| datasource | package     | from  | to    |
| ---------- | ----------- | ----- | ----- |
| npm        | strong-mock | 8.0.1 | 9.1.0 |


## [v9.1.0](https://github.com/NiGhTTraX/strong-mock/blob/HEAD/CHANGELOG.md#910-2026-01-13)

> \[!IMPORTANT]\
> The next major version (v10) will be ESM-only. Since Node 20.19 supports `require(esm)` by default (see [Node 20.19.0 release post](https://nodejs.org/en/blog/release/v20.19.0/#requireesm-is-now-enabled-by-default)), no changes should be required for CJS projects using Node 20.19 or higher.

##### Features

- Publish ESM build, alongside CJS ([f1ece16](NiGhTTraX/strong-mock@f1ece16))
  - This is in preparation for v10, which will be ESM-only. ESM projects should use the ESM build automatically, while CJS projects will continue to use the CJS build.
- Support nesting matchers in `deepEquals` (the default matcher) ([7c243d2](NiGhTTraX/strong-mock@7c243d2))
  - Example: `when(() => mockedFn({ foo: It.isNumber() }))`

##### Bug Fixes

- Fix diff integration with IDEs for vitest ([f881346](NiGhTTraX/strong-mock@f881346))

##### [9.0.1](NiGhTTraX/strong-mock@v9.0.0...v9.0.1) (2024-11-23)

##### Bug Fixes

- **deps:** update dependency jest-diff to \~29.7.0 ([50a3aa8](NiGhTTraX/strong-mock@50a3aa8))
- Pretty print nested matchers in `isArray` ([24f9deb](NiGhTTraX/strong-mock@24f9deb))


## [v9.0.1](https://github.com/NiGhTTraX/strong-mock/blob/HEAD/CHANGELOG.md#901-2024-11-23)



## [v9.0.0](https://github.com/NiGhTTraX/strong-mock/blob/HEAD/CHANGELOG.md#900-2024-05-27)

This version greatly improves error messages and the matcher API. Check the [migration guide](MIGRATION.md#migrating-to-v9).

```typescript
const fn = mock<(x: number, y: number, z: { foo: string }) => number>();
when(() => fn(1, 2, { foo: 'bar' })).thenReturn(42);

fn(1, 2, { foo: 'baz' });
```

##### Features

- Improve `isNumber` diff ([55647ed](NiGhTTraX/strong-mock@55647ed))
- Improve `isObject` diff ([5533bcf](NiGhTTraX/strong-mock@5533bcf))
- Improve `isString` diff ([5c73fbb](NiGhTTraX/strong-mock@5c73fbb))
- Improve `willCapture` diff ([7d92ce9](NiGhTTraX/strong-mock@7d92ce9))
- Improve colors in UnexpectedCall error message ([f326954](NiGhTTraX/strong-mock@f326954))
- Pretty print argument diffs in UnexpectedCall error messages ([ba4f6b5](NiGhTTraX/strong-mock@ba4f6b5))

##### Bug Fixes

- Fix `isPartial` allowing unexpected keys ([cc0b881](NiGhTTraX/strong-mock@cc0b881))
- Fix `isPartial` not working with interfaces ([169b336](NiGhTTraX/strong-mock@169b336))
- `isObject` now correctly fails for `null` and `undefined` ([9b50fe4](NiGhTTraX/strong-mock@9b50fe4))
- Fix `It` docstrings ([df7f91a](NiGhTTraX/strong-mock@df7f91a))
- Handle non string keys in `isObject` ([87cb768](NiGhTTraX/strong-mock@87cb768))
