    💥 Breaking Changes

    👌 Support for namespaced function resolution means that CEL extension functions can now have qualified names, such as base64.encode. This has always been supported by the CEL type-checker and the CEL specification, but was never properly supported by the evaluators. As part of this fix, the type-checker introduces AST rewrites to ensure that all identifiers in the checked AST are fully-qualified. This change simplifies the execution planning phase for the program, but may introduce structural differences between v0.5+ ASTs and those created with prior releases of CEL.

    The structural difference introduced with this change should not affect evaluation. If anything v0.5+ ASTs will improve the conformance of the C++ evaluator with the CEL spec.
