[Dave Dykstra]

apptainer-1.5.3 is now available in the epel-testing dnf repository and the Fedora updates-testing dnf repository. If no problems are found it will be promoted to the stable repositories in about a week. It is also now current in the Ubuntu PPA.

It can also be installed with "tools/install-unprivileged.sh -v 1.5.3'. For installation details see

> Apptainer 1.5.3 is now available. The changes are minor, mostly affect building images with special circumstances. One change is that if the `ptrace()` system call doesn't work, apptainer build doesn't try to make the image using PRoot. The other is that the fakeroot command (used mostly during builds, when subuid mapping is not available) now includes binding `getopt` from the host, to make it work with EL10 and Fedora base containers which no longer have it.
