Microsoft 365 Agents SDK for Python - Release Notes v0.8.0

Release Date: February 23, 2026
Previous Version: 0.7.0 (Released January 21, 2026)

Major Features & Enhancements

  • Microsoft Copilot Studio (MCS) Connector: Full MCS connector support with OAuth OBO token exchange, new connector_user role type, and copilot_studio channel enum value (#295)
  • Enhanced Multi-Tenant Authentication: Dynamic MSAL client resolution with robust authority and tenant handling for multi-tenant scenarios. Updated MSAL version (#301, #307)
  • Integration Testing Framework Overhaul: Replaced legacy data-driven test infrastructure with a modern scenario-based framework. Introduces Scenario, ClientFactory, and AgentClient abstractions; a fluent assertion API with per-item field-mismatch reporting; a new CLI with env, chat, post, and scenario run commands; and a @pytest.mark.agent_test plugin exposing agent internals as fixtures (#315)

  • SubscribeEvent / SubscribeRequest / SubscribeResponse: Models for real-time event streaming with SSE resumption support (#325)
  • UserAgentHelper: Utility class that automatically injects SDK version and platform information into HTTP User-Agent headers (#325)
  • ConnectionSettings.populate_from_environment(): Static method that loads ConnectionSettings from environment variables (#325)
  • use_experimental_endpoint / enable_diagnostics: New ConnectionSettings flags for experimental endpoint capture and HTTP diagnostic logging (#325)

Bug Fixes
