"Robert Myers <mystinar AT comcast.net>: When KDE 4 is released next month, will packages for it be added to the Fedora 8 repositories?"
Robert, here's the cliff's notes answer:
KDE4 development platform is already in Fedora 8. For details:
When KDE 4.0 is released, we are strongly considering including KDE4 editions of kdeedu, kdegames as well, but the final decision hasn't been made.
The rest of KDE4 is Fedora 9 territory:
which is currently a bit out of date, but we'll be working on that once Fedora 8 is out the door.
