Change Log
##########
+Version 3.2.0
+=============
+
+Release Date: Not Released
+
+- Core
+
+ - Changed :doc:`URI Library <libraries/uri>` to ignore the ``$config['url_suffix']``, ``$config['permitted_uri_chars']`` configuration settings for CLI requests.
+
+- Libraries
+
+ - Added UNIX socket connection support to :doc:`Session Library <libraries/sessions>` 'redis' driver.
+
+ - :doc:`Cache Library <libraries/caching>` changes include:
+
+ - Added UNIX socket connection support to the 'memcached' driver.
+ - Changed the 'memcached' driver to ignore configurations that don't specify a hostname.
+ - Removed the *socket_type* configuration setting from the 'redis' driver.
+ - Changed data serialization logic in 'redis' driver for better performance.
+
+- 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.
+
+- Helpers
+
+ - Updated :doc:`HTML Helper <helpers/html_helper>` function :php:func:`meta()` with support for "charset" and "property" properties.
+ - Changed :doc:`HTML Helper <helpers/html_helper>` function :php:func:`doctype()` default document type to HTML 5.
+
+Bug fixes for 3.1.0
+-------------------
+
+- Fixed a bug (#4528) - :doc:`Cache Library <libraries/caching>` stored all scalar values as strings with the 'redis' driver.
+

+#############################
+Upgrading from 3.1.x to 3.2.x
+#############################
+
+Before performing an update you should take your site offline by
+replacing the index.php file with a static one.
+
+Step 1: Update your CodeIgniter files
+=====================================
+
+Replace all files and directories in your *system/* directory.
+
+.. note:: If you have any custom developed files in these directories,
+ please make copies of them first.
+
+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 $e)
+ {
+ // Handle the failure
+ }
+
+Or you may leave it to CodeIgniter's default exception handler, which would
+log the error message and display an error screen if you're running in
+development mode.
+
+Remove db_set_charset() calls
+-----------------------------
+
+With the above-mentioned changes, the purpose of the ``db_set_charset()``
+method would now only be to change the connection character set at runtime.
+That doesn't make sense and that's the reason why most database drivers
+don't support it at all.
+Thus, ``db_set_charset()`` is no longer necessary and is removed.
+
+Step 3: Check logic related to URI parsing of CLI requests
+==========================================================
+
+When running a CodeIgniter application from the CLI, the
+:doc:`URI Library <../libraries/uri>` will now ignore the
+``$config['url_suffix']`` and ``$config['permitted_uri_chars']``
+configuration settings.
+
+These two options don't make sense under the command line (which is why
+this change was made) and therefore you shouldn't be affected by this, but
+if you've relied on them for some reason, you'd probably have to make some
+changes to your code.
+
+Step 4: Check Cache Library configurations for Redis, Memcache(d)
+=================================================================
+
+The new improvements for the 'redis' and 'memcached' drivers of the
+:doc:`Cache Library <../libraries/caching>` may require some small
+adjustments to your configuration values ...
+
+Redis
+-----
+
+If you're using the 'redis' driver with a UNIX socket connection, you'll
+have to move the socket path from ``$config['socket']`` to
+``$config['host']`` instead.
+
+The ``$config['socket_type']`` option is also removed, although that won't
+affect your application - it will be ignored and the connection type will
+be determined by the format used for ``$config['host']`` instead.
+
+Memcache(d)
+-----------
+
+The 'memcached' will now ignore configurations that don't specify a ``host``
+value (previously, it just set the host to the default '127.0.0.1').
+
+Therefore, if you've added a configuration that only sets e.g. a ``port``,
+you will now have to explicitly set the ``host`` to '127.0.0.1' as well.
+
+Step 5: Check usage of doctype() HTML helper
+============================================
+
+The :doc:`HTML Helper <../helpers/html_helper>` function
+:php:func:`doctype()` used to default to 'xhtml1-strict' (XHTML 1.0 Strict)
+when no document type was specified. That default value is now changed to
+'html5', which obviously stands for the modern HTML 5 standard.
+
+Nothing should be really broken by this change, but if your application
+relies on the default value, you should double-check it and either
+explicitly set the desired format, or adapt your front-end to use proper
+HTML 5 formatting.
