Red Hat build of Quarkus 1.3.x Integrations
Tested Integrations are a defined set of specifically tested integrating technologies that represent the most common combinations that JBoss Enterprise Middleware customers are using. For these integrations, Red Hat has directly, or through certified partners, exercised our full range of platform tests as part of the product release process. Issues identified as part of this testing process are highlighted in release notes for each Red Hat build of Quarkus release. This list of tested integrations may expand over time.
Red Hat provides both production and development support for the tested integrations in the same major version family at or above the tested version according to your subscription agreement. Earlier versions of a tested integration in the same major version family are supported on a commercially reasonable basis.
