This release stabilizes a new compose rootfs build workflow which is intended for use in container multi-stage builds; for more see its use in fedora-bootc.
There are also some minor tweaks for the rechunking tooling. The existing rechunking done as part of rpm-ostree compose image is stable, but we aim to stabilize the "separate rechunker" currently exposed via rpm-ostree experimental build-chunked-oci in a later release.
