What's wrong

The IMPORTANT note under "Database compatibility level" says:

As of November 2019, in Azure SQL Database, the default compatibility level is 150 for newly created databases.

The ALTER DATABASE compatibility level page gives the current value: "The default compatibility level is 170 for newly created databases in Azure SQL Database and SQL database in Microsoft Fabric" (docs/t-sql/statements/alter-database-transact-sql-compatibility-level.md, "Remarks").

Evidence

Documentation only: the two pages disagree, and the compatibility level page is the reference for this value. Not measured on Azure SQL Database.

Change

The sentence gives 170 and drops the November 2019 date, so it matches the compatibility level page.

…inality estimation page

The note still gave the November 2019 value of 150; the compatibility level page gives 170 for new Azure SQL Database databases.
