Looking for rspec learning resources

I am at the point in my Rails learning journey where I need to cross
the rspec river and need instructions on how to build a boat.
Having spent a year learning Rails, one of the biggest traps has been
the waste of effort caused by reading outdated material.
I see David’s page, which looks great, is dated May 14th 2007. Can
anyone tell me if there are any parts of that page that have changed
due to newer releases?
I have the Peepcode movies and Obie’s “The Ruby Way”, both of which
seem to have good info. Are there any other current resources out
there that y’all recommend

Thanks in advance.
