I’ve just finished tagging a new release of Substruct, the open-source Ruby on Rails e-commerce and cms engine.
For the particulars, visit: http://sublog.subimage.com/articles/2007/11/17/substruct-0-95
There are tons of new features and an update UI. If you haven’t checked it out recently, now is the time.
Version
1.0 should be out before year’s end – including an easier way to
install for n00bz to rails, amongst other things. I’m really bad with
version numbers – this thing has been out about two years now and I
still haven’t felt comfortable calling it 1.0
