KDE 4.1 RC 1 has been released and packages are available for Kubuntu 8.04, the Hardy Heron. These packages install to /usr/lib/kde4 and can be installed along side your existing KDE 3 installation.
This is a release candidate quality package and may yet prove to be unstable at times. This release will allow you to follow closely with what is going on in the KDE 4.1 branch.
The updated packages for Kubuntu 8.04 are located in the Kubuntu Member's KDE 4 Personal Package Archive (PPA) repositories. To update to the release candidate of KDE 4.1, please complete the following:
Some packages are still compiling. Run the above command periodically to check for new additions. kdeplasma-addons contains new Plasma fun.
Some packages may still be compiling, check back for updates.
There will be many bugs with this release and it is recommended that you do not file bug reports against the packages in this release. If you come across any issue which may be packaging related, it is recommended that you join the Kubuntu KDE 4 IRC channel (#kubuntu-kde4) and query those in the channel.
Thanks to Harald "apachelogger" Sitter for preparing these packages.
