Many SQL Server and Windows Updates were introduced in September and early October, including the latest Cumulative Update for SQL Server 2019, which addresses the snapshot issues introduced by CU7.

Microsoft's official advice to all those who are using the snapshot feature who had installed the update before September 23 2020 was to roll back to CU6 or apply the latest CU (found [here](https://support.microsoft.com/en-gb/help/4577194/cumulative-update-8-for-sql-server-2019)). It was also advised to [drop any database snapshots that were created whilst CU7 was installed.](https://support.microsoft.com/en-gb/help/4570012/cumulative-update-7-for-sql-server-2019)

Notable cyber-security news in the past month includes:
