Kong Enterprise 1.5 is the latest release of the company's enterprise offering, building on the stability and features of Kong Enterprise 1.3. This version introduces significant improvements, including enhancements to OpenID Connect, such as support for client authentication assertions using client_secret_jwt and private_key_jwt methods. A notable new feature is the Application Registration in the Dev Portal and Kong Manager, currently in beta, allowing developers to create applications that integrate backend services and manage API access. The release also includes comprehensive documentation updates, a new getting started guide, and other improvements like encrypted storage of sensitive data, sortable entity lists, IPv6 support, and enhanced plugin functionalities. The company plans to enhance and fully support the Application Registration feature in production environments in future releases based on user feedback from this beta phase.
