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.
