-The SDK no longer ships with internal implementations for the `Map` and `Set` global objects, which were used to support old browsers.
 If you need to target environments that do not support these features natively, you should provide a polyfill for them. For example, [es6-map](https://github.com/medikoo/es6-map) for `Map`, and [es6-set](https://github.com/medikoo/es6-set) for `Set`.
 
 - **Dropped support for Split Proxy below version 5.9.0, when using in the browser (client-side API). The SDK now requires Split Proxy 5.9.0 or above.**
