I apologize in advance but I thought some of the rails users may be interested in this...
I just released web2py 1.20
www.web2py.com
You can see 5 min tutorial here
web2py Enterprise Web Framework - YouTube
and a 45min tutorial here:
web2py Enterprise Web Framework Tutorial on Vimeo
New features include the inclusion of a web based testing framework - a screenshot is here:

pyamf howto, rest support, handler for lighttpd/fcgi, WIKI helper, etc. AND it is always backward compatible since 1.0.
The source code is also on
code.google.com/p/web2py
Here are a dozen of ready made applications which you can install from the web interface without coding.
