Version 0.9.66 was released over a year ago! Upsteam is already at version 0.9.70 containing a ton of bug and probably _security_ fixes. What's going on? Is this package no longer maintained?
firejail-0.9.70-1.fc36 has been pushed to stable on September 15th. https://bodhi.fedoraproject.org/updates/FEDORA-2022-e8e9b50a33
