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.

Why SQL Server Version Numbers Matter for Performance and Security

For organizations aiming to maintain optimal performance and security, it’s advisable to follow the “CU Train” (Cumulative Updates), which ensures that comprehensive updates are applied—directly reflected in your SQL Server version numbers. These updates include performance improvements, bug fixes, and security patches that keep your environment current and reliable.

Choosing the Right Update Path Based on Version Numbers

In environments where only essential security patches are needed, the “GDR Train” (General Distribution Release) may be more appropriate. These updates result in more conservative version number changes and are ideal for systems with strict change control policies. Regardless of which path you choose, regularly reviewing your SQL Server version numbers and applying updates is essential for maintaining a robust and secure infrastructure.
