<p><em>Sourced from <a

releases</a>.</em></p>
<blockquote>
<h2>v1.15.6</h2>
<ul>
<li>Restore pervious text clearing selection behaviour on
fallback-enabled sortable lists. Text should be cleared whenever mouse
is down on a sortable item, but text inputs within items should still be
interactable</li>
<li><a
href="https://redirect.github.com/SortableJS/Sortable/issues/2244">#2244</a>:
Fix issue where multi-drag selection doesn't work on IOS devices</li>
</ul>
<h2>v1.15.5</h2>
<ul>
<li><a
href="https://redirect.github.com/SortableJS/Sortable/issues/2410">#2410</a>:
Further improvements to handling of text selection during drag, to allow
text inputs to continue to function within sortable items. Removed the
previous <code>nextTick</code> solution which caused text inputs to be
noninteractive, and instead have moved the text selection clearing to
the actual drag start.</li>
</ul>
<h2>v1.15.4</h2>
<ul>
<li>Fix issue where text selection occurs during dragging when fallback
is enabled</li>
<li>Improved support for pointer events</li>
<li><a
href="https://redirect.github.com/SortableJS/Sortable/issues/1897">#1897</a>:
[MultiDrag] Prevent multi-select of non-draggable and filtered
items</li>
</ul>
