Yes, we are not going to release Parsidora 17. While we did almost all of the work, and passed a number of difficulties (some of them are explained in my blog) we faced a bug in the installer which prevented us from building working installation media.
As Fedora 18 is going to released soon, we decided to stop spending time on Parsidora 17 and start working on Parsidora 18 instead so we can have a better and more interesting release. :)
P.S. Parsidora 17 repository is available at http://parsidora.sourceforge.net/releases/17/repos/parsidora/ and can be added to Fedora 17 to use the extra packages available in it.
