apt upgrade

[John]

I did a bit of testing.  Before running an upgrade you will need to hold back the antiX package that will update the desktop application defaults.  If not it will override the default terminal, browser and editor so those menu items will not work any longer.  It will override without checking what is installed.

To avoid this open up a terminal and paste in this command:
sudo apt-mark hold desktop-defaults-antix

In the next alpha release I will make sure this is already taken care of.
