Bug Fixes
-
Avoid seeding default user in old clusters that still use the deprecated
management.load_definitions
option.
This could result in an extra user,guest
or under an overriden default user name, to appear
in addition to the user accounts imported from definitions.Note that the default user with well-known name can only connect from
localhost
by default, so
this would not expose reasonably configured production nodes to remote connections.GitHub issue: #4904
-
Streams could run into an exception or fetch stale stream position data in some scenarios.
GitHub issue: #4898
-
rabbitmqctl set_log_level
