Dear Hazelcast community,
We are aware of an issue with an internal build, which is being prepared as 5.3.3. This is currently in testing, and due to an error in tooling, a 5.3.4 release has been published to the Maven Central repository.
Please DO NOT use the 5.3.4 build - as this was incomplete and was created in error. We'll look to rectify the issue as soon as possible this week and look out for a 5.3.5 release, which we'll put out shortly to resolve the issue.
Thank you on behalf of the Hazelcast Engineering team.
