[ubuntu-studio-users] Ubuntu Studio 13.10 ---> 14.04 (a question)

[Henry W. Peters]

Been using UBS for about a year... on a USB 3 external HD, & dual boot 
with Windows 8.1 (v. 1310.10 USB currently).

Two questions that I have concerning the most recent version (14.04):

1). Why is it not the upgrade path recommended (i.e.  via Software 
Updater)?

2). What are significant differences between these two versions (i.e., 
why update or upgrade)?

Thanks for any insights.
