[Release] langchain-ai/langchain langchain-model-profiles==0.0.6: langchain-model-profiles==0.0.6

langchain-model-profiles version 0.0.6 is a maintenance and feature release that includes validation of tool call chunks during streaming, dependency updates across multiple packages (langsmith, urllib3, langchain-core), security patches (pygments CVE-2026-4539), and infrastructure improvements. The release encompasses 80+ commits with focus on stability, testing enhancements, and schema validation for model profiles. Key additions include new model profile fields (text_inputs, text_outputs), improved streaming support with content-block-centric v2, and various bug fixes across partner integrations.

Key Points

• •Validate tool call chunks during streaming to ensure data integrity in streaming workflows
• •Add new model profile fields (text_inputs, text_outputs) for better capability description
• •Implement content-block-centric streaming (v2) for improved streaming architecture
• •Update critical dependencies: langsmith (0.7.31→0.8.0), urllib3 (2.6.3→2.7.0), langchain-core (1.3.2→1.3.3)
• •Apply security patch for pygments CVE-2026-4539 across all packages (>=2.20.0)
• •Sort generated profiles by model ID for stable, reproducible diffs in version control
• •Add missing ModelProfile fields and implement schema drift warnings to catch inconsistencies
• •Enhance CI/CD with lockfile validation checks and Dependabot version-bound preservation
• •Support new OpenRouter provider package (langchain-openrouter) integration
• •Improve testing infrastructure with pytest upgrades (9.0.2→9.0.3) and streaming output suppression in CI
