 ### Known Issues
-- Connection pooling on Linux or macOS not recommended with [unixODBC] < 2.3.6
+- Connection pooling on Linux or macOS 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 diagnostics 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 procedure with XML parameter does not work (Issue [#674](https://github.com/Microsoft/msphpsql/issues/674))
