The only thing the change does is the way the manpage gets parsed, and fixes
follwing warning.
"W: dhcpd-pools: groff-message an.tmac:<standard input>:147: warning: tbl
preprocessor failed, or it or soelim was not run; table(s) likely not
rendered (TE macro called with TW register undefined)

When --warning or --critical thresholds are defined with text output lines
that exceed threshold will be either yellow (warning) or red (critical).

Current output makes some false-positives for situations when multiple
ranges are specified inside single network, for example:
subnet 10.0.0.0 netmask 255.255.254.0 {
...
range 10.0.0.1 10.0.0.254;
range 10.0.1.1 10.0.1.253;
...
}
An alert for range 10.0.0.1 - 10.0.0.254 will be raised even in situations
when range 10.0.1.1 - 10.0.1.253 is completely empty. To cope with this
issue, an -A option is added to treat all single networks as shared-network.
This option changes output for both range and shared networks output if
specified. Frankly saying, using network CIDR as network name is much more
sane for me than 'All Networks'.

Incomplete html page, that was just a html table, was removed some time ago
but deprecated option arguments were unfortunately left to manual that are
now removed.

Options -p or --perfdata (in alarming mode) now enable the output of
additional performance data, i.e. used, touched and backup addresses per
subnet.

This make the table output good looking, and allows users to click table
headings to sort data by column without rerunning the analysis.
Unfortunately this change is breaking change, meaning the old CSS tags are
no longer supported, nor partial html output that printed only the table.

Alarm criteria based solely on percentage was found to be difficult to be
tricky to setup in environments that has small ranges and big shared-nets
mixed up together. These two new options should help making alarming more
useful.

Some have configuration which combines small ranges such as one host, and
greater address ranges that are important to monitor. Especially the one
host ranges tend to cause a lot of false-positive alarms, as they are
immediately 100% full when a machine requests an address.

The prof. Xing Li in Tsinghua University, with LI Zimu, asked Cheer to
make the dhcpd-pools more usable for them which I, as a project
maintainer, could not be more pleased. Whils making the IPv6 analysis to
work Cheer also fixed various other issues. Kudos to him, and big thanks
to everyone.

The help screen has now same notation as most of the GNU/Linux
utilities, e.g. if a option requires argument it is marked as
