python-1.2.2

[1.2.2] - 2026-04-29

Added

• agent-framework-azure-contentunderstanding: New alpha package — Azure AI Content Understanding context provider that auto-analyzes file attachments (documents, images, audio, video) and injects structured results into the LLM context, with multi-document session state, configurable timeout, output filtering via AnalysisSection, and auto-registered list_documents / get_analyzed_document tools (#4829)
