  785   User visible changes:
  786     * mkfs.btrfs --data dup
  787 
  788   People asked about duplicating data on a single device for a long time. There
  789   are no technical obstacles preventing that, so it got enabled with a warning
  790   about potential dangers when the device will not do the duplicated copies. See
  791   mkfs.btrfs section DUP PROFILES ON A SINGLE DEVICE.
  792 
  793     * support balance filters added/enhanced in linux 4.4
  794       * usage=min..max -- enhanced to take range
  795       * stripes=min..max -- new, filter by stripes for raid0/10/5/6
  796       * limit=min..max -- enhanced to take range
  797   Note: due to backward compatibility, the range maximum for 'usage' is not
  798   inclusive as for the others, to keep the same behaviour as usage=N .
  799 
  800     * manual pages enhanced (btrfs, mkfs, mount, filesystem, balance)
  801     * error messages updates, rewordings -- some fstests may break due to that
  802     * added support for free-space-tree implementation of space cache -- this
  803       requires kernel 4.5 and is not recommended for non-developers yet
  804     * btrfs filesystem usage works with mixed blockgroups
  805 
  806   Other:
  807     * installation to /usr/local -- this has unintentionally changed during
  808       conversion to autotools in 3.19

  810     * improved stability on fuzzed/crafted images when reading sys array in

  883 btrfs-progs-4.2.3 (2015-10-19)

  885     due to a reversed condition it returned immediately instead of waiting
  886   * scanning: do not scan already discovered filesystems (minor optimization)
  887   * convert: better error message in case the filesystem is not finalized

  899     * if nodesize was 64k, any metadata block was reported as crossing,
  900       this leads to mkfs failure for example due to "no free blocks
  901       found"
  902     * for other nodesizes, if the end of the metadata block was 64k
  903       aligned, it was incorrectly reported by fsck
