Linuxcnc - Latest version update

I need to be pointed to any documentation that might be somewhat easy to follow in
updating my version of linuxcnc

When I modify an .nc file, when I save it, I then get asked if I want to save it.  I understand
this has been fixed with the update. 

I do not want to brick my machine.  It took me long enough to get it working perfectly. 
But I really would like to update the software if there is a smooth path to do this.

Thanks tons for any suggestions

 

Can you first tell us which version you are currently running?

2.8.2

2.8.2 to 2.8.4 should be automatic via the package manager.
