- if you are building the driver from source using PHP source, copy the "shared" folder as a subfolder to both the sqlsrv and pdo_sqlsrv folders.
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,
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)).
###Fixed
- Fixed issue with SQLSRV_ATTR_FETCHES_NUMERIC_TYPE when column return type is set on statement ([issue #173](https://github.com/Microsoft/msphpsql/issues/173)).

- Fixed issue with buffered cursor in PDO_SQLSRV driver when CharacterSet is UTF-8 ([issue #192](https://github.com/Microsoft/msphpsql/issues/192)).
- Fixed segmentation fault in error cases when error message is returned with emulate prepare attribute is set to true in PDO_SQLSRV driver.
- Fixed issue with empty output parameters on stored procedure([issue #182](https://github.com/Microsoft/msphpsql/issues/182)).

- Compiler C++ 11 is enabled in config file.
### Fixed
- Fixed the issue with duplicate warning messages in PDO_SQLSRV drivers when error mode is set to PDO::ERRMODE_WARNING.
- Fixed the issue with invalid UTF-8 strings, those are detected before executing any queries and proper error message is returned.
- Fixed segmentation fault in sqlsrv_fetch_object and sqlsrv_fetch_array function.
Windows drivers compiled with PHP 7.0.12 and 7.1 are available. Here is the list of updates:
### Changed
- Drivers versioning has been redesigned as Major#.Minor#.Release#.Build#. Build number is specific to binaries and it doesn't match with the number on the source.
### Fixed
- Fixed the issue with duplicate warning messages in PDO_SQLSRV drivers when error mode is set to PDO::ERRMODE_WARNING.
Linux drivers compiled with PHP 7.0.11 are available for Ubuntu 15.04, Ubuntu 16.04, and RedHat 7.2.
### Fixed
- Fixed segmentation fault when calling PDOStatement::getColumnMeta on RedHat 7.2.
- Fixed segmentation fault when fetch mode is set to ATTR_EMULATE_PREPARES on RedHat 7.2.
- Fixed [issue #139](https://github.com/Microsoft/msphpsql/issues/139) : sqlsrv_fetch_object calls custom class constructor in static context and outputs an error.
Updated Windows drivers (4.1.3) compiled with PHP 7.0.11 and 7.1.0RC3 are available. Here is the list of updates:
### Fixed
- Fixed [issue #139](https://github.com/Microsoft/msphpsql/issues/139) : sqlsrv_fetch_object calls custom class constructor in static context and outputs an error.
Note: These constants should be used in type comparison operations (refer to issue [#87](https://github.com/Microsoft/msphpsql/issues/87) and [#99](https://github.com/Microsoft/msphpsql/issues/99) ), and don't replace the function like constants with similar syntax. For binding parameters you should use the function-like constants, otherwise you'll get an error.
### Fixed
- Fixed undefined symbols at SQL* error when loading the drivers.
- Fixed undefined symbol issues at LocalAlloc and LocalFree on RedHat7.2.
- Fixed [issue #144](https://github.com/Microsoft/msphpsql/issues/144) (floating point exception).
- Fixed [issue #119](https://github.com/Microsoft/msphpsql/issues/119) (modifying class name in sqlsrv_fetch_object).

### Fixed
- Fixed [issue #119](https://github.com/Microsoft/msphpsql/issues/119) (modifying class name in sqlsrv_fetch_object).
-`SQLSRV_ATTR_FETCHES_NUMERIC_TYPE` connection attribute flag is added to PDO_SQLSRV driver to handle 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,
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 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.
- Added support for PDO_SQLSRV driver on RedHat 7.
###Changed
- Improved handling varchar(MAX).
- Improved handling basic stream operations.
## Linux 4.0.0 - 2016-06-11
### Added
- The early technical preview (ETP) for SQLSRV and PDO_SQLSRV drivers for Linux with basic functionalities is now available. The SQLSRV driver has been built and tested on Ubuntu 15.04, Ubuntu 16.04, and RedHat 7.2, and PDO_SQLSRV driver has been built and tested on Ubuntu 15.04, Ubuntu 16.04.
