Xournal++  landed on Fedora a month ago and can be considered as the
successor of Xournal. The author of Xournal even recommends it due
its more active development and its compatibility of the format. For
that reason, Xournal++ will replace Xournal on the next release of
Fedora Design Suite.
Development release with latest features is also available on
