Apr 1, 2025April 2025 (google/xls) delivered five key capabilities that strengthen external integration, reliability, and debugging, while modernizing codegen and build support. The work reduces run-time risk (Z3 upgrades and timeout tuning), improves external usage (public Sanitizer API), and enhances observability (enum streaming) with broader SV support in builds. These changes improve developer productivity, code quality, and trust in automated tooling.
