Changes since e5.1.1-alpha.1

Enhancements

• #11249 Support HTTP API for setting alarm watermark of license.

• #11251 Add /cluster/topology HTTP API endpoint

GET request to the endpoint returns the cluster topology: connections between RLOG core and replicant nodes.

• #11253 The Webhook/HTTP bridge has been refactored to its own Erlang application. This allows for more flexibility in the future, and also allows for the bridge to be run as a standalone application.

• #11241 Schema Registry has been refactored to its own Erlang application. This allows for more flexibility in the future.

• #11236 Improve the speed of clients querying in HTTP API /clients endpoint with default parameters

Bug Fixes

• #11250 Fix while a WebSocket packet contains more than one MQTT packet, the order of MQTT packets will be reversed.

• #11271 Ensure that the range of percentage type is from 0% to 100%.

• #11272 Fix a typo in the log, when EMQX received an abnormal PUBREL packet, the pubrel was mistakenly typo as pubrec.

• #11281 Restored support for the special $queue/ shared subscription.

• #11242 Restart emqx_ee_schema_registry when a node joins a cluster.

As emqx_ee_schema_registry uses Mria tables, a node joining a cluster needs to restart this application in order to start relevant Mria shard processes. This is needed to ensure a correct behaviour in Core/Replicant mode.

• #11266 Fix and improve support for TDEngine insert syntax.

• Support inserting into multi-table in the template

For example:

insert into table_1 values (${ts}, '${id}', '${topic}') table_2 values (${ts}, '${id}', '${topic}')

1. Support mixing prefixes/suffixes and placeholders in the template

For example:

insert into table_${topic} values (${ts}, '${id}', '${topic}')

Note: This is a breaking change. Previously the values of string type were quoted automatically, but now they must be quoted explicitly.

For example:

insert into table values (${ts}, '${a_string}')
