<blockquote>
<h2>[12.40.0] 2026-05-21</h2>
<h3>Added</h3>
<ul>
<li><code>path</code> option to <code>transition</code>.</li>
<li><code>arc()</code> for motion along an arc.</li>
</ul>
<h2>[12.39.0] 2026-05-18</h2>
<h3>Added</h3>
<ul>
<li>Support for <code>repeatType</code> and <code>repeatDelay</code> in
animation sequences.</li>
</ul>
<h3>Fixed</h3>
<ul>
<li>Variants: Re-run keyframe animations when switching between variant
labels even when they share identical keyframe arrays.</li>
<li>Drag: Preserve in-flight motion value animations across React 19
reorder unmount/remount so <code>dragSnapToOrigin</code> no longer
leaves the drag transform stranded after a layout swap.</li>
<li><code>LazyMotion</code>: Share React contexts between the
<code>framer-motion</code> and <code>framer-motion/m</code> (and
therefore <code>motion/react</code> and <code>motion/react-m</code>) CJS
bundles so that <code>&lt;m.div&gt;</code> from the <code>/m</code>
subpath picks up features loaded by <code>&lt;LazyMotion&gt;</code> from
the main entry point.</li>
<li><code>useScroll</code>: Support hydrating <code>target</code> and
<code>container</code> refs from anywhere in the tree.</li>
<li>Drag: Gesture no longer starts from incorrect start point when
rendered inside <code>&lt;AnimatePresence initial={false}
/&gt;</code>.</li>
<li>Drag: <code>dragConstraints</code>, when set as viewport-relative
ref, no longer break on scroll.§</li>
<li>Updated <code>visualElement</code> hydration order.</li>
<li><code>useAnimate</code>: Now respects
<code>skipAnimations</code>.</li>
<li><code>AnimatePresence</code>: Fix object-form <code>initial</code>
values not applied on re-entry after exit completes.</li>
<li><code>scroll</code>: Fixed callback progress when tracking an
element.</li>
<li><code>useScroll</code>: Fix hardware acceleration when tracking an
element.</li>
</ul>
