<p>This release includes all features that were previously exclusive to the
Insiders edition. These features are now freely available to everyone.</p>
<p>Note on deprecated plugins: The projects and typeset plugins are included in
this release, but must be considered deprecated. Both plugins proved
unsustainable to maintain and represent architectural dead ends. They are
provided as-is without ongoing support.</p>
<p>Changes:</p>
<ul>
<li>Added support for pinned blog posts and author profiles</li>
<li>Added support for customizing pagination for blog index pages</li>
<li>Added support for customizing blog category sort order</li>
</ul>
