Release Notes: Optional prefix truncation (previously prefixes with non-zero host bits were dropped with a warning), and a quiet flag to suppress warning messages.
Release Notes: Changing parsing semantics on IPv4 addresses to bring them in line with reality.
Release Notes: The aggregate-ios script is now written in Perl, since the availability of particular awk features can't be guaranteed across platforms. The build process now uses autoconf. Minor tweaks were made to the default values of -m and -n to make more sense in a general application.
