webtransport

# Changelog

## 0.2.2

- Docs: README gains a Sponsors section (Enki Multimedia logo vendored under `docs/images/`).
- Docs: fix invalid `webtransport:open_stream(Session, bidi | uni)` snippet — type-union pipe was in expression position; now `bidi  %% or uni`.
- CT: cover `listeners/0`, `listener_info/1`, and `start_listener/2` cert/key error paths (`webtransport.erl` line coverage 51% → 54%).

## 0.2.1

- `start_listener/2` (h3): switch the listener loop from `spawn_link/3` to `spawn/3` so `stop_listener/1` no longer propagates a `shutdown` exit to the caller. The interactive shell (and any non-trapping caller) now stays clean across a full lifecycle.
- `webtransport_session:init/1`: distinguish a handler module that fails to load (`{handler_not_loaded, M, Reason}`) from a loaded module missing `init/2` or `init/3`.
- README: quick-start now launches the shell with `ERL_FLAGS="-pa examples" rebar3 shell --apps webtransport` so handler modules outside `src/` are reachable.
- Regression test: `stop_listener_does_not_kill_caller_test` (h3 + h2 groups).

Known issue (tracked upstream in `quic`): a graceful `close_session/1` still emits a `quic_h3_connection` `quic_closed` CRASH REPORT because the dep treats any QUIC-conn `'DOWN'` as abnormal. Will resolve when `quic` is bumped.

## 0.2.0

- Switch `h2` and `quic` deps to hex packages: `h2 0.5.0`, `quic 1.3.0`.
- Add `public_key` to the application list.
- Clean dialyzer run: dropped dead `{error, _}` clauses around `h2_capsule:decode/1` and `h2_varint:decode/1`, removed unreachable `Router =:= undefined` branch, dropped unsupported `h3_datagram_enabled` from `quic_h3:start_server/3` opts, switched listener loop to `spawn_link/3` for static reachability.
- Configure `xref_checks` (skip `exports_not_used` for the public API) and `dialyzer` (`plt_extra_apps: [public_key, ssl, crypto, inets]`).
- Add GitHub Actions CI: OTP 26/27 matrix runs compile, xref, eunit, dialyzer; separate job builds ex_doc.

## 0.1.0

- Initial release.
