This release is mainly a bug fix release, which improves the overall stability of Porcupine. On the server side apart from a couple of annoying bugs being fixed, there is no new feature added. Unlike wise, QuiX includes quite a few important updates. It is now possible for the engine to render semi-transparent widgets by defining their opacity attribute. Drag and drop functionality is also supported by introducing draggables and droppables. Although this functionality is there, it is not yet utilized by the Porcupine desktop. Another new major productivity enhancement is that you can now define the QuiX namespace as the default one; this means that there is no need for namespace declaration (those strange "a:" before each node's tag name) for each one of the nodes of a QuiX document. There is also a new flow box widget, which automatically re-arranges its contained widgets in wrappable rows based on its size. Additionally, have a look at the custom QuiX widgets created for the Porcupine desktop. These widgets include ready made editors for the "Relator1" and "RelatorN" data types and a custom widget for editing each object's security descriptor. They will help you understand how to create your own custom widgets.
I hope you'll find this release quite stable and useful.
