Release v0.10.0 · google/cel-cpp

Release covering updates over the last year including recent refactors for the updated Value type and initial implementation of type checker.

Note: Upcoming changes after this release will migrate many references to protobuf Message types to the canonical versions in CEL spec and will likely require client updates.
