+## 5.3.0 - 2018-07-20
+Updated PECL release packages. Here is the list of updates:
+
+### Added
+- Added support for Azure Key Vault for Always Encrypted functionality. Always Encrypted functionality is supported on Linux and macOS through Azure Key Vault
+- Added support for connection resiliency on Linux and macOS (requires version 17.2 or higher of the [ODBC driver](https://docs.microsoft.com/en-us/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server?view=sql-server-2017))
+- Added support for macOS High Sierra (requires version 17 or higher of the [ODBC driver](https://docs.microsoft.com/en-us/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server?view=sql-server-2017))
+- Added support for Ubuntu 18.04 (requires version 17.2 or higher of the [ODBC driver](https://docs.microsoft.com/en-us/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server?view=sql-server-2017))
+
+### Fixed
+- Issue [#577](https://github.com/Microsoft/msphpsql/issues/577) - Idle Connection Resiliency doesn't work with Column Encryption enabled connections (fixed in MS ODBC Driver 17.1)
+- Issue [#678](https://github.com/Microsoft/msphpsql/issues/678) - Idle Connection Resiliency doesn't work with Connection Pooling (fixed in MS ODBC Driver 17.1)
+- Issue [#699](https://github.com/Microsoft/msphpsql/issues/699) - Binding output parameters fails when the query in the stored procedure returns no data. The test case has been added to the test lab.
+- Issue [#705](https://github.com/Microsoft/msphpsql/issues/705) - Always Encrypted - Retrieving a negative decimal value (edge case) as output parameter causes truncation
+- Issue [#706](https://github.com/Microsoft/msphpsql/issues/706) - Always Encrypted - Cannot insert double with precision and scale (38, 38)
+- Issue [#707](https://github.com/Microsoft/msphpsql/issues/707) - Always Encrypted - Fetching decimals / numerics as output parameters bound to PDO::PARAM_BOOL or PDO::PARAM_INT returns floats, not integers 
+- Issue [#735](https://github.com/Microsoft/msphpsql/issues/735) - Extended the buffer size for PDO::lastInsertId so that data types other than integers can be supported
+- Pull Request [#759](https://github.com/Microsoft/msphpsql/pull/759) - Removed the limitation of binding a binary as inout param as PDO::PARAM_STR with SQLSRV_ENCODING_BINARY
+- Pull Request [#775](https://github.com/Microsoft/msphpsql/pull/775) - Fixed the truncation problem for output params with SQL types specified as SQLSRV_SQLTYPE_DECIMAL or SQLSRV_SQLTYPE_NUMERIC
+
+### Limitations
+- No support for inout / output params when using sql_variant type
+- 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/en-us/sql/connect/odbc/linux-mac/installing-the-microsoft-odbc-driver-for-sql-server?view=sql-server-2017)
+  - 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/en-us/sql/connect/php/using-always-encrypted-php-drivers?view=sql-server-2017#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/) < 2.3.6
+- 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))
+
