About Apptainer
Apptainer 1.6 candidate adds delta images that rebuild only what changed.
Apptainer 1.6.0-rc.1 is the first feature drop since 1.5.0 in May. It adds overlay builds that store only the files changed against a base image, with a --basepath option that finds the base locally or in a registry at run time. It also builds data partitions from tar files, mounts archives directly, and turns ORAS registries into a managed target with multi-arch push, search, delete and tag. The 1.5 point releases in between were security and compatibility fixes, including a suid privilege escalation through CDI directories.
