  • Python: [BREAKING] update to v1.0.0 (#5062)
    * updates to final deprecated pieces and versions
    
    * fix mypy
    
    * fix readme links
  • Python: [BREAKING] Redesign Python exception hierarchy (#4082)
    * [BREAKING] Redesign Python exception hierarchy
    
    Replace the flat ServiceException family with domain-scoped branches:
    - AgentException (with InvalidAuth, InvalidRequest, InvalidResponse, ContentFilter)
    - ChatClientException (same consistent suberrors)
    - IntegrationException (same + InitializationError)
    - WorkflowException (Runner, Convergence, Checkpoint, Validation, Action, Declarative)
    - ContentError (AdditionItemMismatch)
    - ToolException / ToolExecutionException (unchanged)
    - MiddlewareException / MiddlewareTermination (unchanged)
    
    Key changes:
    - All Service* exceptions removed (ServiceException, ServiceInitializationError, etc.)
    - AgentExecutionException split into AgentInvalidRequest/ResponseException
    - AgentInvocationError removed, split into AgentInvalidRequest/ResponseException
    - Workflow exceptions moved from _workflows/_exceptions.py into main exceptions.py
    - _workflows/__init__.py emptied; main __init__.py imports directly from submodules
    - Purview exceptions re-parented under IntegrationException hierarchy
    - Init validation errors use built-in ValueError/TypeError instead of custom exceptions
    - CODING_STANDARD.md updated with hierarchy design and rationale
    
    Fixes microsoft/agent-framework#3410

    * Clarify ToolException vs ToolExecutionException docstrings
    
    ToolException: base class for all tool-related exceptions (preconditions,
    connection/init failures).
    ToolExecutionException: runtime call failures (tool call failed, reconnect
    failed, MCP errors).

    * Fix remaining stale imports from agent_framework._workflows
    
    - azurefunctions: _context.py, _app.py, _serialization.py, test_func_utils.py
      used 'from agent_framework._workflows import X' which broke after
      emptying _workflows/__init__.py; changed to direct submodule imports
    - azure-ai-search: test still referenced ServiceInitializationError;
      updated to ValueError to match production code

  • Python: [BREAKING] PR2 — Wire context provider pipeline, remove old types, update all consumers (#3850)
    * PR2: Wire context provider pipeline and update all internal consumers
    
    - Replace AgentThread with AgentSession across all packages
    - Replace ContextProvider with BaseContextProvider across all packages
    - Replace context_provider param with context_providers (Sequence)
    - Replace thread= with session= in run() signatures
    - Replace get_new_thread() with create_session()
    - Add get_session(service_session_id) to agent interface
    - DurableAgentThread -> DurableAgentSession
    - Remove _notify_thread_of_new_messages from WorkflowAgent
    - Wire before_run/after_run context provider pipeline in RawAgent
    - Auto-inject InMemoryHistoryProvider when no providers configured
    
    * fix: update all tests for context provider pipeline, fix lazy-loaders, remove old test files
    
    * refactor: update all sample files for context provider pipeline (AgentThread→AgentSession, ContextProvider→BaseContextProvider)
    
    * fix: update remaining ag-ui references (client docstring, getting_started sample)
    
    * fix: make get_session service_session_id keyword-only to avoid confusion with session_id
    
    * refactor: rename _RunContext.thread_messages to session_messages
    
    * refactor: remove _threads.py, _memory.py, and old provider files; migrate devui to use plain message lists
    
    * rename: remove _new_ prefix from test files
    
    * refactor: rewrite SlidingWindowChatMessageStore as SlidingWindowHistoryProvider(InMemoryHistoryProvider)
    
    * fix: read full history from session state directly instead of reaching into provider internals
    
    * fix: update stale .pyi stubs, sample imports, and README references for new provider types
    
    * fix: remove stale message_store, _notify_thread_of_new_messages, and session_id.key references in samples
    
    * refactor: merge context_providers and sessions sample folders into sessions, remove aggregate_context_provider
    
    * refactor: UserInfoMemory stores state in session.state instead of instance attributes
    
    * feat: add Pydantic BaseModel support to session state serialization
    
    Pydantic models stored in session.state are now automatically serialized
    via model_dump() and restored via model_validate() during to_dict()/from_dict()
    round-trips. Models are auto-registered on first serialization; use
    register_state_type() for cold-start deserialization.
    
    Also export register_state_type as a public API.
    
    * fix mem0
    
    * Update sample README links and descriptions for session terminology
    
    - Replace 'thread' with 'session' in sample descriptions across all READMEs
    - Update file links for renamed samples (mem0_sessions, redis_sessions, etc.)
    - Fix Threads section → Sessions section in main samples/README.md
    - Update tools, middleware, workflows, durabletask, azure_functions READMEs
    - Update architecture diagrams in concepts/tools/README.md
    - Update migration guides (autogen, semantic-kernel)
    
    * Fix broken Redis README link to renamed sample
    
    * Fix Mem0 OSS client search: pass scoping params as direct kwargs
    
    AsyncMemory (OSS) expects user_id/agent_id/run_id as direct kwargs,
    while AsyncMemoryClient (Platform) expects them in a filters dict.
    Adds tests for both client types.
    
