In 2016, Janrain will rewrite its Android SDK. We are evaluating what this implementation will include, but we will focus on making the SDK more developer-friendly and simplifying the integration process. We will share more details as we finalize plans in the coming months.
With a new SDK on the horizon, the 6.0.0 release will include only critical updates to maintain compatibility with API levels 17-23. All feature requests will be prioritized as part of the development for the new SDK.
