+Our monthly roundup of key activities and knowledge to keep the community
informed.
+
+== Release Notes
+
+=== Released
+
+We hit an important milestone on 1st May 2022. Although this Changelog looks
back at the previous month, we want to highlight this significant milestone for
the project. We have now hit our one-year branch and frozen the code for the
release of Apache Cassandra 4.1. Any further changes at this point will be bug
fixes before we announce General Availability (GA). Special thanks go to *Mick
Semb Wever* for all the work that has gone into the release process.
+
+*Note:* for this release cycle only, we will continue to support Cassandra 3.0
so there will be four supported versions - 3.0.latest, 3.11.latest, 4.0.latest
and 4.1.latest. See
xref:blog/Behind-the-scenes-of-an-Apache-Cassandra-Release.adoc[Behind the
Scenes of an Apache Cassandra Release] for more details.
+
+The latest release of Apache Cassandra is
https://www.apache.org/dyn/closer.lua/cassandra/4.0.3/apache-cassandra-4.0.3-bin.tar.gz[4.0.3^]
(https://downloads.apache.org/cassandra/4.0.3/apache-cassandra-4.0.3-bin.tar.gz.asc[pgp^],
https://downloads.apache.org/cassandra/4.0.3/apache-cassandra-4.0.3-bin.tar.gz.sha256[sha256^],
and
https://downloads.apache.org/cassandra/4.0.3/apache-cassandra-4.0.3-bin.tar.gz.sha512[sha512^]),
which has been available since 17 February 2022. As stated in the [...]
+
+As a result, we are advising 3.0 users to upgrade to 3.0.26; 3.11 users to
upgrade to 3.11.12; and 4.0 users should upgrade to 4.0.3.
+
+Please read the
https://gitbox.apache.org/repos/asf?p=cassandra.git;a=blob_plain;f=NEWS.txt;hb=refs/tags/cassandra-4.0.3[release
notes^] and https://issues.apache.org/jira/browse/CASSANDRA[let us know^] if
you encounter any problems.
+
+See the xref:download.adoc[download section] for the latest stable and older
supported versions of source and binary distributions.
+
+To stay up-to-date, we recommend joining the Cassandra
xref:community.adoc#discussions[mailing lists].
+
+== Community Notes
+
+_Updates on Cassandra Enhancement Proposals (CEPs), how to contribute, and
other community activities._
+
+_For newcomers to the project, we have a useful
xref:development/index.adoc[‘Contributing to Cassandra’] page for how to get
involved and get started._
+
+_We also recommend taking a look at two Jira ticket queries we’ve created. One
is a Kanban board for
https://issues.apache.org/jira/secure/RapidBoard.jspa?rapidView=496&quickFilter=2252[“Failing
Tests” tickets that are unassigned^] and the other corresponds to our
https://issues.apache.org/jira/secure/RapidBoard.jspa?rapidView=484&quickFilter=2162&quickFilter=2160[Low
Hanging Fruit or “Starter Tickets”^] for 4.0.x and 4.1.x. Feel free to
self-select a ticket to work on._
+
+_Any of these tickets should be of appropriate complexity for someone new to
the project to tackle. Just remember to assign yourself to the ticket and
acknowledge the status, such as ‘Work in Progress’ and ‘Needs Comitter/Patch
Available’ when you submit your patch. You can also reach out on the
https://the-asf.slack.com/[ASF Slack^] in the #cassandra-dev Slack channel. Use
@cassandra_mentors to contact our Cassandra mentors!_
+
+Read PMC member Josh McKenzie’s
https://lists.apache.org/thread/lnmw2b4hzkl977p9hxv1sbdfqlq5snc6[latest
bi-weekly update^] for ongoing discussions and the latest on ticket progress.
+
+=== Discussed
+
+As we mentioned, above, we forked Cassandra 4.1 and froze the branch on May 1.
The community has also agreed to block releases on green CI and are
https://butler.cassandra.apache.org/#/[cleaning up test failures^] before
release.
+
+=== Discussed
+
+The Apache Foundation in conjunction with the Apache Cassandra PMC will be
hosting a 2-day Cassandra track at
https://www.apachecon.com/acna2022/[ApacheCon North America^], which will take
place between October 3-6 at the Sheraton Hotel, New Orleans.
