Ark has had a lot of bug fixing in this release, but some bits of new
stuff has indeed been done:

* Support for lzma/xz files has been added if kdelibs supports it
* Mimetype detection and selection has been improved and made easier
* We now rely on command-line tools for zip, rar and 7zip files, which
should fix a lot of weird bugs and make us more compatible with these
file formats
* Drag'n'drop support has been implemented
