New features
-
Added JVM debug configuration support: The Hazelcast CR now supports configuring JVM remote debugging for Hazelcast members, including the debug port and suspend behavior, making it possible to attach a JVM debugger to a running cluster for troubleshooting.
-
Added IPv6 support for Kubernetes clusters: The Hazelcast CR now allows enabling IPv6, and the Operator automatically applies all configuration required to run a Hazelcast cluster on IPv6-based Kubernetes clusters.
-
Made the client port configurable: The port that Hazelcast clients use to connect to the cluster can now be configured in the Hazelcast CR, providing more flexibility in cluster network configuration.
Enhancements
-
Added support for multiple buckets for user code deployment: Users can now configure multiple remote storage buckets, each with its own secret, when downloading user code files, instead of being limited to a single bucket.
Fixes
-
Fixed updating Jet jobs created from a snapshot: Resolved an issue where a
JetJobcreated from a named snapshot could not be updated because theinitialSnapshotResourceNamefield could not be cleared. Jet jobs with theEXACTLY_ONCEprocessing guarantee can now be restarted without an initial named snapshot resource. -
Fixed Management Center not applying clientSecret updates: Resolved an issue where Management Center continued connecting to the cluster with outdated credentials after the content of the
clientSecretNamewas updated. The Operator now watches the Secrets referenced by theManagementCenterresource and appliesclientSecretupdates automatically.
