***** WARNING *****
|
||
|
|
|
||
|
|
We are renaming the rabbitmq server's nodename from '$CURRENT' to
|
||
|
|
'zulip@localhost', as rabbitmq is being reconfigured to listen only on
|
||
|
|
localhost. This will also make the server more resilient to hostname
|
||
|
|
changes. This will only affect you if you were using the rabbitmq
|
||
|
|
server for other, non-Zulip uses.
