<blockquote>
<h2>[12.42.2] 2026-07-01</h2>
<h3>Fixed</h3>
<ul>
<li><code>animateView</code>: Cropped group layers now animate
<code>border-radius</code> from the old to new radius.</li>
</ul>
<h2>[12.42.1] 2026-06-30</h2>
<h3>Fixed</h3>
<ul>
<li><code>animateView</code>: Old layer fade out now cancelled when
defining <code>.new()</code>.</li>
</ul>
<h2>[12.42.0] 2026-06-24</h2>
<h3>Changed</h3>
<ul>
<li><code>animateView</code>: Layers are automatically grouped to match
their DOM-hierarchy. New <code>.group(false)</code> method
opts-out.</li>
</ul>
<h3>Fixed</h3>
<ul>
<li><code>animateView</code>: Auto-crop is now aspect-ratio aware,
disabling crops for matching aspect-ratios.</li>
<li><code>animateView</code>: Disabled automatic
<code>border-radius</code> animation.</li>
</ul>
<h2>[12.41.0] 2026-06-23</h2>
<h3>Added</h3>
<ul>
<li><code>animateView</code>: Moves from Motion+ Early Access and alpha
to main library.</li>
<li><code>animateView</code>: <code>.add()</code> resolves a CSS
selector or <code>Element</code> to automatically generate, apply and
remove <code>view-transition-name</code>.</li>
<li><code>animateView</code>: <code>.new()</code> and
<code>.old()</code> configures values to animate on new and old
layers.</li>
<li><code>animateView</code>: <code>.layout()</code> can set a custom
transition on the size/position animation of the currently selected
elements.</li>
<li><code>animateView</code>: Group layers now automatically crop with
children set to <code>cover</code>, with <code>border-radius</code>
animating from old radius to new. <code>.crop(false)</code> disables
this behaviour.</li>
<li><code>animateView</code>: <code>.class(name)</code> tags currently
selected elements with a <code>view-transition-class</code> as a custom
CSS hook.</li>
</ul>
<h3>Fixed</h3>
<ul>
<li><code>AnimatePresence</code>: Prevent stuck exit animations when
children interrupt.</li>
<li><code>drag</code>: Child <code>e.stopPropagation()</code> no longer
break drag end.</li>
<li>Fixing Next.js OOM on Windows when importing via <code>motion</code>
package.</li>
<li><code>animateLayout</code>: Improve handling of parallel/interleaved
calls.</li>
</ul>
<h3>Changed</h3>
<ul>
<li><code>animateView</code>: <code>.enter()</code> and
<code>.exit()</code> now refer specifically to <code>new</code> and
<code>old</code> layers where there are no matching <code>old</code> or
<code>new</code> layers.</li>
<li><code>animateView</code>: Interrupted transition setups now return
resolved animation rather than throwing.</li>
</ul>
