     reduced-convolution method. In particular, correctly handled the case where
     one of the summands does not have an outer boundaey.
 
+### 3D Point Set
+
+-   Added a method `copy_properties()` that allows to copy the
+    properties from a point set to another one (without copying the
+    content);
+
+-   Added a method `insert(const Point_set&, const Index&)` to copy a
+    point along with all its associated properties from another point
+    set;
+
+-   `remove()` methods now only invalidate the `end()` iterator
+    instead of invalidating all iterators;
+
+-   Added a method `is_removed()` that takes an index as argument;
+
+-   Added a method `cancel_removals()` to restore removed points (if
+    no point was inserted since then an garbage was not collected);
+
+-   **Breaking change:** unified API of method `add_normal_map()` with
+    `add_property_map()`: it now returns a pair of property map + bool
+    (that tells if the property was added) instead of just the
+    property map;
+
+-   Added a method `properties_and_types()` in addition to
+    `properties()`: this new one returns pairs of `std::string` +
+    `std::type_info` in order to also know the type of each property.
