+- Update to version 0.5b1: 
+  + Introduce a new kind of adapters that rely on the framework routing.
+    Adapters are provided for Pecan, TurboGears and cornice.
+  + Reorganised the rest protocol implementation to ease the implementation
+    of adapters that rely only on the host framework routing system.
+  + The default rest @expose decorator does not wrap the decorated function
+    anymore. If needed to expose a same function several times, a parameter
+    multiple_expose=True has been introduced.
+  + Remove the wsme.release module
+  + Fix == operator on ArrayType
+  + Adapted the wsme.sphinxext module to work with the function exposed
+    by the wsme.pecan adapter.
+  + Allow promotion of int to float on float attributes (Doug Hellman)
+  + Add a samples_slot option to the .. autotype directive to choose where
+    the data samples whould be inserted
+  + Add sample() to ArrayType and DictType
+  + 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
+  + Fix empty/nil strings distinction in soap
+  + Improved unittests code coverage.
+  + Ported the soap implementation to python 3.
+  + Moved non-core features (adapters, sphinx extension) to the wsmeext module.
+  + Change the GET parameter name for passing the request body as a parameter
+    is now from ‘body’ to ‘__body__’
+  + The soap, extdirect and sqlalchemy packages have been merged into the
+    main package.
+  + Changed the documentation theme to “Cloud”.
