Kafka 4.0.0 Release Announcement</a>
+ </h2>
+ 17 March 2025 - David Jacot
+
+ <p>
+ We are proud to announce the release of Apache Kafka®
4.0 This release contains many new
+ features and improvements. This blog post will highlight
some of the more prominent features.
+ For a full list of changes, be sure to check the <a
href="https://archive.apache.org/dist/kafka/4.0.0/RELEASE_NOTES.html";>release
notes</a>.
+ </p>
+ <p>
+ See the <a
href="https://kafka.apache.org/documentation.html#upgrade_4_0_0";>Upgrading to
4.0 from any versions 0.8.x through 3.9.x</a> section in the
+ documentation for the list of notable changes and detailed
upgrade steps.
+ </p>
+ <p>
+ Apache Kafka 4.0 is a significant milestone, marking the
first major release to operate entirely
+ without Apache ZooKeeper®. By running in KRaft mode
by default, Kafka simplifies
+ deployment and management, eliminating the complexity of
maintaining a separate ZooKeeper
+ ensemble. This change significantly reduces operational
overhead, enhances scalability, and
+ streamlines administrative tasks. We want to take this as
an opportunity to express our gratitude
+ to the ZooKeeper community and say, thank you! ZooKeeper
was the backbone of Kafka for
+ more than 10 years, and it did serve Kafka very well.
Kafka would most likely not be what it is
+ today without it. We don’t take this for granted and
highly appreciate all the hard work the
+ community invested to build ZooKeeper. Thank you!
+ </p>
+ <p>
+ Kafka 4.0 also brings the general availability of <a
href="https://cwiki.apache.org/confluence/x/HhD1D";>KIP-848</a> introducing a
powerful new consumer
+ group protocol designed to dramatically improve rebalance
performance. This optimization
+ significantly reduces downtime and latency, enhancing the
reliability and responsiveness of
+ consumer groups, especially in large-scale deployments.
+ </p>
+ <p>
+ Additionally, we are excited to offer <a
href="https://cwiki.apache.org/confluence/x/i4ogF";>early access</a> to
+ Queues for Kafka (<a
href="https://cwiki.apache.org/confluence/x/4hA0Dw";>KIP-932</a>), enabling
Kafka to support traditional queue semantics directly. This
+ feature extends Kafka’s versatility, making it an ideal
messaging platform for a wider range of
+ use cases, particularly those requiring point-to-point
messaging patterns.
+ </p>
+ <p>
+ These highlights illustrate Kafka's continued evolution to
meet the demands of modern,
+ scalable, and efficient data streaming and messaging
architectures.
+ </p>
Review Comment:
I think we should have a paragraph where we mention that major releases like
4.0 remove apis deprecated at least 12 months ago and then mention a few of the
highlights: minimum Java version bumps, minimum client/broker version support
(KIP-896) and perhaps minimum version to upgrade from. Details are already
mentioned later in the document, so I think it's ok to keep this paragraph
brief. But it's important enough that I think the brief version is needed in
this section.
