January 2024 (version 23.1.0-beta0001) aka Hornussen release

Codenamed as Hornussen Sport Read the Docs: Ocelot 23.1

Focus On

Multiplexing middleware aka Request Aggregation feature

- Significant refactoring and design review of the [Multiplexer](https://github.com/ThreeMammals/Ocelot/tree/develop/src/Ocelot/Multiplexer) - Optimizing multiplexer performance: `HttpContext` is not copied when there is only one downstream route, and etc. - Fixed [the bug](https://github.com/ThreeMammals/Ocelot/pull/1462) in the multiplexer: `HttpContext.User` information was not copied if there was more than one downstream request.

System routing. Content streaming when Transfer-Encoding: 'chunked'

- Correction of [the bug](https://github.com/ThreeMammals/Ocelot/pull/1972) when creating requests: The header [Transfer-Encoding](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Transfer-Encoding): `chunked` was present even when there was no content or the request body size was 0. These cases are now addressed.

Updates of the features: QoS, Load Balancer and Error Status Codes

- [Quality of Service](https://ocelot.readthedocs.io/en/latest/features/qualityofservice.html): Possibility of implementation of custom Polly v8.2 providers. New `AddPolly` extension methods. - [Load Balancer](https://ocelot.readthedocs.io/en/latest/features/loadbalancer.html): Extension of the route key format, ensuring that the key remains unique for cases of **UpstreamHost** route property and **ServiceName** vs **ServiceNamespace** properties in Consul setup. - [Error Status Codes](https://ocelot.readthedocs.io/en/latest/features/errorcodes.html): When [413 Content Too Large](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/413), Ocelot now returns a 413 `PayloadTooLargeError` (Ocelot error code `41`).
