## [9.0.1](https://github.com/uuidjs/uuid/compare/v9.0.0...v9.0.1) (2023-09-12)

### build

- Fix CI to work with Node.js 20.x

## [9.0.0](https://github.com/uuidjs/uuid/compare/v8.3.2...v9.0.0) (2022-09-05)

### ⚠ BREAKING CHANGES

- Drop Node.js 10.x support. This library always aims at supporting one EOLed LTS release which by this time now is 12.x which has reached EOL 30 Apr 2022.

- Remove the minified UMD build from the package.

  Minified code is hard to audit and since this is a widely used library it seems more appropriate nowadays to optimize for auditability than to ship a legacy module format that, at best, serves educational purposes nowadays.

  For production browser use cases, users should be using a bundler. For educational purposes, today's online sandboxes like replit.com offer convenient ways to load npm modules, so the use case for UMD through repos like UNPKG or jsDelivr has largely vanished.

- Drop IE 11 and Safari 10 support. Drop support for browsers that don't correctly implement const/let and default arguments, and no longer transpile the browser build to ES2015.

  This also removes the fallback on msCrypto instead of the crypto API.

  Browser tests are run in the first supported version of each supported browser and in the latest (as of this commit) version available on Browserstack.

## [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.
