Feb 1, 2025February 2025 — BoundaryML/baml delivered core business-value features and reliability improvements. Branding: published new Boundary logo assets (SVG, PNG, and variants) for consistent usage across the project. Release process: unified version bumping via a Python Typer CLI, updated dependencies, git-status validation, changelog updates, and multi-language bump support. Stability: introduced a merge driver to prevent baml_client conflicts; added a tracing system with types for trace events, batching, uploading, and related RPC modules, plus tests and usage examples. Testing and tooling: migrated Python integration tests from Poetry to uv, updating scripts and docs and removing obsolete workflows. AI integration: Claude requests now support image URLs through AnthropicClient, with tests and dependency updates. Editor/UX: VS Code extension updated to process only .baml files to avoid conflicts, and a CSP revert fixed issues in the VSCode playground webview. Overall impact: faster releases, fewer merge conflicts, improved observability, and expanded AI capabilities.
