MDL MuseScore 4 release date?

Hello all,
this is my first time posting on the forums so I hope that this is the correct place to be posting this type of content. I have absolutely loved the quality and playback of MuseScore 4, and have been blown away by the realism and all of the new features. However, I also happen to write drumline music for marching band. I thoroughly enjoyed the fantastic playback of MDL for MuseScore 3, but it appears it is not available for MuseScore 4 quite yet. I've seen that apparently a new, and even somehow better version is being developed for MuseScore 4. I am very excited for this development. However, does anyone know (roughly) when this new extension should become available? Thank you all.
