Features

• Add support for injecting HTTPConnection (as Request and WebSocket). Useful for sharing app state in dependencies. PR #1827 by @nsidnev.
• Export WebSocketDisconnect and add example handling WebSocket disconnections to docs. PR #1822 by @rkbeatss.

Breaking Changes

• Require Pydantic > 1.0.0.
  • Remove support for deprecated Pydantic 0.32.2. This improves maintainability and allows new features.
  • In FastAPI and APIRouter:
    • Remove path operation decorators related/deprecated parameter response_model_skip_defaults (use response_model_exclude_unset instead).
    • Change path operation decorators parameter default for response_model_exclude from set() to None (as is in Pydantic).
  • In encoders.jsonable_encoder:
    • Remove deprecated skip_defaults, use instead exclude_unset.
    • Set default of exclude from set() to None (as is in Pydantic).
  • PR #1862.
• In encoders.jsonable_encoder remove parameter sqlalchemy_safe.
  • It was an early hack to allow returning SQLAlchemy models, but it was never documented, and the recommended way is using Pydantic's orm_mode as described in the tutorial: SQL (Relational) Databases.
  • PR #1864.
