Yesterday I released a new Xpost version. But already today I am releasing another one, which also includes one new feature beneath bug fixes. The plugin contains now another small plugin which can be activated in the target blogs. It adds a widget displaying whether a post was crossposted. However this will only work with new posts. Old ones will show up as "not crossposted".
Moreover, I updated my QtHeaders plugin for Eclipse to the recent Qt version 4.6.3. The plugin is like Xpost hosted at gitorious.org, now.
