pdo_sqlsrv: Changelog

Version Message
5.12.0 Added
- Support for PHP 8.3
- Support for Alpine 3.19

Removed
- Support for PHP 8.0
- Support for Ubuntu 18.04
- Support for Alpine 3.15

Fixed
- Update connection string keywords set function (#1484)
- Fix error throw for multiple result sets (#1485)
- Fix invalid precision error (#1497)

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
- This release requires ODBC Driver 17.4.2 or above. Otherwise, a warning about failing to set an attribute may be suppressed when using an older ODBC driver.
- 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)

[Limitation]
- Limited support for inout / output params when using sql_variant type
[Known Issues]
- When pooling is enabled in Linux or MAC
- unixODBC 2.3.4 or prior (Linux and MAC) might not return proper diagnostics 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 (https://github.com/Microsoft/msphpsql/wiki/Connection-Pooling-on-Linux-and-Mac)
