<summary>Release notes</summary>
<p><em>Sourced from <a href="https://github.com/mkdocs/mkdocs/releases">mkdocs's releases</a>.</em></p>
<blockquote>
<h2>1.6.0</h2>
<h2>Local preview</h2>
<ul>
<li>
<p><code>mkdocs serve</code> no longer locks up the browser when more than 5 tabs are open. This is achieved by closing the polling connection whenever a tab becomes inactive. Background tabs will no longer auto-reload either - that will instead happen as soon the tab is opened again. Context: <a href="https://redirect.github.com/mkdocs/mkdocs/issues/3391">#3391</a></p>
</li>
<li>
<p>New flag <code>serve --open</code> to open the site in a browser.<br />
After the first build is finished, this flag will cause the default OS Web browser to be opened at the home page of the local site.<br />
Context: <a href="https://redirect.github.com/mkdocs/mkdocs/issues/3500">#3500</a></p>
</li>
</ul>
<h3>Drafts</h3>
<blockquote>
<p>[!warning]
<strong>Changed from version 1.5:</strong></p>
<p><strong>The <code>exclude_docs</code> config was split up into two separate concepts.</strong></p>
</blockquote>
<p>The <code>exclude_docs</code> config no longer has any special behavior for <code>mkdocs serve</code> - it now always completely excludes the listed documents from the site.</p>
<p>If you wish to use the &quot;drafts&quot; functionality like the <code>exclude_docs</code> key used to do in MkDocs 1.5, please switch to the <strong>new config key <code>draft_docs</code></strong>.</p>
<p>See <a href="https://www.mkdocs.org/user-guide/configuration/#exclude_docs">documentation</a>.</p>
<p>Other changes:</p>
<ul>
<li>Reduce warning levels when a &quot;draft&quot; page has a link to a non-existent file. Context: <a href="https://redirect.github.com/mkdocs/mkdocs/issues/3449">#3449</a></li>
</ul>
<h2>Update to deduction of page titles</h2>
<p>MkDocs 1.5 had a change in behavior in deducing the page titles from the first heading. Unfortunately this could cause unescaped HTML tags or entities to appear in edge cases.</p>
<p>Now tags are always fully sanitized from the title. Though it still remains the case that <a href="https://www.mkdocs.org/dev-guide/api/#mkdocs.structure.files.pages.Page.title"><code>Page.title</code></a> is expected to contain HTML entities and is passed directly to the themes.</p>
<p>Images (notably, emojis in some extensions) get preserved in the title only through their <code>alt</code> attribute's value.</p>
<p>Context: <a href="https://redirect.github.com/mkdocs/mkdocs/issues/3564">#3564</a>, <a href="https://redirect.github.com/mkdocs/mkdocs/issues/3578">#3578</a></p>
<h2>Themes</h2>
<ul>
<li>Built-in themes now also support Polish language (<a href="https://redirect.github.com/mkdocs/mkdocs/issues/3613">#3613</a>)</li>
</ul>
<h3>&quot;readthedocs&quot; theme</h3>
<ul>
<li>
<p>Fix: &quot;readthedocs&quot; theme can now correctly handle deeply nested nav configurations (over 2 levels deep), without confusedly expanding all sections and jumping around vertically. (<a href="https://redirect.github.com/mkdocs/mkdocs/issues/3464">#3464</a>)</p>
</li>
<li>
<p>Fix: &quot;readthedocs&quot; theme now shows a link to the repository (with a generic logo) even when isn't one of the 3 known hosters. (<a href="https://redirect.github.com/mkdocs/mkdocs/issues/3435">#3435</a>)</p>
</li>
<li>
<p>&quot;readthedocs&quot; theme now also has translation for the word &quot;theme&quot; in the footer that mistakenly always remained in English. (<a href="https://redirect.github.com/mkdocs/mkdocs/issues/3613">#3613</a>, <a href="https://redirect.github.com/mkdocs/mkdocs/issues/3625">#3625</a>)</p>
</li>
</ul>
