dash vs. ash?

[Robert Klemme]

All,

I just notice that there is dash in cygwin 1.7 but there is also ash.
What would be the reason to switch from ash to dash?  From what I am
finding on the web it seems, dash was basically ash code modernized.
So it seems when on 1.7 dash would be the preferred one.  Any insight?

Kind regards

robert
