Joomla 6

Hello,
Is JEM preparing for Joomla 6?
Thanks in advance.

yes, we are. It works with compat plugin. For more, there are lot of things to do.

Hello,
When I try to install JEM on Joomla6, I only get the error message Cannot install JEM in this Joomla version.

Hi, that's true. Joomla 6 is pretty new. Our devs are volunteers and have beneath that a real life. So if you search in our forum here about Joomla 6 and JEM, you get an answer, what's going on and when JEM will be ready. If you are a dev you're invited to join the team.

at the moment:
"Before working on JEM support for Joomla 6, we should focus on finalizing JEM 4.4.0 with Joomla 5 support and closing as many issues and new features as possible. There’s a lot to do, few people, and limited time.I think we should take it step by step, without getting overloaded or losing control. For now, let’s focus on JEM 4.4.0 for Joomla 5. Once it’s out, we can move on.There are many issues to resolve (open), but right now I can focus on JEM 4.4.0 with the time I have. This is just my view.Feel free to go ahead with this. Once 4.4.0 is out, I’ll jump into that branch."
