v8.3.0

[v8.3.0] - 2026-07-05

Added

• Added api.test_client(...), a configurable form of api.requests for
  custom base_url values and Starlette TestClient options such as
  raise_server_exceptions=False, without relying on deprecated
  api.session().
• Added v9 compatibility opt-ins: API(json_decimal="string") serializes
  Decimal values as precision-preserving strings, and
  api.graphql(..., partial_data_status=200) returns GraphQL partial-data
  responses with HTTP 200 per the GraphQL-over-HTTP spec. Apps can also pass
  API(implicit_static_fallback=False) to disable bare add_route() static
  fallbacks early, and port_precedence="explicit" to serve() / run() so
  an explicit port= wins over a conflicting PORT environment variable.
• Added head() and options() shortcut decorators on API, RouteGroup,
  and standalone Router instances.

Changed

• Declared the Starlette test-client dependencies explicitly (httpx and
  httpx2), raised the Uvicorn and Granian dependency floors to current
  compatible releases, and allowed Sphinx 9 for documentation builds.
• Removed the PyPy classifier and remaining PyPy-specific test-extra guidance
  now that future CI runs target CPython only.
