### Core Server
|
|
|
|
#### Bug Fixes
|
|
|
|
* Disk space monitor now correctly parses output on (at least some) systems where non-ASCII characters are used in paths.
|
|
|
|
GitHub issue: [#3970](https://github.com/rabbitmq/rabbitmq-server/pull/3970)

GitHub issue: [#3967](https://github.com/rabbitmq/rabbitmq-server/pull/3967)
|
|
|
|
#### Enhancements
|
|
|
|
* Queue and binding [definition import](https://rabbitmq.com/definitions.html) can be delayed until a moment
|
|
when at least N nodes (e.g. three) have joined the cluster. This way imported quorum queues will have a desired
|
|
number of replicas from the start.
