Things to watch out for with zesty zapus 17.04 pre-alpha?

[JMZ]

Hi,

I went ahead and skipped yakkety 16.10 for pre-alpha zesty 17.04.  What 
should I look for as the development unfolds?  What would devel like to 
see for user input and critique?

The only big thing I'm waiting for is xubuntu-dev ppa (for example) to 
come online for zesty.  Until then, my xfce4 will probably lag behind 
yakkety users.
