* MIGRATION
- If you are using raw targets, make sure to run the
"raw_suffix2sidecar" utility in each target directory.
* Support for btrfs-progs v4.13.2: adapt parsing of "btrfs sub list"
output (close #192).
* Add "resume" command, replacement for "-r, --resume-only" command
line option (which is now deprecated).
* Add "snapshot" command (close #150).
