Kubuntu 9.04 will have KDE 4.2 which has some of the little problems that KDE 4.1 had fixed. It also looks different again from the 8.10 release as more artwork was added. The desktop now has a “spotted” background. KDE 4.2 offers new and improved applications.
Plasma, Kwin, and the KDE workspace have been refined. For the people that like the eye candy, they have improved existing and new plasmoids, which is what the desktop widgets are called in KDE.
The focus for the Kubuntu team will lay on producing a clean and smooth KDE4 experience in 9.04.
New and Improved Applications
Konversation will not be included any more. Konversation is the IRC client in Kubuntu. Quassel will be its replacement.
Amarok 2 will be in this version of Kubuntu. I've been using Amarok 2 for a while now and must say it's a great improvement. (See the second screen shot below.)
If you haven't used it before then you might not know that Kubuntu 8.10 didn't have Digikam anymore. Digikam is the photo management tool in KDE. It’s an awesome program I have been using ever since I started using Kubuntu. Digikam didn't release a KDE4 version before release of Kubuntu 8.10 so it was left out. In Kubuntu 9.04, Digikam 0.10.0 is introduced. Finally, the KDE4 version of Digikam that we have been waiting for will be included. That’s great because it's one of the best photo managers for Linux out there.
It looks like Kubuntu Jaunty Jackalope or 9.04 will be one of the best KDE4 releases to date.
April 23, 2009: Jaunty is released see my new article here.
