  1. Download our copy with the link above. 1 page of it is replaced by a note, because the original’s names members of the public.
  2. Work out the file’s fingerprint. Mac or Linux: shasum -a 256 the-file.pdf. Windows: certutil -hashfile the-file.pdf SHA256.
  3. It should give the first fingerprint above: the copy’s own.
  4. The second is the file as we fetched it from the publisher. A copy from the publisher’s own site gives it only if they have not changed their file since.

A fingerprint shows a file has not changed. It is not encryption. How this works

How to read this page

  1. Every figure is as the document prints it, with the page it is on where the document has pages.
  2. A date links to its own page, with everything else that changed that day.
  3. Old figures are kept, never overwritten. A notice page lists what the notice set, even after a later one replaced it.
  4. Hatching means we hold no copy. Such a source is cited only, and its page says so.
