ENHANCEMENTS:
+ - Added the --specials option to tell rsync to copy special files (and does
+ not require root). The --devices option now affects just character and
+ block devices (which now matches the documentation). The -D option still
+ requests both --devices and --specials, and -a still infers -D.
+
- Added the --append option that makes rsync append data onto files
that are longer on the source than the destination (this includes new
files).
