+We are currently in a phase of heavy development, and our team is actively working on various aspects of the framework to enhance its modularity and overall functionality. We understand the anticipation for a new release and assure you that we are working diligently towards it. While we have yet to set an exact release date to share, we are targeting a release in early October 2023. We believe that the improvements we are making will be well worth the wait.
