Raptor
At last, got another release of raptor out the door after about 5 months and lots of changes (new RDF datatyping, collections, URI updates, internal improvements, bug fixes). It took a while till it had the features I wanted to add, the changes I wanted to make internally and after all that, to make it stable and working.
Releasing software is such a pain, especially in the free software / open source world. Since in particular, it is your reputation that is being demonstrated - "show me the code!" - and the source code you make available to the world is what counts.
Of course, talking about reputation on advogato is just asking for trouble. :)
