Will the version 3.xx still be working after "retired" date or I have to migrate it to version 4.xx to make it working ?
Hi @MuhammadAlza, that article is specific to the Web Optimizer, which will be retired in July 2022.
However, we do recommend migrating to 4x sooner rather than later, as the majority of the development work occurs there.
Hi @MuhammadAlza, I'm not sure what you mean by the "widget".
For the Web Optimizer, you can no longer use it to create custom builds, but existing custom builds will continue to be hosted until July 2022.
