All notable changes to this project will be documented in this file.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [Unreleased]

## [15.0.0]

### Changed

- **BREAKING:** Bump peer dependency on `@metamask/eslint-config` from `^14.0.0` to `^15.0.0` ([#431](https://github.com/MetaMask/eslint-config/pull/431))

## [14.0.0]

### Changed

- **BREAKING:** Bump minimum Node.js version from 16 to 18.18 ([#371](https://github.com/MetaMask/eslint-config/pull/371))
- **BREAKING:** Bump peer dependency on ESLint from `^8.57.0` to `^9.11.0` ([#370](https://github.com/MetaMask/eslint-config/pull/370))
  - ESLint 9 requires flat configs, so this change also rewrites the configs to
    use flat configs. The legacy config format is no longer supported.
- **BREAKING:** Bump peer dependency on `@metamask/eslint-config` from `^13.0.0` to `^14.0.0` ([#377](https://github.com/MetaMask/eslint-config/pull/377))
- **BREAKING:** Bump peer dependency on `eslint-plugin-n` from `^16.6.2` to `^17.10.3` ([#370](https://github.com/MetaMask/eslint-config/pull/370))
- **BREAKING:** Change package to be pure ESM ([#370](https://github.com/MetaMask/eslint-config/pull/370))
  - ESLint 9 supports ESM out-of-the-box, so this change updates the package to
    be pure ESM. This means that the package can no longer be used with CommonJS
    `require` syntax.

## [13.0.0]

### Changed

- **BREAKING**: Replace `eslint-plugin-import` with `eslint-plugin-import-x` ([#366](https://github.com/MetaMask/eslint-config/pull/366))
- **BREAKING**: Bump all ESLint dependencies ([#351](https://github.com/MetaMask/eslint-config/pull/351))
  - Bumps all ESLint dependencies to the latest version compatible with Node.js 16.
- **BREAKING**: Bump minimum Node.js version from 14 to 16 ([#332](https://github.com/MetaMask/eslint-config/pull/332), [#339](https://github.com/MetaMask/eslint-config/pull/339))

## [12.1.0]

### Changed

- Add support for typescript 5.0.x, 5.1.x ([#288](https://github.com/MetaMask/eslint-config/pull/288))

## [12.0.0]

### Changed

- **BREAKING:** Update peer dependency `@metamask/eslint-config` to v12
- **BREAKING:** Replace `eslint-plugin-node` with `eslint-plugin-n` ([#297](https://github.com/MetaMask/eslint-config/pull/297))

## [11.1.0]

### Changed

- Exclude test files from package ([#266](https://github.com/MetaMask/eslint-config/pull/266))

## [11.0.1]

### Fixed

- Disable import/no-nodejs-modules in Node.js config ([#257](https://github.com/MetaMask/eslint-config/pull/257))
  - This rule was added to the base config, but we accidentally forgot to disable it here.

## [11.0.0]

### Changed

- **BREAKING:** Remove no-undef in favour of custom environments configuration ([#254](https://github.com/MetaMask/eslint-config/pull/254))
  - This config now only allows globals that are available in Node.js.
- **BREAKING:** Bump all ESLint dependencies to the latest version ([#252](https://github.com/MetaMask/eslint-config/pull/252))
  - This includes peer dependencies.

## [10.0.0]

### Changed

- **BREAKING:** Update ESLint from v7 to v8 ([#233](https://github.com/MetaMask/eslint-config/pull/233))
  - This is breaking because `eslint` is a `peerDependency`.
  - Four new rules have been added:
    - [`no-loss-of-precision`](https://eslint.org/docs/latest/rules/no-loss-of-precision)
    - [`no-nonoctal-decimal-escape`](https://eslint.org/docs/latest/rules/no-nonoctal-decimal-escape)
    - [`no-unsafe-optional-chaining`](https://eslint.org/docs/latest/rules/no-unsafe-optional-chaining)
    - [`no-useless-backreference`](https://eslint.org/docs/latest/rules/no-useless-backreference)
- **BREAKING:** Update minimum Node.js version to v14 ([#225](https://github.com/MetaMask/eslint-config/pull/225))

## [9.0.0]

### Added

- **BREAKING:** Add JSDoc ESLint rules ([#203](https://github.com/MetaMask/eslint-config/pull/203))

## [8.0.0]

### Changed

- **BREAKING:** The peer dependency `@metamask/eslint-config` has been updated from v7 to v8.

## [7.0.1]

### Fixed

- Restore default `parserOptions` ([#193](https://github.com/MetaMask/eslint-config/pull/193))
  - By extending the recommended `eslint-plugin-import` rules, we accidentally changed the default `parserOptions.sourceType` to `module`.
    The `sourceType` is now explicitly set to `script`.
  - In some cases, `parserOptions.ecmaVersion` could also be set to an incorrect version.
    The `ecmaVersion` is now explicitly set to `2017`, matching the corresponding setting in `env`.

## [7.0.0]

### Changed

- Update install instructions in readme ([#185](https://github.com/MetaMask/eslint-config/pull/185))

### Fixed

- Add `@metamask/eslint-config` as a peer dependency ([#186](https://github.com/MetaMask/eslint-config/pull/186))
  - This package is designed to be used in conjunction with the MetaMask base ESLint config, so this should always have been a peer dependency.

## [6.0.0] - 2021-04-08

### Changed

- **BREAKING:** Set minimum Node.js version to `^12.0.0` ([#144](https://github.com/MetaMask/eslint-config/pull/144))
- Publish this config as its own package ([#141](https://github.com/MetaMask/eslint-config/pull/141))
  - The contents of this package were previously published as part of [`@metamask/eslint-config`](https://npmjs.com/package/@metamask/eslint-config).
    For changes prior to version `6.0.0`, please refer to the changelog of that package.
  - To continue extending this config, install this package and update your `.eslintrc.js` `extends` array to include `@metamask/eslint-config-nodejs` instead of `@metamask/eslint-config/nodejs`.
- Update `eslint` and other ESLint peer dependencies ([#151](https://github.com/MetaMask/eslint-config/pull/151))
