### v3.0.0

- There are no breaking changes (\*), but the distribution build process has changed:
  - ESM is built using [bun](https://bun.sh/);
  - DTS is built using [bun plugin Isolated Declarations](https://github.com/ryoppippi/bun-plugin-isolated-decl)
    that runs [oxc transformer](https://www.npmjs.com/package/oxc-transform) under the hood;
  - CJS is built using [tsc](https://www.typescriptlang.org/docs/handbook/compiler-options.html)
    and minified using [uglify-js](https://www.npmjs.com/package/uglify-js).
- (\*) — a peer dependency increase was found later and fixed in 3.0.1.

- The distribution becomes ESM first, while remaining dual (CJS support remains).
  - The right files should be chosen automatically from the `dist` folder:

- Features:
  - Performance improvement: 1.6 times faster.
