← 4.14.0 | 4.13.1 → | ↑ 4.x series

Fixed

Interceptors - FastAPI Metric

• Nested Router Path Templates - Resolved metric path template resolution for nested routers in FastAPI 0.137+.
  • Added _flatten_routes() helper to expand _IncludedRouter entries before route matching.
  • Uses iter_route_contexts() for FastAPI >= 0.137.2, falls back to effective_route_contexts() for 0.137.0–0.137.1.

Changed

Configs - ScyllaDB

• Default Replication Strategy - Changed ScyllaDBConfig.REPLICATION_STRATEGY default from SimpleStrategy to NetworkTopologyStrategy with default replication config {"datacenter1": 1}. Update environment files if using SimpleStrategy.

Decorators

• Tracing & Deprecation - Removed redundant wrapper.__wrapped__ = func assignments from capture_transaction, capture_span, async_capture_transaction, async_capture_span, and method_deprecation_warning.

Models - Email DTOs

• Frozen Model Mutation - Use object.__setattr__ in EmailAttachmentDTO to support Pydantic v2 frozen model semantics.
