This release includes several important bug fixes, notably fixing a GVariant memory leak during opaque whiteout scanning that could cause bootc install to-disk to fail with EBUSY on unmount (#3595), and a crash fix for invalid UTF-8 ref names during pull operations (#3597). Kernel argument handling was fixed to properly handle quoted values in /proc/cmdline (#3583), and staged deployment bootconfig merging was corrected to preserve options across re-staging (#3587).

On the platform side, s390x SE boot image generation now uses the newer pvimg tool replacing the obsolete genprotimg (#3601). The CI infrastructure was modernized by removing the legacy Prow/Jenkins setup and switching to dnf-based RPM installation in test containers.
