+### 3D Alpha Wrapping (new package)
+
+-   This component takes a 3D triangle mesh, soup, or point set as input, and generates a valid
+    (watertight, intersection-free, and combinatorially 2-manifold) surface triangle mesh
+    that contains the input.
+    The algorithm proceeds by shrink-wrapping and refining a 3D Delaunay triangulation,
+    starting from a loose bounding box of the input.
+    Two user-defined parameters, alpha and offset, offer control over the maximum size of cavities
+    where the shrink-wrapping process can enter, and the tightness of the final surface mesh
+    to the input, respectively. Once combined, these parameters provide a means to trade fidelity
+    to the input for complexity of the output.

 ### [dD Spatial Searching](https://doc.cgal.org/5.5/Manual/packages.html#PkgSpatialSearchingD)
 
 -   Added the member function `write_graphviz()` to the class The Kd_tree` that writes the tree in a stream in the [Graphviz](https://graphviz.org/) format.
