<h2><a class="toc-backref" href="#id2">Enhancements</a><a class="headerlink" href="#enhancements" title="Permalink to this headline"></a></h2>
<ul class="simple">
<li><p>The location for the SQLite3 database has changed and by default will be now located in a <code class="docutils literal notranslate"><span class="pre">writable</span></code> folder instead of the <code class="docutils literal notranslate"><span class="pre">public</span></code> folder.</p></li>
<li><p>New CLI command: <code class="docutils literal notranslate"><span class="pre">cache:clear</span></code> that will destroy all data within the current cache engine.</p></li>
<li><p>Thanks to samsonasik, we have several libraries brought up to 100% test coverage.</p></li>
<li><p>A few small performance increases. Every ounce matters!</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">getFieldData()</span></code> in the database results class now returns column type and length.</p></li>
<li><p>Default .htaccess file updated to work better with extended characters.</p></li>
<li><p>New Testing Feature: <a class="reference internal" href="../testing/fabricator.html"><span class="doc">Fabricator</span></a> makes creating mock classes simple and repeatable in your tests.</p></li>
<li><p>Model class can now have the callbacks overridden at runtime. Useful for testing.</p></li>
<li><p>A number of improvements to <a class="reference internal" href="../testing/feature.html"><span class="doc">Feature Tests</span></a> in general.</p></li>
<li><p>New <a class="reference internal" href="../cli/spark_commands.html"><span class="doc">command() helper function</span></a> to programatically run your CLI commands. Useful for testing and cron jobs.</p></li>
<li><p>New command, <code class="docutils literal notranslate"><span class="pre">make:seeder</span></code> to generate a <a class="reference internal" href="../dbmgmt/seeds.html"><span class="doc">Database Seed class</span></a> skeleton file.</p></li>
<li><p>Colors now available on the CLI within Windows, as well as other Windows-related CLI improvements.</p></li>
<li><p>New helper <a class="reference internal" href="../helpers/url_helper.html"><span class="doc">mb_url_title()</span></a> that functions like <code class="docutils literal notranslate"><span class="pre">url_title()</span></code> but automatically escapes and extended URL characters.</p></li>
<li><p><a class="reference internal" href="../libraries/images.html"><span class="doc">Image library</span></a> now supports <code class="docutils literal notranslate"><span class="pre">webp</span></code> images.</p></li>
<li><p>Added Unicode support for regular expressions in the Router.</p></li>
<li><p>Added support for removing hidden folders in the <a class="reference internal" href="../helpers/filesystem_helper.html"><span class="doc">delete_files()</span></a> helper.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">fetchGlobal()</span></code> in the Request class now supports applying filters to arrays of data, not just the first item.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">file</span></code> validation now works with arrays of files.</p></li>
<li><p>URI class now supports a <code class="docutils literal notranslate"><span class="pre">setSilent()</span></code> method that will disable the throwing of Exceptions.</p></li>
<li><p>New argument to <code class="docutils literal notranslate"><span class="pre">URI::getSegment()</span></code> that allows us to change the default value returned if nothing exists.</p></li>
<li><p>Implemented a <code class="docutils literal notranslate"><span class="pre">withResource()</span></code> in Image so that you can use method chaining instead of using the provided getResource() (used in tests). To just compress your image.</p></li>
