Last month Microsoft released SQL Server 2017 Cumulative Update 4, which is Build 14.0.3022.28.
There are 55 hotfixes in the public fix list. Run the special T-SQL script in the release notes if you are using Query Store and previously ever had SQL Server 2017 CU2 installed (and you were using Query Store on any of your databases at that time). The script will look for any plans that were forced while you were running SQL Server 2017 CU2, and if it finds any, it will unforce those and then clear those from Query Store.
There are several updates both for Columnstore indexes and for Availability Groups.
There will not be any Service Packs for SQL Server 2017, so test and deploy SQL Server 2017 Cumulative Updates as they become available.
SQL Server 2017 and later versions will no longer receive SPs
The Modern Servicing Model (MSM)
Starting from SQL Server 2017:
• SPs will no longer be available. Only Cumulative Updates (CUs) and critical updates (GDRs) will be provided.
• CUs will contain localized content if it’s necessary as what SPs have done.
• CUs will be delivered more frequently at first and then less frequently: every month for the first 12 months, and then every quarter for the final four years of the five-year mainstream lifecycle.
Note The MSM only applies to SQL Server 2017 and later versions.
Earlier versions of SQL Server are not affected by this SP policy change. Service Packs (SPs) will continue to be provided for the reminder of mainstream support for SQL Server 2014 and SQL Server 2016.
