4.20.0

Changed

Helpers - FastAPI Rate Limit

• FastAPI Rate Limit Interceptor Deprecated - FastAPIRestRateLimitHandler, the
  fastapi.rate_limit.identifiers helpers (extract_bearer_token, resolve_jwt_access_token_sub),
  and FastAPIRateLimitConfig are deprecated and will be removed in a future major release.
  Instantiating FastAPIRestRateLimitHandler or calling the identifier helpers now raises
  DeprecationError. FastAPIRateLimitConfig emits a DeprecationWarning on
  instantiation (it cannot raise because BaseConfig instantiates it as a field default at
  import time; the internal default suppresses the warning).
• Replacement - The feature is superseded by the official
  fastapi-redis-sdk (rate_limit() FastAPI
  dependency, X-RateLimit-* / Retry-After headers, distributed per-client counters, Redis 7.4+).
  See the migration guide.
• Unaffected - The gRPC rate-limit interceptor, RateLimitUtils, and RateLimitWindowDTO
  remain supported and are not deprecated.

Tests - FastAPI Rate Limit

• Feature Suite Removed - Removed features/fastapi_rate_limit.feature and
  features/steps/fastapi_rate_limit_steps.py together with the deprecated handler.
