- [Always Encrypted with secure enclaves](https://github.com/microsoft/msphpsql/wiki/Features#alwaysencryptedV2), which requires [MS ODBC Driver 17.4+](https://docs.microsoft.com/sql/connect/odbc/download-odbc-driver-for-sql-server?view=sql-server-ver15) and [SQL Server 2019](https://www.microsoft.com/sql-server/sql-server-2019)
[Removed]
- Dropped support for [PHP 7.1](https://www.php.net/supported-versions.php)
[Fixed]
- Issue [#1027](https://github.com/microsoft/msphpsql/issues/1027) - Fixed how drivers handle query timeout settings
- Pull Request [#1049](https://github.com/microsoft/msphpsql/pull/1049) - performance improvement for fetching from tables with many columns - cached the derived php types with column metadata to streamline data retrieval
[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]
- Data Classification metadata retrieval requires ODBC Driver 17.4.2.1+ and [SQL Server 2019](https://www.microsoft.com/sql-server/sql-server-2019)
- 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) |
