= 5.5.3 Release Notes | ||
:description: These release notes list any new features, enhancements, fixes, and breaking changes implemented between version 5.5.2 and version 5.5.3 of Hazelcast Platform. | ||
|
||
{description} | ||
|
||
**Release date**: 2025-02-12 | ||
|
||
This is a maintenance release for {enterprise-product-name}. | ||
|
||
For help downloading Hazelcast {enterprise-product-name}, see xref:getting-started:install-enterprise.adoc[] or https://hazelcast.com/trial-request/?utm_source=docs-website[request a trial license key]. | ||
|
||
== Enhancements | ||
* **Added IPv6 support to the AWS discovery plugin**: The AWS discovery plugin now supports IPv6 by checking for an `ipv6address`` field in the instance description and adding an extra entry for private-to-public mapping as (`ipv6address`, `ipv6address`). If the client is inside AWS, it will prioritize using the private IPv6, which ensures better connectivity in IPv6-enabled environments. | ||
* **Updated BouncyCastle to support FIPS compliance**: Hazelcast now supports FIPS-compliant mode with an updated BouncyCastle implementation. Previously, a public key used by Hazelcast was not endorsed in FIPS-approved mode under BouncyCastle version 2.0.0. | ||
* **Enhanced error message received by clients using FencedLock**: During a CP Subsystem reset, clients using FencedLock previously received a `NotLeaderException` stating “null is not LEADER of null. Known leader is: N/A". This message now reads "Lock[<lock-name>] is no longer valid in the CP group [<group-id>] as the cluster has no information about Lock[<lock-name>]. Please recreate the lock or rejoin the cluster to obtain a valid reference." | ||
|
||
For more details on new features, see xref:ROOT:whats-new.adoc[What's new in 5.5]. | ||
|
||
== Security | ||
* **Security Fix for CVE-2023-45676**: We have resolved https://github.com/advisories/GHSA-gcg6-xv4f-f749[CVE-2023-45676], a dependency vulnerability related to improper authorization checks in certain scenarios. This issue could potentially allow attackers to bypass expected permission restrictions. | ||
|
||
== Fixes | ||
* **Fixed task config publishing in Kafka Connect**: Fixed an issue in `LateJoiningListener` where a race condition in `ringbuffer.tailSequence()` could result in a missed message if a message was published between two calls to `tailSequence()`. Also resolved a race condition where a message could be processed before `sourceConnector` and `taskRunner` were fully initialized, causing a hidden NullPointerException (NPE). The listener is now registered only after these fields are set and additional logging is added for exceptions in `processMessage` to help identify issues like the hidden NPE. | ||
* **Fixed migration issues with UCN classes in `InMemoryFormat.OBJECT`**: Fixed an issue where inserting an entry with classes from User Code Namespace (UCN) into an IMap and other data structures configured with `InMemoryFormat.OBJECT` resulted in migration failures. | ||
|
||
== Known issues | ||
* There is currently a known issue that has potential for causing a memory leak in Vector collections in some scenarios. For more information, including a workaround, see xref:data-structures:vector-collections.adoc#known-issue[Vector Collection Known Issue]. |
