# Changelog

## 1.2.1, 2026-10-06

* Corrected the two "Upscaling & restoration" rows of k12-subcategory-rules.csv (Image & Visual, Video). The name exists in both categories and v1.2.0 showed their combined counts in both rows (123 block, 9 controls, 93.2% blocked). Recounted per category on 2026-10-06 from the same labels (124 and 15 tools): Image & Visual 114 block, 10 controls (91.9%); Video 13 block, 2 controls (86.7%). No other file or figure changed.

## 1.2.0, 2026-09-30

* Now holds only the sector data of the working paper: sector totals, the category defaults of all 15 sectors, verdicts per sector and category, pairwise disagreement, agreement across sectors and the complete K-12 rule set (18 categories, 165 subcategories, with rationale). The AI tool taxonomy and training-policy files are no longer copied in; they are their own dataset (doi:10.21227/hrxe-fa21).

## 1.1.0, 2026-09-30

* Rebuilt from AI tool taxonomy dataset v1.3.0 (corrected categories, verified training terms) with the sector totals used in the sector-policy paper, so dataset and paper report identical counts.

## 1.0.0, 2026-09-26

* First release: recommended block, controls and allow shares for 11,959 AI tools across 15 sectors.
* AI tool taxonomy with counts, category summary and aggregate vendor data-use terms.
