+ - The --append option's restricting of transfers to those that add data no
+ longer prevents the updating of non-content changes to otherwise up-to-
+ date files (i.e. those with the same content but differing permissions,
+ ownership, xattrs, etc.).

+ - Don't allow --fake-super to be specified with -XX (double --xattrs)
+ because they conflict. If a daemon has "fake super" enabled, it
+ automatically downgrades a -XX request to -X.
