+[4.0.27]

+* mv no longer gets a failed assertion when moving a directory (specified with
+ a trailing slash) from one partition to another, and giving it a different
+ name at the destination.
+* `cp --link -f src existing-dest' no longer fails (bug introduced in 4.0z)
+* cp's new --remove-destination option now works with -R
[4.0z]

introduced in 4.0y)
