July 2026 monthly summary for BoundaryML/baml: - Consolidated multi-language packaging and runtime namespaces by renaming the core runtime/SDK namespace from baml_core to baml_bridge across Python, Node, Go, and WASM, aligning generated bindings, test fixtures, and release artifacts. Updated CI/CD templates and proto definitions to reflect the new bridge namespace, delivering a coherent and maintainable artifact surface (baml-bridge/pypi, npm packages, and bridge proto paths). - Implemented CI/build system improvements and artifact gating to strengthen CI reliability and product quality. Introduced sticky PR comments for size gates, clearer per-platform artifact reporting, and improved fork handling for previews; updated baseline measurements across all platforms. - Advanced platform, language, and cross-runtime capability with a major refactor: consolidating Node bridge and TypeScript generator under a shared SDK foundation, and enabling Web/Workers outputs with an enhanced test harness for runtime-aware testing (vitest_node, vitest_web, vitest_workers). This positions BoundaryML/baml for multi-runtime delivery while preserving existing Node behavior. - Enhanced BAML CLI usability and developer experience: clearer error messaging, OS-specific installation guidance, a rename of --path to --dir, and added automated tests to ensure command reliability and install flows. - Strengthened provider integration and reliability: expanded Google Vertex AI provider support with explicit project/location handling, improved credential precedence and error messaging, and added end-to-end tests to validate provider routing and quota handling.