+
+:!figure-caption:
+
+.Apache Cassandra has a dedicated track at ApacheCon North America 2022 and
there’s an opportunity to contribute to the Performance Engineering track as
well, so get submitting!
+image::blog/ApacheCon2022banner.png[ApacheCon 2022]
+
+The CFP is open now and will run until May 23 for talks on the Cassandra
Track. Read the recent
xref:blog/ApacheCon-NA-2022-Call-for-Papers-Open.adoc[blog post] for more
details.
+
+If you have something you did on the project, something you're thinking about
doing, a fascinating use-case, or anything you think would be interesting to
your fellow Cassandra practitioners, please don't hesitate to submit a proposal
for it.
+
+=== Discussed
+
+ApacheCon North America will also include a Performance Engineering track for
the first time this year. This is an opportunity to share your Apache Cassandra
experiences, lessons learned, and innovations in this space. See the CFP
details
https://www.linkedin.com/pulse/call-papers-performance-engineering-track-apachecon-paul-brebner/[here^].
+
+=== Discussed
+
+There is a
https://lists.apache.org/thread/omoo3cvjcrwh5wvqb7ndjqzzhyp17klx[discussion^]
on the oldest version of Python 3.x to support with cqlsh and other scripts in
4.1. The discussion revolves around what version of Python is supported in
versions of CentOS and RHEL derivatives, and when that support expires.
+
+=== Discussed
+
+Based on
https://lists.apache.org/thread/fnlzos2v78xmgxhz37xsskpdc30dl95l[discussions^],
*Erick Ramirez* is developing
https://docs.google.com/document/d/1-ZYpl9tif9OAMdAxFLxA1mTPNp0zkNW4kzXvfvRBHUc/edit?usp=sharing[a
1-page guide^] to help users provide helpful details in their questions so
they can obtain the answers they need quickly from the community and save time.
+
+=== Discussed
+
+We continue to need more volunteers for the
https://lists.apache.org/thread/zhkc0190wvw168pygw186x4f88kcx9qw[Build Lead
role^]. As you might expect, there are more changes going into the trunk for
the new release, and this role has been instrumental in helping us map our
current CI situation. But, as *Mick Semb Wever* has indicated in the mailing
list thread, we haven’t achieved a green ASF infrastructure CI on trunk yet,
which is a key goal for the project. The build lead role has been [...]
+
+=== Discussed
+
+*Ekaterina Dimitrova*
https://lists.apache.org/thread/9lo1hccvf93828k9rf1hkr2176kcvx8h[confirmed
again^] some details around the new format and backward compatibility for data
storage, data rate and duration configuration parameters. Please reach out if
you have any questions or concerns.
+
+=== Discussed
+
+*David Capwell* has highlighted that some non-standard Java classes are
exposed via JMX, so that JMX will fail unless the JMX client also has
Cassandra's jars. A solution is being discussed
https://lists.apache.org/thread/j7v75sxncm05dgc2wch84lkkh224lyz7[here^].
+
+=== Announced
+
+Canonical has
https://containerjournal.com/features/canonical-expands-ubuntu-container-image-portfolio/[added
Apache Cassandra container images^] to its Long Term Support (LTS) Docker
Image Portfolio which is accessed via DockerHub. This is part of a curated set
of secure container application images that it will support for 10 years. As
part of that commitment, Canonical will fix any critical security issues with
the images within 24 hours.
+
+=== Announced
+
+Quine, an open source streaming graph framework, which was announced in April,
https://venturebeat.com/2022/04/27/streaming-graph-analytics-thatdots-open-source-framework-quine-is-gaining-interest/[supports
Apache Cassandra^] which it uses as the underlying storage component for
combining incoming data in real-time with historical data.

+[quote,'https://www.bloomberg.com/company/stories/meet-the-team-indices-engineering/[Noel
Gunasekar^]']
+____
+Our group is working on a multi-year build, creating a new Index Construction
Platform to handle the daily production of the Bloomberg Barclays fixed income
indices. This involves building and productionizing an Apache Solr-backed
search platform to handle thousands of searches per minute, an Apache Cassandra
back-end database to store millions of data points per day, and a distributed
computational engine to handle millions of computations daily.
