+Starting with Visual Studio Code version 1.93, [the language for SQL files has been renamed](https://code.visualstudio.com/updates/v1_93#_renamed-sql-to-ms-sql) from 'SQL' to 'MS SQL'. As a result, the SQL cell in SAS Notebook is now labeled 'MS SQL'. The SAS Extension for Visual Studio Code does not control the label of the SQL cell in SAS Notebook. The functionality of the SQL cell has not changed, however. Valid PROC SQL code continues to work in the MS SQL cell.
