+**September, 2016** : Updated Windows drivers (4.1.2) compiled with PHP 7.0.10 are available. Here is the list of updates:
+
+- Fixed [issue #119](https://github.com/Microsoft/msphpsql/issues/119) (modifying class name in sqlsrv_fetch_object).
+- Added following integer SQL Types constants for cases which function-like SQL types constants cannot be used e.g. type comparison:
+
+    SQLSRV constant | Typical SQL Server data type | SQL type identifier
+    ------------ | ----------------------- | ----------------------
+   SQLSRV_SQLTYPE_DECIMAL | decimal       | SQL_DECIMAL
+   SQLSRV_SQLTYPE_NUMERIC | numeric       | SQL_NUMERIC
+   SQLSRV_SQLTYPE_CHAR    | char          | SQL_CHAR
+   SQLSRV_SQLTYPE_NCHAR   | nchar         | SQL_WCHAR
+   SQLSRV_SQLTYPE_VARCHAR | varchar       | SQL_VARCHAR
+   SQLSRV_SQLTYPE_NVARCHAR | nvarchar     | SQL_WVARCHAR
+   SQLSRV_SQLTYPE_BINARY   | binary       | SQL_BINARY
+   SQLSRV_SQLTYPE_VARBINARY  | varbinary   | SQL_VARBINARY
+
+    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 the similar syntax, for binding parameters you should use the function-like constants, otherwise you'll get an error.

  - `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,
                `$conn->setAttribute(PDO::SQLSRV_ATTR_FETCHES_NUMERIC_TYPE,true);`

 ## Known Issues
 -  User defined data types and SQL_VARIANT.
+- Passing custom class constructor to sqlsrv_fetch_object reproduce an error([issue#139](https://github.com/Microsoft/msphpsql/issues/139)).
