I'd think we should have two links. One to the latest official specs,
even though it is behind a login wall. And one to the latest free
version. For that, I think the archieve.org address which Wikipedia uses
is more stable thant the pololu address from above:

What do you think?

Yes, I agree. Should I update the patch and re-send it?

Yes, please.
