 When invoked with these two options, tar 1.25 would add only the
 top-level directory to the archive, but not its contents.
 
+* Support for POSIX ACLs, extended attributes and SELinux context.
+
+Starting with this version tar is able to store, extract and list
+extended file attributes, POSIX.1e ACLs and SELinux context.  This is
+controlled by the command line options --xattrs, --acls and --selinux,
+correspondingly.  Each of these options has a `--no-' counterpart
+(e.g. --no-xattrs), which disables the corresponding feature.
+Additionally, the options --xattrs-include and --xattrs-exclude allow
+you to selectively control for which files to store (or extract) the
+extended attributes.
