The release candidate for DOSBox Staging 0.81.0 is out. I have packaged it in COPR. Please test it and report any issues. Obvious upstream issues can be reported straight upstream, while potentially Fedora specific items can be reported in this thread, or to me personally.
sudo dnf copr enable oturpe/dosbox-staging
# One of there, depending on if you already have dosbox-staging
sudo dnf install dosbox
sudo dnf upgrade dosbox
