Why does the newest version of Ubuntu (18.04) have 8 years old x11vnc?

My question is more specific than posted here and I have gotten an answer to it.

Ubuntu version:

user:~/$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04 LTS
Release:    18.04
Codename:   bionic

I have installed the x11vnc: 

sudo apt-get install x11vnc -y

Later I discovered the version is 8 years old.

X11vnc version

29/07/2018 17:15:54 x11vnc version: 0.9.13 lastmod: 2011-08-10  pid: 3283

So, I checked sources for the Ubuntu 18.04 and I see that the newest cersion is not available.

The current available version on the github is x11vnc 0.9.15 2018-02-04

Looking at https://packages.ubuntu.com/bionic/x11vnc i can see it's in 'universe', ie. community supported. This means no-one in the community has grabbed, compiled, tested & packaged the latest version.

You're welcome to do these if you can & wish, or you could 'file' a bug suggesting it be done too (when the MOTU & others find the time to do it).

The reason is not many in the community step forward & help, leaving it for a very small number of volunteers.

I have compiled and installed the new version of the x11vnc on my machine. The overnight testing has shown that it is more stable and doesn't have memory leaks observed in the older version.

Protocol

stop the current x11vnc if it is running

sudo systemctl stop x11vnc

get git if you don't have it

sudo apt-get install git

create a source folder in the home directory(or somewhere else if you want) and clone the new version of the x11vnc.

mkdir src
cd src
git clone git://github.com/LibVNC/x11vnc

you will get a new folder with x11vnc into it clone the x11vnc to your local machine

src/x11vnc

following the instructions in the readme file

Briefly, Building x11vnc: Make sure you have all the needed build/compile/development packages installed. On a Debian-based distro you can simply do

apt-get build-dep x11vnc

to install most of them.

if you get the error "You must put some 'source' URIs in your sources.list" the solution is here

To generate the build system, do a

autoreconf -fiv

After that, it's the usual

./configure
 make

install new x11vnc

user@user:~/src/x11vnc$ sudo make install

next, if you have added x11vnc to your autostart service list and followed this protocol you need to change location of your x11vnc service

sudo gedit /lib/systemd/system/x11vnc.service

change /usr/bin/ -> /usr/local/bin/

[Unit]
Description=Start x11vnc at startup.
After=multi-user.target

[Service]
Type=simple
ExecStart=/usr/local/bin/x11vnc -loop -forever -bg -rfbport 5900 -xkb -noxrecord -noxfixes -noxdamage -shared -norc -auth /run/user/120/gdm/Xauthority -rfbauth /etc/x11vnc.pass


[Install] 
WantedBy=multi-user.target

Got to config file and change to /etc/local/bin….

sudo systemctl daemon-reload
sudo systemctl start x11vnc

now you have new x11vnc 0.9.15 version

user@user:~/src/x11vnc$ /usr/local/bin/x11vnc -version
x11vnc: 0.9.15 lastmod: 2018-02-04

and the x11vnc server autostarts and uses the new versio

user@user:~$ systemctl status x11vnc
