JEM 4.0 Soon available?

What is the status for JEM 4.0?
I installed JEM 2.3.6 and now I get this warning message:
Warning!
JEM 4 for Joomla 4 is now available. For update instructions, please visit the JEM help section.

The help section describes how to prepare JEM 2.3.6 for JEM 4.0, make a backup and then migrate Joomla to 4.0. Continued written: install JEM 4.0.
But when I visit the download section, I only find JEM 2.3.6

(I know there is a BETA version, but I'm waiting for the stable version).
(I also did a lot of work on translations for 4.0 into Dutch).

August is coming very soon?
Don't get me wrong: I'm not asking for the stable version NOW, but a prediction of when it will be released would be most welcome.

Thank you for your asking and your translations. It's a big help! As a betatester knowing well the working part of JEM, I can say the actual version is working well or at least as well as JEM in Joomla 3. And there are some new features which make it better. It is in my own responsibility, that I use it just now on livesites.
In my eyes our devs can't finish to make it better and better, because they fear to get too many posts when releasing. But each born child makes new problems beneath the joy! I hope your asking will encourage them!

There is no link to download the latest beta version JEM 40b4 released on 2023-05-23 !

go to git to the branch JEM for Joomla 4. You'll find the zip in the code part.

I download this .zip file but when i install the component, i have this error :
Unable to detect manifest file
and installation failed

golfy is right.
When i search git / jemproject there is a link to:
JEM project
JEM for joomla 4-archive
JEM internal

In the JEM project there is JEM 2.3.6 (stable)
In the JEM for Joomla 4-archive you find JEM 4beta, released 2023-04-27
