##### ⚠ 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.
