Fixes an issue in which database striped backups using virtual device interface (VDI) tools might fail to restore with error 3456.6
Fixes an issue in which the full-text auto crawl monitor is aborted when you use full-text search.6
Fixes an issue in which the SQL Server Volume Shadow Copy Service (VSS) Writer can't freeze the database during a VSS-based backup. For more information, see known issue three of SQL Server 2019 CU28.6
Fixes an issue in which Data Analysis Expressions (DAX) queries that use SUMMARIZECOLUMNS and ROLLUPGROUP with multidimensional models might produce incorrect results when running multiple queries that have different sub-selects without clearing the cache, which causes inaccurate totals starting from the second query.6
Fixes a contention issue with high KTM_RECOVERY_MANAGER wait times that you might encounter when running XA distributed transactions. Note: You need to turn on trace flag 8531 as a startup trace flag.6

Limits the extra number of user tokens created by sys.sysprocesses or sys.dm_exec_requests by using trace flag 4673.7.15
Fixes an issue in the lock manager that might cause random access violations and dumps on secondary replicas when the primary replica has 16 or more processors, and the secondary replicas have less than 16 processors.7.15
Fixes an assertion failure (Location: setypes.cpp:1274; Expression: !IsInRowDiff()) that you might encounter at FAILED_ASSERTION_42ac_sqlmin.dll!VersionRecPtr::IsNull when you have multiple nested inserts. Note: You can enable trace flag (TF) 7117 to mitigate the issue. Turn off TF 7117 after the mitigation is done, which means after the version cleaner cleans the problematic page.7.15
