# Change Log

## 1.8.0 Mar 6, 2026
- Added dual package outputs for npm consumers:
  - `module` now points to `dist/mod.js` (ESM)
  - `main` now points to `dist/mod.cjs` (CommonJS)
- Added `exports` map for explicit ESM/CJS/type resolution.
- Updated build scripts to emit both ESM and CJS artifacts via TypeScript.
- Updated constructor types so variants whose payload object has only optional fields can be called with no arguments.
- Added `"type": "module"` and retained CommonJS via `dist/mod.cjs` to improve Node ESM loading behavior.
- Limited published files to release artifacts (`dist`, README, LICENSE, CHANGELOG) and added `prepack` build step.

## 1.7.2 Oct 28, 2025
- Added better type checking for the `_.parse` and `.toJSON` methods.

- Minor bugfixes.
- README improvements.
- Added VueJS and Zod helpers.
- BREAKING: Wire format updated from `{[tag]: data}` to `{"tag": tag, "data": data}`.  `toJSON` and `_.parse` updated accordingly.
- BREAKING: Removed duplicate `key()` and `property` properties.  The use case of these is already available via `tag` and `data` properties.

## 1.6.2 July 10, 2025
