These seem to all be coalesced in the changes.in source file. Sometimes links in the form of <a href="https://www.sqlite.org... get translated in the output as <a href="../https://www.sqlite.org.... This naturally causes the resulting links to be 404s.

Thank you for the report. That's now resolved in the docsrc trunk but the changes won't go online until the next time the site is built.
