• zoned mode: open host-managed devices with direct io, page cache cannot be used for synchronization due to ordering
• convert: set creation and change time of the root subvolume
• mkfs:
  • set creation and change time of the created subvolumes
  • make -O mixed work same as --mixed, so it does not create split block groups by mistake
  • for reproducible builds, honor SOURCE_DATE_EPOCH, SEED and for --rootdir order the files deterministically
• corrupt-block: allow inode and dir item corruption to use option --value
• check:
  • detect file extents for wrong inode types
  • on zoned filesystem, detect leaked active zones
• restore: handle inline extents larger than 4KiB, e.g. created on systems with 64KiB pages
• build:
  • minimal version of util-linux is 2.31
• scrub limit: set to the original limit only after all devices finish
• other
  • new and updated tests
  • documentation updates
