Here is a short list of what exactly changed:
- made it run only single instance via KUniqueApplication
- make it store config and data in KDE directories
- added irc protocol service provider files for use in KDE
- removed Dock and Phonon notification support
- removed Web links preview support
- rebranded (incomplete, but mostly done)
Things that need doing:
- use KDE localiztion implementation
- the --url argument needed for the service does not actually join
- use KStyle instead of stylesheets?
- implement a help menu like other KDE apps
- integrate with various KDE parts?
