Cumulative updates (CU)

  • 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 should be installed at the same level of confidence.
  • Microsoft recommends ongoing, proactive installation of CUs as they become available according to these guidelines:
     
    • 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 SQL Server CUs before deploying to production environments.

A number of fixes have been released in this CU and you can check them all here.
