When I reported an error I’d noticed in the HyperSpec to Lispworks three years ago their response pointed me at the CLiki page, so I suspect that is probably the best source of errata available. And, more importantly, that response seems to imply they have no interest in updating the HyperSpec. That said, I remain grateful to them that it is available, even in its ossified form.
