About these recaps

Assembled from our own archive of 551 stories, which currently runs from 4 October 2023. Ranking is by the impact score described on the front page — an estimate of how much a story is likely to affect one website, not a measure of how much attention it got.

The archive only holds what it has seen. Periods before it started are empty rather than quiet, and it gets more complete every week it runs.
