Mar 1, 2025March 2025: Delivered a more robust, scalable, and secure translation subsystem for NVIDIA/garak. Key features include refactoring and renaming the translation framework to langservice with API updates (target_lang, default model_name, bulk execution indicator, and harness load indicator) which reduces integration friction. Startup performance improved via deferred initialization, minimizing initial workload. Security improvements hardened XSS detection and removed deprecated usages. Documentation and tests were aligned with API changes, improving developer experience and reducing regression risk. Configuration and observability enhancements (default soft_probe_prompt_cap, max_workers migrations, GARAK_LOG_FILE naming, and init-time logging) improve reliability and operability in production. Versioning and data updates were kept current with plugin cache updates, version bumps, and contributor attribution.
