OK I added this and I keep getting invalid format
foreach (@newValues){print "$_\n";}
my @versions;
while (@newValues)
{
chomp;
die "invalid format" unless
my ($major, $minor, $build) = /(\d+)(?:-.+)?\.(\d+)-(\d+)/;
push @versions, [ $major, $minor, $build , $_];
}
foreach (@versions){print "$_\n";}
}
