Release 12.1.0

Behavior changes

• PartialType() / DeepPartialType(): documented properties without validators are now stripped or rejected by a whitelisting ValidationPipe.
• swagger-ui-init.js ignores the url query parameter of the docs page. Use swaggerUrl or swaggerOptions.url / urls instead.
• When the setup path ends in a route parameter (e.g. docs/:tenant), the /<last segment>/ aliases for the init script and static assets are no longer registered.
• DocumentBuilder: addGlobalParameters() and addGlobalResponse() apply only to documents created from that builder's config, and build() returns a new copy on every call.
• The demo page (index.html) and the LICENSE file of swagger-ui-dist are never served, and the static assets no longer serve directory index files.
• @ApiHideProperty() hides a property inherited from a parent class, and a property decorated with both @ApiProperty() and @ApiHideProperty() is hidden.
• @ApiIncludeEndpoint(false) counts as not decorated under onlyIncludeDecoratedEndpoints, and controllers without any documented endpoint no longer register their class-level models.
• A default holding a model lists only the properties the model documents.
• Inline OmitType() / PickType() schema names spell only documented keys, and mapped type names are resolved when they are read.
• The CLI plugin metadata of a class that re-declares an inherited property takes precedence over what was inferred for the parent class. Options set with decorators still apply.
• Routes sharing a path and method document the union of their security requirements.
• OpenAPI < 3.1: a webhook sharing its path and method with a route is left out of the document (with a warning) instead of replacing the route.
• Response links to operations that are not in the document are removed.
