Changelog: every data build, with the numbers that moved
Every time the dataset is rebuilt, one line is appended here: the date, the data pass it belongs to, and how the tracked counts moved against the previous build. Nothing is edited or removed after the fact — if a number changed, you can see it and the date it changed on.
Build record
Started 2026-10-15. Each entry is generated from the live dataset at build time; the “what changed” column is computed against the previous entry, not written by hand.

Why this page exists
A comparison site that only shows current numbers cannot be audited. This log is the audit trail: it ties every published figure to a dated build, so a claim on the about page or in the methodology can be checked against what the dataset looked like on any given date. When an issuer changes pricing or a range starts declining, the next build records the move here rather than silently replacing the old figure.
