## Reporting a Vulnerability
If you discover a security vulnerability, we ask that you **do not** create an issue on GitHub. Instead, please [send a message to the core-devs](https://community.sanicframework.org/g/core-devs) on the community forums. Once logged in, you can send a message to the core-devs by clicking the message button.
Alternatively, you can send a private message to Adam Hopkins on Discord. Find him on the [Sanic discord server](https://discord.gg/FARQzAEMAA).
This will help to not publicize the issue until the team can address it and resolve it.

## Version 22.3.0
### Features
- [#2347](https://github.com/sanic-org/sanic/pull/2347) API for multi-application server
- 🚨 *BREAKING CHANGE*: The old `sanic.worker.GunicornWorker` has been **removed**. To run Sanic with `gunicorn`, you should use it thru `uvicorn` [as described in their docs](https://www.uvicorn.org/#running-with-gunicorn).
- 🧁 *SIDE EFFECT*: Named background tasks are now supported, even in Python 3.7
- [#2357](https://github.com/sanic-org/sanic/pull/2357) Parse `Authorization` header as `Request.credentials`
- [#2361](https://github.com/sanic-org/sanic/pull/2361) Add config option to skip `Touchup` step in application startup
- [#2372](https://github.com/sanic-org/sanic/pull/2372) Updates to CLI help messaging
- [#2382](https://github.com/sanic-org/sanic/pull/2382) Downgrade warnings to backwater debug messages
- [#2396](https://github.com/sanic-org/sanic/pull/2396) Allow for `multidict` v0.6
- [#2401](https://github.com/sanic-org/sanic/pull/2401) Upgrade CLI catching for alternative application run types
- [#2402](https://github.com/sanic-org/sanic/pull/2402) Conditionally inject CLI arguments into factory
- [#2413](https://github.com/sanic-org/sanic/pull/2413) Add new start and stop event listeners to reloader process
- [#2414](https://github.com/sanic-org/sanic/pull/2414) Remove loop as required listener arg
- [#2415](https://github.com/sanic-org/sanic/pull/2415) Better exception for bad URL parsing
- [sanic-routing#47](https://github.com/sanic-org/sanic-routing/pull/47) Add a new extention parameter type: `<file:ext>`, `<file:ext=jpg>`, `<file:ext=jpg|png|gif|svg>`, `<file=int:ext>`, `<file=int:ext=jpg|png|gif|svg>`, `<file=float:ext=tar.gz>`
- 👶 *BETA FEATURE*: This feature will not work with `path` type matching, and is being released as a beta feature only.
- [sanic-routing#57](https://github.com/sanic-org/sanic-routing/pull/57) Change `register_pattern` to accept a `str` or `Pattern`
- [sanic-routing#58](https://github.com/sanic-org/sanic-routing/pull/58) Default matching on non-empty strings only, and new `strorempty` pattern type
- 🚨 *BREAKING CHANGE*: Previously a route with a dynamic string parameter (`/<foo>` or `/<foo:str>`) would match on any string, including empty strings. It will now **only** match a non-empty string. To retain the old behavior, you should use the new parameter type: `/<foo:strorempty>`.
### Bugfixes
- [#2373](https://github.com/sanic-org/sanic/pull/2373) Remove `error_logger` on websockets
- [#2381](https://github.com/sanic-org/sanic/pull/2381) Fix newly assigned `None` in task registry
- [sanic-routing#52](https://github.com/sanic-org/sanic-routing/pull/52) Add type casting to regex route matching
- [sanic-routing#60](https://github.com/sanic-org/sanic-routing/pull/60) Add requirements check on regex routes (this resolves, for example, multiple static directories with differing `host` values)
### Deprecations and Removals
- [#2362](https://github.com/sanic-org/sanic/pull/2362) 22.3 Deprecations and changes
1. `debug=True` and `--debug` do _NOT_ automatically run `auto_reload`
2. Default error render is with plain text (browsers still get HTML by default because `auto` looks at headers)
3. `config` is required for `ErrorHandler.finalize`
4. `ErrorHandler.lookup` requires two positional args
5. Unused websocket protocol args removed
- [#2344](https://github.com/sanic-org/sanic/pull/2344) Deprecate loading of lowercase environment variables
### Developer infrastructure
- [#2363](https://github.com/sanic-org/sanic/pull/2363) Revert code coverage back to Codecov
- [#2405](https://github.com/sanic-org/sanic/pull/2405) Upgrade tests for `sanic-routing` changes
- [sanic-testing#35](https://github.com/sanic-org/sanic-testing/pull/35) Allow for httpx v0.22
### Improved Documentation
- [#2350](https://github.com/sanic-org/sanic/pull/2350) Fix link in README for ASGI
- [#2398](https://github.com/sanic-org/sanic/pull/2398) Document middleware on_request and on_response
- [#2409](https://github.com/sanic-org/sanic/pull/2409) Add missing documentation for `Request.respond`
### Miscellaneous
- [#2376](https://github.com/sanic-org/sanic/pull/2376) Fix typing for `ListenerMixin.listener`
- [#2383](https://github.com/sanic-org/sanic/pull/2383) Clear deprecation warning in `asyncio.wait`
- [#2387](https://github.com/sanic-org/sanic/pull/2387) Cleanup `__slots__` implementations
- [#2390](https://github.com/sanic-org/sanic/pull/2390) Clear deprecation warning in `asyncio.get_event_loop`

### Features
- [#2378](https://github.com/sanic-org/sanic/pull/2378) Introduce HTTP/3 and autogeneration of TLS certificates in `DEBUG` mode
