4.3.0 (2025-08-23)
------------------
**API Changes (Backward Incompatible)**
- Reject header names and values containing unpermitted characters `\r`, `\n`, or `\0x00`.
- 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.
