Subject: rake published rdoc version and arity of Rake::Task#execute - wrong number of arguments (0 for 1)

Does anybody know if there is a reason why the rdoc for the rake gem
[1] is currently at version 0.7.x while the gem itself is at 0.8.1?

This caused me a bit of pain today when diagnosing a problem caused by
the change to Rake::Task#execute method which used to not take any
arguments, but now takes a single argument. I've posted the stack
trace below in case it saves anyone else a bit of pain.

Also, does anyone know why a single argument is now *required*? I've
found I can pass in nil as the argument and my rakefile works.

Thanks.
