+- Added support for Azure AD Access Token (in Linux / macOS this requires [MS ODBC Driver 17+](https://docs.microsoft.com/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server) and [unixODBC](http://www.unixodbc.org/) 2.3.6+)
+- Added support for Authentication with Azure Active Directory using Managed Identity for Azure Resources (requires [MS ODBC Driver 17.3+](https://docs.microsoft.com/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server))

+
+### Removed
+- Dropped support for Ubuntu 17.10
+- Dropped support for PHP 7.0 - [Version 5.3](https://docs.microsoft.com/sql/connect/php/system-requirements-for-the-php-sql-driver?view=sql-server-2017) is the last to support PHP 7.0.
+
+### Fixed
+- Issue [#434](https://github.com/Microsoft/msphpsql/issues/434) - To avoid possible crashes, before freeing stmt in the destructor check if its dbh driver data is NULL
+- Pull Request [#833](https://github.com/Microsoft/msphpsql/pull/833) - Streamlined the error handling to remove a potential cause of crash
+- Pull Request [#836](https://github.com/Microsoft/msphpsql/pull/836) - Modified the config files to enable Spectre Mitigations (use /Qspectre switch) for PHP 7.2 (see related Request [#878](https://github.com/Microsoft/msphpsql/pull/878))
+- Pull Request [#854](https://github.com/Microsoft/msphpsql/pull/854) - Clear Azure Key Vault data after connection attributes are successfully set or when exception is thrown
+- Pull Request [#855](https://github.com/Microsoft/msphpsql/pull/855) - Improved performance by saving meta data before fetching and skipping unnecessary conversions for numeric data
+- Pull Request [#865](https://github.com/Microsoft/msphpsql/pull/865) - Corrected the way SQLPutData and SQLParamData are used when sending stream data to the server
+- Pull Request [#878](https://github.com/Microsoft/msphpsql/pull/878) - Modified the config files to enable Spectre Mitigations for PHP 7.1 (see related Request [#836](https://github.com/Microsoft/msphpsql/pull/836))
+- Pull Request [#891](https://github.com/Microsoft/msphpsql/pull/891) - Improved performance of Unicode conversions
+- Pull Request [#892](https://github.com/Microsoft/msphpsql/pull/892) - Removed warning messages while compiling extensions
+- Pull Request [#904](https://github.com/Microsoft/msphpsql/pull/904) - Enabled compiling extensions statically into PHP
+- Pull Request [#907](https://github.com/Microsoft/msphpsql/pull/907) - Initialized output param buffer when allocating extra space
+- Pull Request [#919](https://github.com/Microsoft/msphpsql/pull/919) - Initialized a boolean variable before passing it by reference into a function that will modify its value
+
+### 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
+  - [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)
+- With ColumnEncryption enabled, calling stored procedures with XML parameters does not work (Issue [#674](https://github.com/Microsoft/msphpsql/issues/674))

 The drivers are distributed as pre-compiled extensions for PHP found on the [releases page](https://github.com/Microsoft/msphpsql/releases). They are available in thread-safe and non thread-safe versions, and in 32-bit and 64-bit versions. The source code for the drivers is also available, and you can compile them as thread safe or non-thread safe versions. The thread safety configuration of your web server will determine which version you need. 
 
-If you choose to build the drivers, you must be able to build PHP 7 without including these extensions. For help building PHP on Windows, see the [official PHP website][phpbuild]. For details on compiling the drivers, see the [documentation](https://github.com/Microsoft/msphpsql/tree/dev/buildscripts#windows) -- an example buildscript is provided, but you can also compile the drivers manually.

 To load the drivers, make sure that the driver is in your PHP extension directory and enable it in your PHP installation's php.ini file by adding `extension=php_sqlsrv.dll` and/or `extension=php_pdo_sqlsrv.dll` to it.  If necessary, specify the extension directory using `extension_dir`, for example: `extension_dir = "C:\PHP\ext"`. Note that the precompiled binaries have different names -- substitute accordingly in php.ini. For more details on loading the drivers, see [Loading the PHP SQL Driver](https://docs.microsoft.com/sql/connect/php/loading-the-php-sql-driver) on Microsoft Docs.
