Last 4 releases share the same code from 8 months ago. No longer open source?

Where are the new features coming from since this repo has not been updated in 8 months?

How can we verify the code in the repo is what is running inside the packaged released?

How have new features been implemented such as flux without any changes to the application source code?

Is this app now considered closed source? Does the app load remote resources?

Please advise.
