+  explicitly performed before checking `selected_alpn_protocol()`.

+### Deprecations
+
+- **Eventlet Worker**: The `eventlet` worker is deprecated and will be removed in
+  Gunicorn 26.0. Eventlet itself is [no longer actively maintained](https://eventlet.readthedocs.io/en/latest/asyncio/migration.html).
+  Please migrate to `gevent`, `gthread`, or another supported worker type.
