We are testing the upgrade and the first installation of nethserver-ejabberd & ejabberd-21.04
yum install http://packages.nethserver.org/nethserver/7.9.2009/autobuild/x86_64/Packages/nethserver-ejabberd-1.8.4-1.2.pr41.ge6451c3.ns7.noarch.rpm --enablerepo=nethserver-testing
It seems this time there is no breaking changes, Do I should bet money today ?
as usual test all feature you use, you want, check log in /var/log/ejabberd/ejabberd.log
