What changed, and when

Updates

A plain-language record of what changed on this site and when. Data on this site is revised as official releases land, and corrections are made in public rather than quietly — so this page exists to make both visible. Every entry maps to a tagged release; the full technical detail, including internal refactors not worth listing here, is in the repository's CHANGELOG.

An independent check, August data, and three rendering fixes

Added an external study that reaches this project's governance conclusion by a different method, refreshed the data to August 2026, and fixed three display bugs — one of which had been hiding a chart's data entirely.

Added — An independent-corroboration section in Methodology covering Grier & Grier (2026), 'Promises, Promises'. They build a synthetic-control counterfactual over 1984-2013; this project builds composite indices from observed series. Different method, convergent conclusion — with the points of disagreement stated openly rather than smoothed over.
Data — CPI 2026 updated to 4.45% (MoSPI July 2026). Unemployment re-cited to the June 2026 PLFS bulletin — the headline 5.5% was unchanged.
Correction — MoSPI replaced the CPI 2012=100 index with 2024=100 from the January 2026 print, reweighting on HCES 2023-24. Food's weight fell from 45.86% to 36.75%, so headline CPI now responds less to a food-price shock than it used to. The 2026 figure is not on the same basis as 2014-2025 and is now labelled as such rather than silently spliced onto the older series.
Fixed — The Era Comparison detail chart had been rendering with no data line at all — a colour rule matched none of its points and made the whole series transparent. It now draws correctly, split into NDA-I and NDA-II.
Fixed — On phones the whole site was zooming out because one wide element stretched the page to roughly three times the viewport width. All fourteen tabs now fit a phone screen properly.
Fixed — Era shading and policy-event markers on the Interactive Data chart were never drawing.
Security — The two third-party scripts the site loads are now pinned with integrity hashes, so a substituted file on the CDN cannot execute.

2026-07-07 · v2.30.1

July data refresh

Routine refresh against the public releases available in early July 2026.

Data — Unemployment 2026 revised 5.1% to 5.5% (PLFS Monthly Bulletin, May 2026). CPI 2026 set to 3.93%.
Changed — Stale-date detection in CI widened, and the build's checkout action pinned to a single version across both workflows.

2026-06-18 · v2.30.0

Stylesheet precompiled; runtime CDN retired

The site stopped compiling its stylesheet in the browser on every visit and now ships a prebuilt one, with a guard so it cannot silently fall out of date.

Changed — Tailwind is compiled ahead of time into a committed stylesheet instead of being generated at page load. Faster first paint and one fewer third-party script.

2026-06-18 · v2.28.0

Indices rebuilt: COVID undercount, NSO merger, GST

The three constructed indices were rebuilt from a single canonical script so both political eras are computed identically.

Changed — The Statistical Suppression Index now includes the COVID mortality undercount and the NSO merger; the Fiscal Centralisation Index now treats GST as a structural shift in state taxing power rather than only counting cesses.
Method — Both the UPA and NDA decades are now generated by the same script, so no difference between the eras can come from how they were computed.
