+Version 3.1.8
+=============
+
+Release Date: Mar 22, 2018
+
+- **Security**
+
+ - Updated :doc:`URL Helper <helpers/url_helper>` function :php:func:`auto_link()` to add ``rel="noopener"`` to generated links in order to prevent tab hijacking.
+ - Updated :doc:`Security Library <libraries/security>` method ``xss_clean()`` to also filter JavaScript tag functions.
+ - Fixed a bug where :doc:`Security Library <libraries/security>` method ``xss_clean()`` didn't check for parentheses around JavaScript's ``document``.
+
- General Changes
- Updated :doc:`Email Library <libraries/email>` to always negotiate between TLS 1.0, 1.1, 1.2 when possible (PHP 5.6+) for SMTP connections.
+ - Updated :doc:`Database Library <database/index>` method ``version()`` to exclude suffixes to the main version numbers with the 'postgre' driver.
Bug fixes for 3.1.8
-------------------
- Fixed a bug where :doc:`Form Validation Library <libraries/form_validation>`, :doc:`Email Library <libraries/email>` tried to use ``INTL_IDNA_VARIANT_UTS46`` when it was undeclared.
+- Fixed a bug where :doc:`Query Builder <database/query_builder>` methods ``where()``, ``having()`` treated values passed to them as arbitrary SQL.
+- Fixed a bug (#5423) - :doc:`Database Library <database/index>` method ``insert_id()`` failed due to incorrect server version parsing with the 'postgre' driver.
+- Fixed a bug (#5425) - :doc:`XML-RPC Library <libraries/xmlrpc>` produced an error message related to ``count()`` on PHP 7.2.
+- Fixed a bug (#5434) - :doc:`Image Manipulation Library <libraries/image_lib>` attempted to ``chmod()`` while rendering images with the ``dynamic_output`` option.
+- Fixed a bug (#5435) - :doc:`Database Results <database/results>` method ``field_data()`` hid info about one field if ``limit()`` was previously used with the 'oci8' driver.
