JEP 527, Post-Quantum Hybrid Key Exchange for TLS 1.3, has been elevated from Proposed to Target to Targeted for JDK 27. This JEP proposes to enhance the implementation of RFC 8446, Transport Layer Security (TLS) Protocol Version 1.3, using the Hybrid Key Exchange in TLS 1.3 specification, currently being drafted by the Internet Engineering Task Force (IETF) in conjunction with JEP 496, Quantum-Resistant Module-Lattice-Based Key Encapsulation Mechanism, delivered in JDK 24.
RC0 introduces a number of notable new features, including official support for Ubuntu 24.04 in development and testing scenarios and the default enablement of TLS 1.3. Support for Ubuntu 24.04 is currently limited to the Enterprise Evaluation Edition, which is available for 180 days. For production, Microsoft currently recommends SQL Server 2022 in combination with Ubuntu 22.04 or RHEL 9. This gives organizations the opportunity to experiment with the latest Linux distribution and prepare for a later production-ready release.
