Xindice Supported?

Hi Fellow Xindice Users,
I am a new user and I would like to use Xindice in my project but 
looking at the age of Xindice1.1b4 I am concerned that Xindice is no 
longer being actively developed and/or supported and that there will 
never be a stable release of Xindice 1.1 available.  I am wondering if I 
should I use 1.1b4 for production code or not.  Should I use 1.0 
instead?  Should I not use Xindice at all.  Does anyone have an opinion 
on the above and/or experience that would help me decide.
Thanks in advance,
Jon Oakes
