python-1.20.0

Microsoft has released version 1.20.0 of the Microsoft Agent Framework for Python. This update includes several breaking changes across hosting, declarative workflows, and model integration layers. agent-framework-foundry-hosting was redesigned around request-scoped agent factories, persistent sandbox-isolated sessions, parsed durable Invocations runs, and configurable Responses options. In agent-framework-core , approval and MCP runtime handling were hardened: local approvals now require session backing, fail closed when bindings are unresolved, and apply MCP security labels before dynamically discovered tools become callable. agent-framework-gemini introduces breaking changes to adopt the GOOGLE settings namespace and integrate Gemini Embedding 2. New features include native computer-use support for Responses clients and Foundry embeddings, native vector-store connectors for DuckDB and SQL Server, the TypeSafe AI connector, response-stream gates, and session-scoped file-access isolation. The release also improves dependency resolution for Python 3.15 and msgspec 0.22, while noting redisvl-imposed limits of Python <3.15 on agent-framework-redis .

• Migrate Foundry hosting implementations to use request-scoped agent factories and persistent sandbox-isolated session structures.
• Update declarative workflow definitions to account for aligned workflow state attribute lookups and bounded PowerFx state construction.
• Update Gemini integrations to use the GOOGLE settings namespace and adjust for Gemini Embedding 2 options.
• Review tool approval logic in agent-framework-core to ensure session-backed local approvals exist and fail-closed behaviors do not disrupt valid workflows.
