## [v9.2.0](https://github.com/NiGhTTraX/strong-mock/blob/HEAD/CHANGELOG.md#920-2026-02-12)

##### Features

- Allow mock name customization ([73c3b1c](NiGhTTraX/strong-mock@73c3b1c))
  - You can now name mocks with `mock<T>({ name: 'MyCustomMock' })` to help identify them in error messages.


## [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' });
```
