- We accordingly removed deprecated methods within
UsersRepositoryManagementMBean exposed over JMX (unsetAlias, getAlias,
unsetForwardAddress, getForwardAddress). RecipientRewriteTables should be used
instead.
### Third party softwares
+ - The distributed James server product (relying on Guice, Cassandra,
ElasticSearch, RabbitMQ and optionally Swift) now needs at least RabbitMQ 3.8.

+Concerned products: Guice distributed James (rabbitMQ)
+
+The distributed James project (relying on Guice, Cassandra, ElasticSearch,
RabbitMQ and optionally Swift) benefits from a new distributed task mananger.
+
+In order to enforce task sequential processing at the cluster level, we rely
on a single active consumer, which is a feature introduced in RabbitMQ 3.8.
+
+Users of distributed James product thus need to upgrade their RabbitMQ server
to be at least version 3.8.
