### Release Notes

<details>
<summary>prettier/eslint-config-prettier</summary>

### [`v8.0.0`](https://togithub.com/prettier/eslint-config-prettier/blob/master/CHANGELOG.md#Version-800-2021-02-21)

[Compare Source](https://togithub.com/prettier/eslint-config-prettier/compare/v7.2.0...v8.0.0)

-   Changed: All configs have been merged into one!

    To upgrade, change:

    ```json
    {
      "extends": [
        "some-other-config-you-use",
        "prettier",
        "prettier/`@&#8203;typescript-eslint",`
        "prettier/babel",
        "prettier/flowtype",
        "prettier/react",
        "prettier/standard",
        "prettier/unicorn",
        "prettier/vue"
      ]
    }
    ```

    Into:

    <!-- prettier-ignore -->

    ```json
    {
      "extends": [
        "some-other-config-you-use",
        "prettier"
      ]
    }
    ```

    The `"prettier"` config now includes not just ESLint core rules, but also rules from all plugins. Much simpler!

    So … what’s the catch? Why haven’t we done this earlier? Turns out it’s just a sad mistake. I ([`@&#8203;lydell](https://togithub.com/lydell))` was confused when testing, and thought that turning off unknown rules in a config was an error. Thanks to Georgii Dolzhykov ([`@&#8203;thorn0](https://togithub.com/thorn0))` for pointing this out!

    (The ["prettier/prettier" config][prettier-prettier-config] still exists separately. It’s the odd one out. The main `"prettier"` config does _not_ include the rules from it.)

-   Changed: The CLI helper tool now only prints warnings for [arrow-body-style] and [prefer-arrow-callback], just like other “special rules.” This means that if you’ve decided to use those rules and [eslint-plugin-prettier] at the same time, you’ll get warnings but exit code zero (success).
