+## 5.7.1-preview - 2019-12-03
+Updated PECL release packages. Here is the list of updates:
+
+### Added
+- Support for PHP 7.4
+- Support for Red Hat 8 and macOS Catalina (10.15)
+- Feature Request [#1018](https://github.com/microsoft/msphpsql/issues/1018) - support for [PHP extended string types](https://github.com/microsoft/msphpsql/wiki/Features#natlTypes) - Pull Request [#1043](https://github.com/microsoft/msphpsql/pull/1043)
+- [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)

 # Linux and macOS Installation Tutorial for the Microsoft Drivers for PHP for SQL Server
-The following instructions assume a clean environment and show how to install PHP 7.x, the Microsoft ODBC driver, Apache, and the Microsoft Drivers for PHP for SQL Server on Ubuntu 16.04, 18.04, and 18.10, RedHat 7, Debian 8 and 9, Suse 12 and 15, and macOS 10.11, 10.12, 10.13, and 10.14. These instructions advise installing the drivers using PECL, but you can also download the prebuilt binaries from the [Microsoft Drivers for PHP for SQL Server](https://github.com/Microsoft/msphpsql/releases) Github project page and install them following the instructions in [Loading the Microsoft Drivers for PHP for SQL Server](https://docs.microsoft.com/sql/connect/php/loading-the-php-sql-driver).
