<summary>jsdoc/jsdoc</summary>

### [`v4.0.0`](https://togithub.com/jsdoc/jsdoc/blob/HEAD/CHANGES.md#&#8203;400-November-2022)

[Compare Source](https://togithub.com/jsdoc/jsdoc/compare/3.6.11...084218523a7d69fec14a852ce680f374f526af28)

-   JSDoc releases now use [semantic versioning](https://semver.org/). If JSDoc makes
    backwards-incompatible changes in the future, the major version will be incremented.
-   JSDoc no longer uses the [`taffydb`](https://taffydb.com/) package. If your JSDoc template or
    plugin uses the `taffydb` package, see the
    [instructions for replacing `taffydb` with `@jsdoc/salty`](https://togithub.com/jsdoc/jsdoc/tree/main/packages/jsdoc-salty#use-salty-in-a-jsdoc-template).
-   JSDoc now supports Node.js 12.0.0 and later.
