## 5.5.0-preview - 2018-12-07
Updated PECL release packages. Here is the list of updates:
### Added
- Added support for PHP 7.3.0
- Added support for Linux Ubuntu 18.10 and mac OS Mojave
- Feature Request [#415](https://github.com/Microsoft/msphpsql/pull/886) - new options at connection and statement levels for both drivers for formatting decimal values in the fetched results
### Fixed
- 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
### 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))
- With ColumnEncryption enabled, fetching varbinary(max), varchar(max) or nvarchar(max) may fail with [ODBC Driver 17.3 CTP](https://blogs.msdn.microsoft.com/sqlnativeclient/2018/09/24/odbc-driver-17-3-preview-for-sql-server-released/)

## Linux 4.0.8 - 2016-12-19
Production release of Linux drivers is available for Ubuntu 15.04, Ubuntu 16.04, and RedHat 7.2. Here is the list of updates:
### Added
- Added `SQLSRV_ATTR_FETCHES_NUMERIC_TYPE` attribute support in PDO_SQLSRV driver.`SQLSRV_ATTR_FETCHES_NUMERIC_TYPE` connection attribute flag handles numeric fetches from columns with numeric Sql types (only bit, integer, smallint, tinyint, float and real). This flag can be turned on by setting its value in `PDO::setAttribute` to `true`, For example,
`$conn->setAttribute(PDO::SQLSRV_ATTR_FETCHES_NUMERIC_TYPE,true);`
If `SQLSRV_ATTR_FETCHES_NUMERIC_TYPE` is set to `true` the results from an integer column will be represented as an `int`, likewise, Sql types float and real will be represented as `float`.
`$conn->setAttribute(PDO::SQLSRV_ATTR_FETCHES_NUMERIC_TYPE,true);`
If `SQLSRV_ATTR_FETCHES_NUMERIC_TYPE` is set to `true` the results from an integer column will be represented as an `int`, likewise, Sql types float and real will be represented as `float`.
Note for exceptions:
- When connection option flag `ATTR_STRINGIFY_FETCHES` is on, even when `SQLSRV_ATTR_FETCHES_NUMERIC_TYPE` is on, the return value will still be string.
- When the returned PDO type in bind column is `PDO_PARAM_INT`, the return value from a integer column will be int even if `SQLSRV_ATTR_FETCHES_NUMERIC_TYPE` is off.
- Added Unicode Column name support([issue #138](https://github.com/Microsoft/msphpsql/issues/138)).

`$conn->setAttribute(PDO::SQLSRV_ATTR_FETCHES_NUMERIC_TYPE,true);`
If `SQLSRV_ATTR_FETCHES_NUMERIC_TYPE` is set to `true` the results from an integer column will be represented as an `int`, likewise, Sql types float and real will be represented as `float`.
`$conn->setAttribute(PDO::SQLSRV_ATTR_FETCHES_NUMERIC_TYPE,true);`
If `SQLSRV_ATTR_FETCHES_NUMERIC_TYPE` is set to `true` the results from an integer column will be represented as an `int`, likewise, Sql types float and real will be represented as `float`.
Note for exceptions:
- When connection option flag `ATTR_STRINGIFY_FETCHES` is on, even when `SQLSRV_ATTR_FETCHES_NUMERIC_TYPE` is on, the return value will still be string.
- When the returned PDO type in bind column is `PDO_PARAM_INT`, the return value from a integer column will be int even if `SQLSRV_ATTR_FETCHES_NUMERIC_TYPE` is off.
- Fixed float truncation when using buffered query.
- Fixed float truncation when using buffered query.
- Fixed handling of Unicode strings and binary when emulate prepare is on in `PDOStatement::bindParam`. To bind a unicode string, `PDO::SQLSRV_ENCODING_UTF8` should be set using `$driverOption`, and to bind a string to column of Sql type binary, `PDO::SQLSRV_ENCODING_BINARY` should be set.
- Fixed string truncation in bind output parameters when the size is not set and the length of initialized variable is less than the output.
- Fixed bind string parameters as bidirectional parameters (`PDO::PARAM_INPUT_OUTPUT `) in PDO_SQLSRV driver. Note for output or bidirectional parameters, `PDOStatement::closeCursor` should be called to get the output value.
