## [8.0.0](https://github.com/uuidjs/uuid/compare/v7.0.3...v8.0.0) (2020-04-29)

### ⚠ 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();
  ```

## [7.0.0](https://github.com/uuidjs/uuid/compare/v3.4.0...v7.0.0) (2020-02-24)

### ⚠ 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<4.x
- Convert code base to ECMAScript Modules (ESM) and release CommonJS build for node and ESM build for browser bundlers.
