Jet engine lives on in Hazelcast 5.x

At Hazelcast we have a policy of supporting a minor version for two years since the initial release. For Hazelcast Jet 4.5 this period expired at the end of April, marking an end of Hazelcast Jet as a standalone product.

Since 2021 our Jet engine, a stream processing system that can do stateful computations over massive amounts of data with consistent low latency, has been part of Hazelcast Platform 5.x.

We encourage every Hazelcast Jet user still using any of the Jet 4.x versions to upgrade to Hazelcast 5.x. There are some minor incompatibilities in how a Hazelcast instance is started, but e.g. the Pipeline API is fully backward compatible. See the upgrade documentation for details.
