# Changelog

Every change to a computed value is a breaking change and needs a major version of the format it touches; see [spec/00-introduction.md](spec/00-introduction.md).

## 0.1.0

The first release, written for level 3 so that formats never change as the studio moves up.

- Chapters 0 to 22, covering every format the design names.
- 37 JSON Schemas, restricted to a keyword subset that independent validators read alike.
- Tables for SQLite, Dolt and PostgreSQL, a team store, and the SQLite bundle with FTS5.
- The JSON-LD context for layers, and registries of formats, rules, stamp rules and stage defaults.
- Vectors for canonical JSON, normalization, IDs, notation, both projections, offsets, the five values, addresses, keyed hashes, page fingerprints, Merkle roots, signatures, spot-checks, error bounds, alignment, every correction, anchor resolution, rights and grading.
- Packages for the three M1 fixtures (two sections of a converted chemistry paper with a multi-level-header table, an open-access paper and a short Typst draft), a checks-only export, and a tiny document; records of every other format; and seventeen invalid packages.
