Developer edition was designed for developers to get access to a minimal set of functions in Realm Platform they could use in development and in the early stages of the apps release.  After careful consideration and a great amount of feedback from our users we will no longer develop, maintain, or release the Realm Platform Developer Edition.  The good news is we now have a free trial version of Realm Platform in the cloud that has all the core features with no limitations on functionality. Additionally, we will have an extended trial period for developers to use and develop with Realm Platform Self-Hosted, again with no limits on functionality.  To get started with either of these, visit here.
