Just a few days after the 2.4.2 release you'll get the 2.4.3 release.
I should know that you should not do larger changes to the build
system between the final beta and the release. So, I screwed up. The
--with-ical-support=no option did not really work. As the fix is
important to keep TaskJuggler 2.x on current Linux distros, I've
decided to go for a 2.4.3 release. If 2.4.2 works for you, don't
bother updating to 2.4.3. There are no functional changes, just fixes
to build TaskJuggler without KDEPIM3.
TaskJuggler 2.4.3 can be downloaded from the download page:
