Important Changes
gen_rpc
library to version 3.4.1, which includes a node crash issue.Previously, if a node is force shutdown down while RPC channels are being established, it may cause a cluster peer node to crash.
Enhancements
Core MQTT Functionalities
#13525 Added new configuration item
shared_subscription_initial_sticky_pick
to specify the strategy for making the initial pick whenshared_subscription_strategy
is set tosticky
.#13942 The HTTP client now automatically reconnects if no activity is detected for 10 seconds after the latest request has expired.
Previously, it would wait indefinitely for a server response, causing timeouts if the server dropped requests.
This change impacts below components.
Authentication and Authorization
#13863 EMQX now supports
${cert_common_name}
placeholder in topic name templates for raw ACL rules.#13792 The banned-clients API
GET /banned
supports querying the rules using filters in the query string.The available filters are:
When adding a new banned client entry, the default expiration time for entries without the
until
parameter specified has been changed from 1 year toinfinite
.Rule Engine
#13773 Disabled rule actions now do not trigger
out_of_service
warnings.Previously, if an action is disabled, there would be a warning log with
msg: out_of_service
,and the
actions.failed
counter was incremented for the rule.After this enhancement, disabled action will result in a
debug
level log withmsg: discarded
,and the newly introduced counter
actions.discarded
will be incremented.MQTT over QUIC
#13814 Connection Scope Keepalive for MQTT over QUIC Multi-Stream:
This update introduces a new feature to maintain MQTT connections over QUIC multi-streams, even when the control stream is idle but other data streams are active.
Previously, clients had to send
MQTT.PINGREQ
on idle control streams to keep the connection alive. Now, a shared state is maintained for each connection, monitoring activity across all streams. This shared state helps determine if the connection is still active, reducing the risk of keepalive timeouts caused by Head-of-Line (HOL) blocking and improving overall connection stability.Bug Fixes
Core MQTT Functions
#13702 Clean up the corresponding exclusive subscriptions when a node goes down.
#13708 Fixed an issue which may cause shared subscription 'sticky' strategy to degrade to 'random'.
#13733 Made
cacertfile
optional when configuring https listener fromemqx ctl conf load
command.#13742 Fixed when subscribing with
+
as the first level, or#
as a wildcard, retained messages with topics starting with$
are incorrectly received.#13754 Fixed an issue when websocket connection would break consistently on its own.
#13756 Introduced more randomness to broker assigned client IDs.
#13790 The default heartbeat interval for the MQTT connector has been reduced from 300 seconds to 160 seconds.
This change helps maintain the underlying TCP connection by preventing timeouts due to the idle limits
imposed by load balancers or firewalls, which typically range from 3 to 5 minutes depending on the cloud provider.
#13832 Fixed that the
Publish
endpoint would have a 500 error when persistent session were enabled.#13842 Fixed a UTF-8 string validation exception.