    Port of fix from #3844 to new Mem0ContextProvider.
    
    * Fix rebase issues: restore missing _conversation_state.py and checkpoint decode logic
    
    - Add back _conversation_state.py (encode/decode_chat_messages) lost in rebase
    - Fix on_checkpoint_restore to decode cache/conversation with decode_chat_messages
    - Fix on_checkpoint_restore to use decode_checkpoint_value for pending requests
    - Add tests/workflow/__init__.py for relative import support
    - Fix test_agent_executor checkpoint selection (checkpoints[1] not superstep)
    
    * Add STORES_BY_DEFAULT ClassVar to skip redundant InMemoryHistoryProvider injection
    
    Chat clients that store history server-side by default (OpenAI Responses API,
    Azure AI Agent) now declare STORES_BY_DEFAULT = True. The agent checks this
    during auto-injection and skips InMemoryHistoryProvider unless the user
    explicitly sets store=False.
    
    * Fix broken markdown links in azure_ai and redis READMEs
    
    * Fix getting-started samples to use session API instead of removed thread/ContextProvider API
    
    * updates to workflow as agent
    
    * fix group chat import
    
    * Rename Thread→Session throughout, fix service_session_id propagation, remove stale AGUIThread
    
    - Fix: Propagate conversation_id from ChatResponse back to session.service_session_id
      in both streaming and non-streaming paths in _agents.py
    - Rename AgentThreadException → AgentSessionException
    - Remove stale AGUIThread from ag_ui lazy-loader
    - Rename use_service_thread → use_service_session in ag-ui package
    - Rename test functions from *_thread_* to *_session_*
    - Rename sample files from *_thread* to *_session*
    - Update docstrings and comments: thread → session
    - Update _mcp.py kwargs filter: add 'session' alongside 'thread'
    - Fix ContinuationToken docstring example: thread=thread → session=session
    - Fix _clients.py docstring: 'Agent threads' → 'Agent sessions'
    
    * Fix broken markdown links after thread→session file renames
    
    * fix azure ai test
  • Python: Replace Pydantic Settings with TypedDict + load_settings() (#3843)
    * Replace Pydantic Settings with TypedDict + load_settings()
    
    - Remove pydantic-settings dependency, add python-dotenv
    - Delete _pydantic.py (AFBaseSettings, HTTPsUrl)
    - Add _settings.py with generic load_settings() function, SecretString,
      type coercion, and Required field validation (SettingNotFoundError)
    - Convert all 13 settings classes from AFBaseSettings subclasses to
      TypedDict definitions with load_settings() calls
    - Update all consumers from attribute access to dict access
    - Add 20 unit tests for load_settings() covering basic loading, dotenv,
      SecretString, type coercion, and required field validation
    - Update all existing tests for new settings patterns
    
    * Fix mypy type errors from settings conversion
    
    - Fix str | None attribute access in responses_client (walrus operator)
    - Fix SecretString | None narrowing in bedrock (type: ignore after guard)
    - Convert _context_provider.py attribute access to dict access (missed file)
    - Fix endpoint type narrowing in search_provider and context_provider
    - Fix purview: str | None .rstrip(), int | None defaults, urlparse bytes
    
    * Address PR review: required_fields param, type validation, fixes
    
    - Move required field validation from TypedDict annotations (Required)
      to a required_fields parameter on load_settings(), enabling runtime
      decisions about which fields are required
    - Remove Required imports and restore from __future__ import annotations
      in ollama and foundry_local
    - Add _check_override_type() for deterministic ServiceInitializationError
      on invalid override types (e.g. dict passed for str field)
    - Fix all multi-exception test catches back to single exception type
    - Fix Ollama host=None: use .get() so None is passed through to SDK default
    - Fix Purview processor: use explicit is-None checks instead of or operator
    - Remove unused BaseModel import from openai/_shared.py
    - Add 4 new tests (24 total): required_fields param, type validation
    
    * Fix type validation: allow int for float fields
    
    _check_override_type now permits int values for float-typed fields,
    matching Python's standard numeric promotion behavior.
    
    * fix: wrap urlparse arg with str() to fix mypy bytes endswith error
  • Python: [BREAKING] Simplify API: ChatAgent -> Agent, ChatMessage -> Message (#3747)
    * [BREAKING] Rename ChatAgent -> Agent, ChatMessage -> Message, ChatClientProtocol -> SupportsChatGetResponse
    
    Simplify the public API by removing redundant 'Chat' prefix from core types:
    - ChatAgent -> Agent
    - RawChatAgent -> RawAgent
    - ChatMessage -> Message
    - ChatClientProtocol -> SupportsChatGetResponse
    
    Also renamed internal WorkflowMessage (was Message in _runner_context) to avoid collision.
