I had written about my COPR earlier . For sometime, I had not been updating it. Now, the COPR is up-to-date again.
The COPR xfce-414 can be enabled on Fedora 25+ using the command below –
- I am aware of some GTK-2 packages (e.g. claws-mail) under Applications menu show up out of place.
- The best theme to use with Xfce 4.13 is greybird. I recently pushed an updates to the testing repositories of Fedora 26  and 27  that addresses issues with Xfce 4.13.
