that 1.3 was released on 29 July. This version supports Apache Cassandra 4.0

+<p>Two major features for K8ssandra are in development for release at KubeCon
North America: Remote restore and multi-cluster Kubernetes deployment
support.</p>
+</div>
+<div class="paragraph">
+<p>Jeff also explained that K8ssandra is being refactored, as part of the
roadmap to 2.0, to provide a higher-level K8ssandra operator designed to be
layered on top of a simple Helm install experience and provide greater control
over cass-operator, Medusa, Reaper, and K8ssandra itself. The initial design of
this document is available <a
href="https://github.com/k8ssandra/k8ssandra/blob/main/technical-docs/K8SSANDRA-OPERATOR-DESIGN.md";
target="_blank" rel="noopener">here</a>.</p>
+</div>
+<div class="paragraph">
+<p>Refactoring and API upgrade work also continues on the cass-operator, while
Franck Dehay also detailed the upgrade of <a
href="https://github.com/Orange-OpenSource/casskop"; target="_blank"
rel="noopener">CassKop</a> to version 2.0. The main feature of v2.0 is support
for Cassandra 4.0.</p>
+</div>
+<div class="paragraph">
+<p>CassKop 2.0 uses cass-config builder easing users from configuring
Cassandra to K8ssandra by using the configuration changes in the CRD. Using
cass-config also means CassKop supports Apache Cassandra 3.0 and 4.0 more
easily.</p>

-<p>On November 9th, 2015 the Apache Cassandra project released version 3.0
and, with it, a host of really big changes you would expect in a major version.
Over the past six years, there have been releases inside the 3.x branch but
never a major version release. <a href="../download.html" class="page">Today we
feel a lot of pride in our community with the release of Cassandra 4.0</a>. It
has been a long time coming, but we hope you will see it was worth the wait.</p>
+<p>We are advising users of Apache Cassandra 3.023, 3.0.24, 3.11.9 and 3.11.10
to upgrade, because of the potential for data corruption during schema changes,
details are below:</p>
</div>
<div class="paragraph">
-<p>Six years is a long time between major releases and many in our community
have asked why it has taken so long. The shortest and easiest answer is that
the project decided to become uncompromising on one important feature: quality.
As the project was gaining traction in the early years, there was an
unfortunate general rule about Cassandra: Wait until the x.6 version or six
months before upgrading your production clusters to a new version. Software
projects have already had the user ru [...]
+<p>The bug reported in <a
href="https://issues.apache.org/jira/browse/CASSANDRA-16735"; target="_blank"
rel="noopener">CASSANDRA-16735</a> was known to cause corruption thought to be
recoverable but can, in fact, induce <strong>non-recoverable</strong>
corruption in some partitions. If you are not yet on 3.0.23, 3.0.24, 3.11.9, or
3.11.10, it is recommended, now that the Cassandra community has released
3.0.25 and 3.11.11, to skip directly from 3.0.22 to 3.0.25 or from 3.11.8 to
3.11.11. [...]
</div>
<div class="paragraph">
-<p>To get the quality required, we took a completely different approach to
verify data correctness in Cassandra. The scale that Cassandra clusters can
reach means that there is an enormous surface area for potential bugs or data
corruption, so we purpose-built new tools to cover every requirement.</p>
+<p>While the issue has been known for some time, the severity of the issue was
not well understood. This understanding has improved and with that we are
suggesting the above actions for all users.</p>
+</div>
+<div class="paragraph">
+<p>The issue was introduced by a fix for <a
href="https://issues.apache.org/jira/browse/CASSANDRA-15899"; target="_blank"
rel="noopener">CASSANDRA-15899</a> which affected all versions up to and
including 3.0.22 and 3.11.8. The fix for CASSANDRA-16735 was to revert the
patch made in CASSANDRA-15899 meaning clusters will continue to be susceptible
to this transient issue.</p>

susceptible to non-recoverable corruption and should be upgraded
immediately.</p>

applications running in the world today. From finance to healthcare and
everything in between, the data that is stored in Cassandra has to have the
