<h2 id="minimum-requirements">Minimum requirements<a class="headerlink" href="#minimum-requirements" title="Permanent link">#</a></h2>
<p>The ECMAScript target version has been increased to ES2022 from es2017.</p>
<h2 id="subscribe-button-wcfuserobjectwatchsubscribe">Subscribe Button (WCF.User.ObjectWatch.Subscribe)<a class="headerlink" href="#subscribe-button-wcfuserobjectwatchsubscribe" title="Permanent link">#</a></h2>
<p>We have replaced the old jQuery-based <code>WCF.User.ObjectWatch.Subscribe</code> with a more modern replacement <code>WoltLabSuite/Core/Ui/User/ObjectWatch</code>.</p>
<p>The new implementation comes with a ready-to-use template (<code>__userObjectWatchButton</code>) for use within <code>contentInteractionButtons</code>:
<div class="highlight"><table class="highlighttable"><tr><td class="linenos"><div class="linenodiv"><pre><span></span><span class="normal">1</span></pre></div></td><td class="code"><div><pre><span></span><code><span class="cp">{</span><span class="nf">include</span> <span class="na">file</span><span class="o">=</span><span class="s1">&#39;__userObjectWatchButton&#39;</span> <span class="na">isSubscribed</span><span class="o">=</span><span class="nv">$isSubscribed</span> <span class="na">objectType</span><span class="o">=</span><span class="s1">&#39;foo.bar&#39;</span> <span class="na">objectID</span><span class="o">=</span><span class="nv">$id</span><span class="cp">}</span><span class="x"></span>
</code></pre></div></td></tr></table></div></p>
<p>See <a href="https://github.com/WoltLab/WCF/pull/4962/">WoltLab/WCF#4962</a> for details.</p>
<h2 id="support-for-legacy-inheritance">Support for Legacy Inheritance<a class="headerlink" href="#support-for-legacy-inheritance" title="Permanent link">#</a></h2>
<p>The migration from JavaScript to TypeScript was a breaking change because the previous prototype based inheritance was incompatible with ES6 classes.
<code>Core.enableLegacyInheritance()</code> was added in an effort to emulate the previous behavior to aid in the migration process.</p>
<p>This workaround was unstable at best and was designed as a temporary solution only.
<a href="https://github.com/WoltLab/WCF/pull/5041">WoltLab/WCF#5041</a> removed the legacy inheritance, requiring all depending implementations to migrate to ES6 classes.</p>
