Kubuntu lead developer Jonathan Riddell has sent out an announcement that
Canonical will no longer be funding work on the KDE-based Kubuntu
distribution. “The practical changes are I won’t be able to work on KDE bits in my
work time after 12.04 and there won’t be paid support for versions
after 12.04. This is a rational business decision, Kubuntu has not
been a business success after 7 years of trying, and it is unrealistic
to expect it to continue to have financial resources put into it.“
