Joomla 4 (incredible) support ACY mailing?

Hi I wonder if ACY mailing now is compatible with released stable Joomla 4 (incredible) ?

Yes, AcyMailing is compatible with Joomla 4

Is the version Essential 5.xx also compatible or we have to upgrade to Ver 7.5.11

Version 5 is not compatible with Joomla 4, and we won't make it compatible

We believe that this is not necessary when we have better version which is compatible
