Preview 3 is out:
ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.6-preview3.tar.gz

I used it for the earlier benches and it has posed no problems for any
of my Rails apps in development.

Be sure to work with Rails' 1-2-stable branch (or edge) for a
smattering of 1.8.6 compatibility fixes due out in the upcoming Rails
1.2.3.
