As I think I have said before, it is hard to find changelogs for Prey. Eventually I discovered https://updates.preyproject.com/en/, though UBlock Origin - the web’s most popular adblocker, I believe - seems to break the page (and the page has ‘What’s new on Prey’ which is bad - nonsensical - English).
Also, I note that, at present, the main Prey website seems to contain no link at all to this forum (or at least that is so for the front page of the main site).
Also: the text in this text book is too faint for many people to read easily.
