We are pleased to announce the next preview release for the Microsoft PHP Drivers for SQL Server, version 5.7.1-preview. This preview release has been built with PHP 7.2+ and tested on all supported platforms.
Notable items about this release include:
Added
- Support for PHP 7.4
- Support for Red Hat 8 and macOS Catalina (10.15)
- Feature Request #1018 - support for PHP extended string types - Pull Request #1043
- Always Encrypted with secure enclaves, which requires MS ODBC Driver 17.4+ and SQL Server 2019
Removed
- Dropped support for PHP 7.1
Fixed
- Issue #1027 - Fixed how drivers handle query timeout settings
- Pull Request #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+
- Only Windows Certificate Store and Azure Key Vault are supported. Custom Keystores are not yet supported
- Issue #716 - With Always Encrypted enabled, named parameters in subqueries are not supported

Known Issues
- Data Classification metadata retrieval requires ODBC Driver 17.4.2.1+ and SQL Server 2019
- Connection pooling on Linux or macOS is not recommended with unixODBC < 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
