Bumps h2 from 4.1.0 to 4.3.0.

Changelog

Sourced from h2's changelog.

4.3.0 (2025-08-23)

API Changes (Backward Incompatible)

  • Reject header names and values containing illegal characters, based on RFC 9113, section 8.2.1. The main Python API is compatible, but some previously valid requests/response headers might now be blocked. Use the validate_inbound_headers config option if needed. Thanks to Sebastiano Sartor (sebsrt) for the report.

API Changes (Backward Compatible)

  • h2 events now have tighter type bounds, e.g. stream_id is guaranteed to not be None for most events now. This simplifies downstream type checking.
  • Various typing-related improvements.

Bugfixes

  • Fix error value when opening a new stream on too many open streams.

4.2.0 (2025-02-01)

API Changes (Backward Incompatible)

  • Support for Python 3.6 has been removed.
  • Support for Python 3.7 has been removed.
  • Support for Python 3.8 has been removed.
  • Remove mistakenly set max_inbound_frame_size attribute on H2Stream.

API Changes (Backward Compatible)

  • Support for Python 3.11 has been added.
  • Support for Python 3.12 has been added.
  • Support for Python 3.13 has been added.
  • Add an ability to send outbound cookies separately to improve headers compression.
  • Updated packaging and testing infrastructure.

Bugfixes

  • Fix repr() checks for Python 3.11
  • Fix asyncio / wsgi examples.
  • Clarify docs on using curl with http2.
