SQL Server 2022 Version Numbers

Since its release in November 2022, SQL Server 2022 has undergone a series of updates to enhance performance, security, and reliability. Microsoft has adopted a servicing model that forgoes traditional Service Packs in favor of Cumulative Updates (CUs) and General Distribution Releases (GDRs). This approach ensures that each CU encompasses all previous fixes and improvements, providing a comprehensive update package.

Cumulative Updates (CUs):

CUs are rolled out regularly and include all prior fixes along with new enhancements. As of January 16, 2025, the latest available CU is:

  • CU17: Released on January 16, 2025, this update brings the SQL Server version to 16.0.4175.1. It addresses various issues and introduces performance improvements.

General Distribution Releases (GDRs):

GDRs are primarily security-focused updates, addressing critical vulnerabilities without incorporating the broader fixes found in CUs. The most recent GDRs include:

  • GDR (KB5046861): Released on November 12, 2024, this update addresses specific security vulnerabilities in SQL Server 2022.

Servicing Model Overview:

Microsoft’s current servicing strategy for SQL Server 2022 emphasizes the importance of staying up-to-date:

  • Cumulative Updates (CUs): Released regularly, these updates include all previous fixes and new improvements. Microsoft recommends proactive installation of CUs to ensure systems benefit from the latest enhancements and resolutions.
  • General Distribution Releases (GDRs): Focused on security, GDRs are released as needed to address critical vulnerabilities. They do not include the broader set of fixes found in CUs.

For organizations aiming to maintain optimal performance and security, it’s advisable to adopt the “CU Train,” ensuring all-encompassing updates are applied. However, if an environment requires only essential security patches, the “GDR Train” might be more appropriate. Regularly reviewing and applying these updates is crucial to maintaining a robust and secure SQL Server infrastructure.

Staying informed about these updates and understanding their implications can significantly enhance the performance and security of your SQL Server environment.
