The main highlights (for me) are support for `backup --read-concurrency` to control the I/O pressure on the underlying file-system and disks and `backup --no-scan` which also helps. (I'll have to test these options myself, plus the compression from `0.14`.)<p>The other highlight is the `rewrite` command which allows you to remove (or include) files in a former snapshot without a complete re-backup.
