+For the latest file format version (verison 3), `--map-user` and `--map-group`
+will have differing behavior if the first value specified is a name or a numeric
+id.  If a name is given to map to another value, then it will affect only the
+username/groupname for files/links/dirs in the archive. If a numeric id is given
+as the first value, then it will affect only the UID/GID fro files/links/dirs in
+the archive. For previous file format versions (version 2 and 1), either name or
+numeric id will have an effect since these older file format versions only store
+UID/GID.

 Fix data_structures/priority_heap iter function.
