Update to 0.4.1
This release fixes a privilege escalation bug pointed out by Stephen Röttger, where in some setups bubblewrap can be used to gain root permissions. Only version 0.4.0 is vulnerable, and only if installed setuid while at the same time the kernel supports unprivileged user namespaces. More details in the advisory here:
