+
+### Limitations
+- No support for inout / output params when using sql_variant type
+- No support for inout / output params when formatting decimal values
+- In Linux and macOS, setlocale() only takes effect if it is invoked before the first connection. Attempting to set the locale after connecting will not work
+- Always Encrypted requires [MS ODBC Driver 17+](https://docs.microsoft.com/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server)
+  - Only Windows Certificate Store and Azure Key Vault are supported. Custom Keystores are not yet supported
+  - Issue [#716](https://github.com/Microsoft/msphpsql/issues/716) - With Always Encrypted enabled, named parameters in subqueries are not supported
+  - Issue [#1050](https://github.com/microsoft/msphpsql/issues/1050) - With Always Encrypted enabled, insertion requires the column list for any tables with identity columns
+  - [Always Encrypted limitations](https://docs.microsoft.com/sql/connect/php/using-always-encrypted-php-drivers#limitations-of-the-php-drivers-when-using-always-encrypted)
+
+### Known Issues
+- Connection pooling on Linux or macOS is not recommended with [unixODBC](http://www.unixodbc.org/) < 2.3.7
+- When pooling is enabled in Linux or macOS
+  - unixODBC <= 2.3.4 (Linux and macOS) might not return proper diagnostic information, such as error messages, warnings and informative messages
+  - due to this unixODBC bug, fetch large data (such as xml, binary) as streams as a workaround. See the examples [here](https://github.com/Microsoft/msphpsql/wiki/Features#pooling)

 The [Microsoft Drivers for PHP for Microsoft SQL Server][phpdoc] are PHP extensions that allow for the reading and writing of SQL Server data from within PHP scripts. The SQLSRV extension provides a procedural interface while the PDO_SQLSRV extension implements PHP Data Objects (PDO) for accessing data in all editions of SQL Server 2012 and later (including Azure SQL DB). These drivers rely on the [Microsoft ODBC Driver for SQL Server][odbcdoc] to handle the low-level communication with SQL Server.
 
-This release contains the SQLSRV and PDO_SQLSRV drivers for PHP 8.0+ with improvements on both drivers and some limitations. Upcoming [releases][releases] will contain additional functionalities, bug fixes, and more.
