Cadwyn

**Yanked** due to a minor breaking change that we fixed in 3.10.1.

Added

* The new approach to internal schemas: instead of having them duplicate certain fields from `latest`, we introduced a new `HEAD` version -- the only one the user maintains by hand. All requests get migrated to `HEAD` and latest schemas are generated from `HEAD`. `cadwyn.structure.HeadVersion` was added to give us the ability to have migrations between `HEAD` and latest, thus eliminating the need for `InternalRepresentationOf` because all the used schemas are now the internal representations

Changed

* `latest` is now named `head` because it no longer represents the newest version. Instead, it is the the `internally used` version and the version that is used for generating all other versions.
* the newest version is not aliased from `latest` anymore. Instead, it is generated like all the rest
* deprecated `InternalRepresentationOf` and the concept of `internal schemas` in favor of `HeadVersion` migrations

Fixed

* A broken link to docs in README.md

Added

* Support for getting openapi.json routes using API version headers instead of path query params

Added

* Discord status badge in README
* Logos to existing status badges in README
* An ability to specify multiple schemas when using `convert_request_to_next_version_for` and `convert_response_to_next_version_for` to be able to migrate multiple types of schemas using the same converter
* Redoc support

Removed

* Dependency from verselect. Now it is included as a part of Cadwyn

Fixed

* `h11._util.LocalProtocolError` when raising `HTTPException(status_code=500)`

Fixed

* Error message for changing path params of an endpoint in an incompatible manner which listed methods instead of path params

Changed

* Deprecated `cadwyn generate-code-for-versioned-packages` and added `cadwyn codegen` instead. It doesn't require `template_package` argument anymore and does not have the `ignore_coverage_for_latest_aliases` argument as we plan to remove this feature in the future. So it only requires `version_bundle`.
