Changes
What changed, and when
Every time a figure on this site changes, the previous data file is archived and the difference is recorded here. Nothing is edited in place.
Some revisions are missing. Early on, archive files were named by date only, so two revisions on the same day overwrote each other. These are gone:
- 2026-10-24 · rev 2 — overwritten by a later revision on the same day
- 2026-10-24 · rev 3 — overwritten by a later revision on the same day
The history below compares the revisions that survived. The naming has been fixed, so this cannot recur.
A further 6 revisions changed only wording or sourcing, not any figure, and are not listed separately.
