) to be enabled before upgrading,there is no upgrade path from 3.12.14 (or a later patch release) straight to
4.0.0
.Required Feature Flags
This release does not graduate any feature flags.
However, all users are highly encouraged to enable all feature flags before upgrading to this release from
3.13.x.

RabbitMQ 4.0.0 nodes can run alongside
3.13.x

-specific features can only be made available when all nodes in the clusterupgrade to 4.0.0 or a later patch release in the new series.
While operating in mixed version mode, some aspects of the system may not behave as expected. The list of known behavior changes will be covered in future updates.
Once all nodes are upgraded to 4.0.0, these irregularities will go away.
