Summary of Changes
This release of cel-go (v0.32.0) introduces significant library expansions alongside a major infrastructure migration. Key highlights include the addition of native support for JWT and HMAC operations, Go-based JSON handling via NativeToValue, and robust timestamp parsing helpers.
Critical Upgrade: This release changes the module and import paths to cel.dev/cel-go. Users must update their import statements when upgrading to this version.
A variety of concurrency and stability fixes are also included, such as addressing nil pointer panics during native object traversals, and fixing cost observability when combined with state tracking or exhaustive eval
