The books carry a release date. It doesn't always move when the text does — so this checks every book daily and publishes what changed, announced or not.
This is kept by someone who loves this game and wants it to last. Thrune runs on rules that live in players' heads — you read what a spell or a skill does, build a character around it, and carry that understanding for months at a time. That works as long as the ground stays where you left it, or, when it moves, as long as everyone finds out together.
So the books get checked once a day, and the result is written down, dated, and left where anyone can read it. Most days there is nothing to report, which is what a well-run game looks like. When there is something, it goes up with the evidence attached, so you can read the change and judge it for yourself. Everyone gets the same information on the same day — players, marshals, and whoever is mid-argument about it at the next event.
Every day, each book is downloaded and its text reduced to a fingerprint: a short code that changes completely if so much as one word does. Nothing is reported unless that fingerprint moves, and that comparison is arithmetic rather than opinion — no one is deciding whether a change feels important enough to mention. When a book does change, the exact difference is worked out automatically, Claude writes a plain-English summary of it, and this page updates on its own. The raw difference is always published beneath the summary, so if a summary gets something wrong, you can see it for yourself — and the book titles above link straight to the originals. Don't take our word for anything that matters.
