5.2.4 Release Notes

Updated the version of jackson-core dependency to 2.15.2. #24730

Hazelcast was sending requests to Kubernetes API when deploying an application with embedded Hazelcast and service-dns (DNS lookup mode) specified to a Kubernetes cluster. This was causing the requests to be unsuccessful and the application not to start. This mechanism has been improved by creating Kubernetes client only for the DNS lookup mode. #24045

Fixed an issue where a member with persistence can be restarted even though the persistence file structure is not valid (e.g., the persistence directory does not contain the required files). #5876

Fixed an issue where some of the members in a Hazelcast cluster deployed on Kubernetes (as a statefulset) shut down with an exception in a delayed manner. #24709

Fixed an issue where Jet job snapshots could be prematurely deleted after a restart of a cluster, having lossless restart enabled. #24576

Fixed an issue where the SELECT COUNT(DISTINCT COLUMN) query for maps was producing incorrect results. #24490

Fixed various issues in Health Monitor including incorrect metric names. #24634

Fixed an issue where the REST calls were failing for Hazelcast clusters with TLS v1.3 configured, and deployed on Kubernetes. #24624

Fixed an issue where SQL statements were failing when a class (to determine the fields of a key/value pair) no longer exists but the mapping is still valid. #24043

Fixed an issue where lastAccessTime and expirationTime was not updated when an entry is accessed via executeOnEntries. #24012
