Vim 8.1 is a minor release, a few new features have been added since Vim 8.0. The main new feature of Vim 8.1 is support for running a terminal in a Vim window, it sounds great for me.

So I decide to install Vim 8.1 on my main System.

sudo add-apt-repository ppa:jonathonf/vim
sudo apt-get update
sudo apt-get install vim
