add support for a WebAssembly (Wasm) runtime for custom lint and breaking changes plugins. Use the .wasm file extension to specify a path to a Wasm plugin.
