+
+== Overview
+
+WildFly currently provides MicroProfile OpenAPI {OldMicroProfileOpenAPIVersion} support to applications to expose an `/openapi` endpoint that serves an OpenAPI {OldOpenAPIVersion} document of the application's Jakarta RESTful Web Services.
+This feature request upgrades support for this specification to version {NewMicroProfileOpenAPIVersion} as part of version {MicroProfilePlatformVersion} of the MicroProfile platform specification.
+
+Most notably, this release of the https://download.eclipse.org/microprofile/microprofile-open-api-{NewMicroProfileOpenAPIVersion}/microprofile-openapi-spec-{NewMicroProfileOpenAPIVersion}.html[MicroProfile OpenAPI specification] generates OpenAPI documentation conforming to https://github.com/OAI/OpenAPI-Specification/blob/{NewOpenAPIVersion}.0/versions/{NewOpenAPIVersion}.0.md[version {NewOpenAPIVersion} of the OpenAPI specification].
+
+For details, see the https://download.eclipse.org/microprofile/microprofile-open-api-{NewMicroProfileOpenAPIVersion}/microprofile-openapi-spec-{NewMicroProfileOpenAPIVersion}.html#{MicroProfileOpenAPIReleaseNotesAnchor}[Release Notes].
