For help installing and running Operator, see Install Operator and deploy a Hazelcast cluster.

New features

  • Added support for multiple user code sources: User Code Namespaces can now download JAR files from multiple buckets, URLs, and ConfigMaps, allowing user code to be assembled from multiple sources instead of being limited to a single source configuration.

Enhancements

  • Improved Jet job failure reporting: Enhanced JetJob failure handling to provide clearer error information when job submission or execution fails, making it easier to identify and troubleshoot the cause of a failure.

Fixes

  • Fixed unnecessary TLS configuration updates: Keystore and truststore files are now updated only when the content of the referenced Secret changes, preventing unnecessary TLS configuration updates when the Secret itself has not changed.
