-#############################
-Upgrading from 3.1.2 to 3.1.3
-#############################
-
-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: Remove usage of nice_date() helper (deprecation)
-========================================================
-
-The :doc:`Date Helper <../helpers/date_helper>` function ``nice_date()`` is
-no longer useful since the introduction of PHP's `DateTime classes
-<https://secure.php.net/datetime>`_
-
-You can replace it with the following:
-::
-
-	DateTime::createFromFormat($input_format, $input_date)->format($desired_output_format);
-
-Thus, ``nice_date()`` is now deprecated and scheduled for removal in
-CodeIgniter 3.2+.
-
-.. note:: The function is still available, but you're strongly encouraged
-	to remove its usage sooner rather than later.
-
-Step 3: Remove usage of $config['standardize_newlines']
-=======================================================
-
-The :doc:`Input Library <../libraries/input>` would optionally replace
-occurrences of `\r\n`, `\r`, `\n` in input data with whatever the ``PHP_EOL``
-value is on your system - if you've set ``$config['standardize_newlines']``
-to ``TRUE`` in your *application/config/config.php*.
-
-This functionality is now deprecated and scheduled for removal in
-CodeIgniter 3.2.+.
-
-.. note:: The functionality is still available, but you're strongly
-	encouraged to remove its usage sooner rather than later.
