v5.0.20

Enhancements

• #10059 Errors returned by rule engine API are formatted in a more human readable way rather than dumping the raw error including the stacktrace.

Bug Fixes

• #10032 When resources on some nodes in the cluster are still in the 'initializing/connecting' state, the bridges/ API will crash due to missing Metrics information for those resources. This fix will ignore resources that do not have Metrics information.

• #10044 Fix node information formatter for stopped nodes in the cluster. The bug was introduced by v5.0.18.

• #10054 Fix the problem that the obfuscated password is used when using the /bridges_probe API to test the connection in Data-Bridge.

• #10058 Deprecate unused QUIC TLS options. Only following TLS options are kept for the QUIC listeners:

  • cacertfile
  • certfile
  • keyfile
  • verify

• #10076 Fix webhook bridge error handling: connection timeout should be a retriable error. Prior to this fix, connection timeout was classified as unrecoverable error and led to request being dropped.

• #10078 Fix an issue that invalid QUIC listener setting could casue segfault.

• #10084 Fix problem when joining core nodes running different EMQX versions into a cluster.
