The Kunena team has announce the arrival of Kunena 6.1.0 [K 6.1.0] which is now available for download as a native Joomla extension for J! 4.3.x & J! 4.2.x. This version addresses most of the issues that were discovered in K 6.0 and issues discovered during the development stages of K 6.0
Category / Global permissions no longer seem to be respected. I have category moderators who can now ban other members. this did not used to be the case. it used to be that only global moderators had ban permissions.
OK this seems to be related to EasySocial integration. If "moderators" are enabled in EasySocial then this seems to activate admin permissions. (this should not be the case since they do two different things)
Moderators can get to the Kunena profile via the Moderate button. And then clicking the username. This surprised me but seems to be more on the ES end a problem than Kunena.
