It means lots of new changes and lots of bug fixes. One of the best new features is the new filter options which now clearly says which filter you are currently using and an option to re-apply previously applied filters.
Now, there are still lots of ideas in my head for new features and improvements that can be done. I18N is hot but going to take some time since it's quite an involved change which might break certain parts.
The real issue tracker still has some 17 open issue but most of them are potential improvements that one can live without for the moment.
