### [`v8.0.0`](https://togithub.com/uuidjs/uuid/blob/master/CHANGELOG.md#&#8203;800-httpsgithubcomuuidjsuuidcomparev703v800-2020-04-29)

[Compare Source](https://togithub.com/uuidjs/uuid/compare/v7.0.3...v8.0.0)

##### ⚠ BREAKING CHANGES

-   For native ECMAScript Module (ESM) usage in Node.js only named exports are exposed, there is no more default export.

    ```diff
    -import uuid from 'uuid';
    -console.log(uuid.v4()); // -> 'cd6c3b08-0adc-4f4b-a6ef-36087a1c9869'
    +import { v4 as uuidv4 } from 'uuid';
    +uuidv4(); // ⇨ '9b1deb4d-3b7d-4bad-9bdd-2b0d7b3dcb6d'
    ```

-   Deep requiring specific algorithms of this library like `require('uuid/v4')`, which has been deprecated in `uuid@7`, is no longer supported.

    Instead use the named exports that this module exports.

    For ECMAScript Modules (ESM):

    ```diff
    -import uuidv4 from 'uuid/v4';
    +import { v4 as uuidv4 } from 'uuid';
    uuidv4();
    ```

    For CommonJS:

    ```diff
    -const uuidv4 = require('uuid/v4');
    +const { v4: uuidv4 } = require('uuid');
    uuidv4();
    ```

##### ⚠ BREAKING CHANGES

-   The default export, which used to be the v4() method
    but which was already discouraged in v3.x of this library, has been
    removed.
-   Explicitly note that deep imports of the different uuid
    version functions are deprecated and no longer encouraged and that
    ECMAScript module named imports should be used instead.
    Emit a deprecation warning for people who deep-require the different
    algorithm variants.
-   Remove builtin support for insecure random number
    generators in the browser. Users who want that will have to supply their
    own random number generator function.
-   Remove support for generating v3 and v5 UUIDs in
    Node.js&lt;4.x
-   Convert code base to ECMAScript Modules (ESM) and
    release CommonJS build for node and ESM build for browser bundlers.
