v5.0.25

Enhancements

• #10568 Add shutdown counter information to emqx ctl listeners command

• #10571 Do not emit useless crash report when EMQX stops. Previously, when EMQX (and emqx_topic_metrics in particular) stopped and removed underlying tables, some messages were still being handled and crashed.

• #10588 Increase the time precision of trace logs from second to microsecond. For example, change from 2023-05-02T08:43:50+00:00 to 2023-05-02T08:43:50.237945+00:00.

• #10623 Renamed max_message_queue_len to max_mailbox_size in the force_shutdown configuration. Old name is kept as an alias, so this change is backward compatible.

• #10417 Improve get config performance by eliminating temporary references.

• #10525 Reduce resource usage per MQTT packet handling.

• #10528 Reduce memory footprint in hot code path.

• #10573 Improved performance of Webhook bridge when using synchronous query mode. This also should improve the performance of other bridges when they are configured with no batching.

• #10591 Improve the configuration of the limiter.

• Simplify the memory representation of the limiter configuration.

• Make sure the node-level limiter can really work when the listener's limiter configuration is omitted.

• #10625 Simplify limiter configuration.

• Reduce the complexity of the limiter's configuration. e.g. now users can use limiter.messages_rate = 1000/s to quickly set the node-level limit for the message publish.
• Update the configs/limiter API to suit this refactor.

Bug Fixes

• #10548 Fixed a race condition in the HTTP driver that would result in an error rather than a retry of the request. Related fix in the driver: https://github.com/emqx/ehttpc/pull/45

• #10556 Wrap potentially sensitive data in emqx_connector_http if Authorization headers are being passed at initialization.

• #10659 Fix the issue where emqx cannot start when sysmon.os.mem_check_interval is disabled.
