ostreedev/ostree v2026.1

on GitHub

This release includes several important bug fixes, most notably fixing
soft-reboot handling for var, sysroot, and boot mounts, and
preserving extension BLS keys across staged deployments. The libarchive
integration now correctly handles UTF-8 filenames without locale
dependency, and the dracut module was fixed to use the correct systemd
unit directory. On the features side, ostree admin status --json now
includes the deployment origin refspec.
The CI infrastructure saw a significant overhaul: Packit CI was added
with RPM builds and TMT integration tests, the test-tmt shell script
was replaced with a Rust xtask, and Justfile targets were introduced
for local development workflows.
