Release Highlights


  • If rabbitmqctl can't contact a node, suggest to verify any Erlang TLS distribution configuration (#162).
Bug fixes
  • Ensure the memory monitor is fully started before the file handle cache is used (since 3.5.2, #157). Before, the problem could lead to the following crash during RabbitMQ startup:

    =CRASH REPORT==== ... ===
      initial call: gen:init_it/6
      pid: <0.229.0>
      registered_name: []
      exception exit: {noproc,
        in function  gen_server2:terminate/3

  • Deprecate com.rabbitmq.client.Channel methods related to the old flow control (rabbitmq/rabbitmq-java-client#59):

    boolean flowBlocked();
    void addFlowListener(FlowListener listener);
    boolean removeFlowListener(FlowListener listener);
    void clearFlowListeners();

Building and packaging

Bug fixes
  • When updating Git remote URLs, use git set-url ... to set the fetch URL, not git set-url --fetch ... (since 3.5.1).
