Release Summary

This release focuses on improving developer tooling and stability. Key highlights include significant enhancements to the REPL (YAML configuration support and parse-only evaluation), the addition of cost estimation for regex operations, and improved test coverage reporting.

On the stability front, this release addresses race conditions in reference types, improves namespace resolution, and ensures formatting directives align strictly with the CEL specification.

Note: This release includes a breaking change regarding how types are handled as variables. Please review the "Breaking Changes" section below.

⚠ Breaking Changes

Remove types as variables: The logic for handling types has been relaxed to support safe rollout of feature packages which introduce new types whose names may collide with existing variables. Please review your policies if you relied on types behaving strictly as variables in previous versions. PR #​1262
