+Use of STL containers by default
+--------------------------------
+
+wxWidgets uses STL containers for the implementation of wxVector, wxList,
+wxDList and wxStack by default since 2.9.2 release. While the STL-based
+versions are mostly compatible with the old ones, there are some differences:
+
+ - wxList::compatibility_iterator must be used instead of wxList::Node* when
+   iterating over the list contents. The compatibility_iterator class has the
+   same semantics as a Node pointer but it is an object and not a pointer, so
+   you need to write
+
+        for ( wxWindowList::compatibility_iterator it = list.GetFirst();
+              it;
+              it = it->GetNext() )
+            ...
+
+   instead of the old
+
+        for ( wxWindowList::Node *n = list.GetFirst(); n; n = n->GetNext() )
+            ...
+
+ - wxSortedArrayString and wxArrayString are separate classes now and the
+   former doesn't derive from the latter. If you need to convert a sorted array
+   to a normal one, you must copy all the elements. Alternatively, you may
+   avoid the use of wxSortedArrayString by using a normal array and calling its
+   Sort() method when needed.
+
+ - WX_DEFINE_ARRAY_INT(bool) cannot be used because of the differences in
+   std::vector<bool> specialization compared with the generic std::vector<>
+   class. Please either use std::vector<bool> directly or use an integer array
+   instead.
+
+Finally notice that you may set wxUSE_STD_CONTAINERS to 0 when compiling
+wxWidgets to use the non-STL containers.
