+*   New syntax for object arrays as GET parameters, without brackets. Ex:
+    ``?o.f1=a&o.f1=b&o.f2=c&o.f2=d`` is an array of two objects:
+    [{'f1': 'a', 'f2': 'c']}, {'f1': 'b', 'f2': 'd']}.
+
+*   @signature (and its @wsexpose frontends) has a new parameter:
+    ``ignore_extra_args``.
+
+*   Fix boolean as input type support in the soap implementation (Craig
+    McDaniel).
+
+*   Fix empty/nil strings distinction in soap (Craig McDaniel).
+
+*   Improved unittests code coverage.
+
+*   Ported the soap implementation to python 3.
+
+*   Moved non-core features (adapters, sphinx extension) to the ``wsmeext`` module.
