Release candidate planning With each new release candidate, Qubes 4.1.0 becomes more stable as testers report bugs and our developers fix them. As explained in our general release schedule (www.qubes-os.org/doc/ver…n-scheme), this cycle will continue until no major bugs are discovered, at which point the last release candidate will be declared the stable 4.1.0 release. Until then, we plan to have new release candidates approximately every five weeks.
