- Added UNIX socket connection support to :doc:`Session Library <libraries/sessions>` 'redis' driver.
+- Database
+
+ - Changed method ``initialize()`` to return void and instead throw a ``RuntimeException`` in case of failure.
+ - Changed method ``db_connect()`` to always set the connection character set (if supported by the driver) and to fail if it can't.
+ - Removed method ``db_set_charset()`` and the ability to change a connection character set at runtime.
Version 3.0.4
=============
Release Date: Not Released
+- General Changes
+
+ - Updated :doc:`Security Library <libraries/security>` method ``get_random_bytes()`` to use PHP7's ``random_bytes()`` function when possible.
+ - Updated :doc:`Encryption Library <libraries/security>` method ``create_key()`` to use PHP7's ``random_bytes()`` function when possible.
+
+Bug fixes for 3.0.4
+-------------------
+
+- Fixed a bug (#4212) - :doc:`Query Builder <database/query_builder>` method ``count_all_results()`` could fail if an ``ORDER BY`` condition is used.
+- Fixed a bug where :doc:`Form Helper <helpers/form_helper>` functions :php:func:`set_checkbox()`, :php:func:`set_radio()` didn't "uncheck" inputs on a submitted form if the default state is "checked".
+- Fixed a bug (#4217) - :doc:`Config Library <libraries/config>` method ``base_url()`` didn't use proper formatting for IPv6 when it falls back to ``$_SERVER['SERVER_ADDR']``.
+- Fixed a bug where :doc:`CAPTCHA Helper <helpers/captcha_helper>` entered an infinite loop while generating a random string.
+- Fixed a bug (#4223) - :doc:`Database <database/method>` method ``simple_query()`` blindly executes queries without checking if the connection was initialized properly.
+- Fixed a bug (#4244) - :doc:`Email Library <libraries/email>` could improperly use "unsafe" US-ASCII characters during Quoted-printable encoding.
+- Fixed a bug (#4245) - :doc:`Database Forge <database/forge>` couldn't properly handle ``SET`` and ``ENUM`` type fields with string values.
+- Fixed a bug (#4283) - :doc:`String Helper <helpers/string_helper>` function :php:func:`alternator()` couldn't be called without arguments.

+Step 2: Change database connection handling
+===========================================
+
+"Loading" a database, whether by using the *config/autoload.php* settings
+or manually via calling ``$this->load->database()`` or the less-known
+``DB()`` function, will now throw a ``RuntimeException`` in case of a
+failure.
+
+In addition, being unable to set the configured character set is now also
+considered a connection failure.
+
+.. note:: This has been the case for most database drivers in the in the
+ past as well (i.e. all but the 'mysql', 'mysqli' and 'postgre'
+ drivers).
+
+What this means is that if you're unable to connect to a database, or
+have an erroneous character set configured, CodeIgniter will no longer
+fail silently, but will throw an exception instead.
+
+You may choose to explicitly catch it (and for that purpose you can't use
+*config/autoload.php* to load the :doc:`Database Class <../database/index>`)
+::
+
+ try
+ {
+ $this->load->database();
+ }
+ catch (RuntimeException $e)
+ {
+ // Handle the failure
+ }
+
+Or you may leave it to CodeIgniter's default exception handler, which would
+log the error message and display an error screen if you're running in
+development mode.
+
+Remove db_set_charset() calls
+-----------------------------
+
+With the above-mentioned changes, the purpose of the ``db_set_charset()``
+method would now only be to change the connection character set at runtime.
+That doesn't make sense and that's the reason why most database drivers
+don't support it at all.
+Thus, ``db_set_charset()`` is no longer necessary and is removed.
