Mistakes and changes

Details date. A page that was accurate when it was written can be out of date by the time it is read, and no undertaking is given that every page is current.

Sites linked from here

Pages elsewhere are revised on their owners' schedules, not this one's. A link that was accurate when it was added may point somewhere different now.

Amendments

Revisions are published here rather than announced individually. Reading the page is the way to see the current version.
