FastAPI 0.131.0 includes Pydantic's Rust-based JSON serialization by default (PR #14962), making ORJSONResponse unnecessary. The new default serialization is 2x faster than the previous approach and eliminates the need for explicit orjson configuration.
Changes:
- Upgrade FastAPI from 0.130.0 to 0.131.0
- Remove orjson dependency (deprecated in 0.131.0)
- Remove ORJSONResponse import and configuration
- Use FastAPI's new default Pydantic-based serialization
