Cumulative updates (CU) are now available at the Microsoft Download Center for Windows.
Only the most recent CU that was released for SQL Server 2017 is available at the Download Center.
CU packages for Linux are available at https://packages.microsoft.com/.
- Each new CU contains all the fixes that were included with the previous CU for the installed version of SQL Server.
- SQL Server CUs are certified to the same levels as Service Packs, and they should be installed at the same level of confidence.
- Microsoft recommends ongoing, proactive installation of CUs as they become available:
- Historical data shows that a significant number of support cases involve an issue that has already been addressed in a released CU.
- CUs may contain added value over and above hotfixes. This includes supportability, manageability, and reliability updates.
- We recommend that you test CUs before you deploy them to production environments.
