<ul>
<li>Libraries
<ul>
+ <li>Added a new <a href="libraries/form_validation.html">Form Validation Class</a>. It simplifies setting rules and field names, supports arrays as field names, allows groups of validation rules to be saved in a config file, and adds some helper functions for use in view files. <strong>Please note that the old Validation class is now deprecated</strong>. We will leave it in the library folder for some time so that existing applications that use it will not break, but you are encouraged to migrate to the new version.</li>
<li>Updated the <a href="libraries/sessions.html">Sessions class</a> so that any custom data being saved gets stored to a database rather than the session cookie (assuming you are using a database to store session data), permitting much more data to be saved.</li>
<li>Added the ability to store libraries in subdirectories within either the main "libraries" or the local application "libraries" folder. Please see the <a href="libraries/loader.html">Loader class</a> for more info. </li>
<li>Added the ability to assign library objects to your own variable names when you use <kbd>this->load->library()</kbd>. Please see the <a href="libraries/loader.html">Loader class</a> for more info. </li>
<li>Changed the output of the profiler to use style attribute rather then clear, and added the id "codeigniter_profiler" to the container div</li>
- <li>Added <kbd>is_natural()</kbd> and <kbd>is_natural_no_zero()</kbd> to the <a href="libraries/validation.html">Validation class</a>.</li>
</ul>
</li>
<li>Helpers
<ul>
+ <li>Added several new "setting" functions to the <a href="helpers/form_helper.html">Form helper</a> that allow POST data to be retrieved and set into forms. These are intended to be used on their own, or with the new <a href="libraries/form_validation.html">Form Validation Class</a>.</li>
<li>Added current_url() and uri_segments() to <a href="helpers/url_helper.html">URL helper</a>.</li>
<li>Improved accuracy of calculations in <a href="helpers/number_helper.html">Number helper</a>.</li>
<li>Removed added newlines ("\n") from most form and html helper functions.</li>
