Every changelog entry now has its own page

The changelog opens with the ten most recent updates in full; everything earlier is listed below them as a single line with its date and type, and each one links to a page of its own. Those pages have a stable address you can share or bookmark, and the RSS feed now links to them. Links you already saved to an entry on the timeline still land on it. The page itself is a fraction of its former size, so it opens noticeably faster on a phone.
