Help search, in the help centre, the Help drawer and the search box, now matches what you type when something has gone wrong, such as booking page says not found or reminder did not fire, as well as an article's title and the other names for the thing. A match in a title or a name ranks above a match in the text, and every word you type has to appear in the article.
An article page shows the rest of its section beside it with the current article marked, an On this page list when the article has several sections, and an Open this in Magpie link to the page the article is about.
Numbers in Help such as file size limits are read from Magpie itself, so an article can no longer state a limit that has changed.
A Changelog entry now links to the Help article that covers the change, under its summary.
