+Our monthly roundup of key activities and knowledge to keep the community
informed.
+
+== Release Notes
+
+=== Released
+
+The latest release of Apache Cassandra is
https://www.apache.org/dyn/closer.lua/cassandra/4.0.5/apache-cassandra-4.0.5-bin.tar.gz[4.0.5^]
(https://downloads.apache.org/cassandra/4.0.5/apache-cassandra-4.0.5-bin.tar.gz.asc[pgp^],
https://downloads.apache.org/cassandra/4.0.5/apache-cassandra-4.0.5-bin.tar.gz.sha256[sha256^],
https://downloads.apache.org/cassandra/4.0.5/apache-cassandra-4.0.5-bin.tar.gz.sha512[sha512^]),
which we announced on 18 August 2022. Crucially, this release contains [...]
+
+While this is the Changelog highlight activities for July, we want to
acknowledge the CentOS 7 issue, which will be resolved in Apache Cassandra
4.0.6. This will soon be out and will re-add support for CentOS 7.
+
+Please read the
https://gitbox.apache.org/repos/asf?p=cassandra.git;a=blob_plain;f=NEWS.txt;hb=refs/tags/cassandra-4.0.5[4.0.5
release notes^] and let us know if you encounter any problems.
+
+Our focus remains on the tickets that block the beta release and release
candidate for Apache Cassandra 4.1. We have only a handful of unassigned
tickets left and these would be a great introduction for someone new to
contributing to the project (see details, below, on how to help).
+
+The other supported releases remain Apache Cassandra 3.11
(https://www.apache.org/dyn/closer.lua/cassandra/3.11.13/apache-cassandra-3.11.13-bin.tar.gz[3.11.13^],
https://downloads.apache.org/cassandra/3.11.13/apache-cassandra-3.11.13-bin.tar.gz.asc[pgp^],
https://downloads.apache.org/cassandra/3.11.13/apache-cassandra-3.11.13-bin.tar.gz.sha256[sha256^],

and 3.0 series (https://www.apache.o [...]
+
+Please read the release notes for
https://gitbox.apache.org/repos/asf?p=cassandra.git;a=blob_plain;f=NEWS.txt;hb=refs/tags/cassandra-3.11.13[3.11.13^]
and
https://gitbox.apache.org/repos/asf?p=cassandra.git;a=blob_plain;f=NEWS.txt;hb=refs/tags/cassandra-3.0.27[3.0.27^]
and let us know if you encounter any problems.
+
+*Note:* For this release cycle only, we will continue to support 3.0. as well
as the 3.11., 4.0., and 4.1 latest patch versions. See
xref:blog/Behind-the-scenes-of-an-Apache-Cassandra-Release.adoc[Behind the
Scenes of an Apache Cassandra Release] for more details.
+
+See the xref:download.adoc[download section] for the latest stable and older
supported versions of source and binary distributions. Please make sure you
read the additional information on the Download page as the *Debian and RedHat
package repositories have moved*.
+
+To stay up-to-date, we recommend joining the
xref:community.adoc#discussions[Cassandra 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 would also recommend reading the
link:/doc/latest/cassandra/architecture/overview.html[overview of the C*
architecture]._
+
+_If you’d like to help us get 4.1 over the line, check out the unassigned
tickets marked as
https://issues.apache.org/jira/secure/RapidBoard.jspa?rapidView=484&quickFilter=2454&quickFilter=2160[beta
blockers^]. These are great candidates for someone new to the project._
+
+_We also recommend viewing 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. We
have 13 mentors ready to help, and you can contact them by using
@cassandra_mentors._
+
+_You can also read PMC member *Josh McKenzie’s*
https://lists.apache.org/thread/3chthoxo4bjcx9b1bbzv4ptf766ns513[latest
bi-weekly update^] for ongoing discussions and the latest on ticket progress._
+
+=== Announced
+
+A huge thanks to everyone who worked on the Cassandra World Party this year,
whether they moderated, presented a talk, or helped behind the scenes. Thank
you also to the community for turning up and supporting the event! 🙏
+
+A final thank you goes to our sponsors this year,
https://axonops.com/[AxonOps^] and https://www.datastax.com/[DataStax^]!
+
+You can catch up with all the livestreams and talks from the three sessions
across three time zones by reading our

+
+=== Announced
+
+The Project Management Committee (PMC) is pleased to announce that *Jacek
Lewandowski* has been invited to become a committer, and he has accepted!
Thanks for all your contributions, Jacek! 👏
+
+=== Announced
+
+The community would also like to offer our appreciation to *Nate McCall*, who
https://lists.apache.org/thread/5l9xskv5k6q2fshw7oltwh6fz196pwk6[stepped down^]
from the PMC chair role in July. Thanks for all your many years of hard work,
Nate!👏
+
+The position of chair is an administrative position that interfaces with the
Apache Software Foundation Board, by submitting regular reports about project
status and health. Read more about the PMC chair role on Apache projects. For
anyone unaware of how ASF projects are run, you can learn more about PMCs and
the various roles by reading the
https://www.apache.org/foundation/how-it-works.html#pmc[ASF guide^].
+
+And the cycle continues with the announcement of Mick Semb Wever as the new
PMC chair and we wish him the best of luck in the role! 👍
+
+=== Announced
+
+The https://open.spotify.com/episode/1UwAaaKV2rzvkGNJO8PIiP[next episode of
The Apache Cassandra Corner^] podcast is available now. Host, *Aaron Ploetz*,
discovers what’s really happening when you turn on your smart TV by chatting to
Jeff Beck, Director at SmartThings. The conversation covers Apache Cassandra’s
role in powering your entertainment and Jeff’s experience of supporting
Cassandra at a global scale.
+
+=== Discussed
+
+As part of the implementation work for
https://cwiki.apache.org/confluence/x/FQRACw[CEP-15 General-Purpose
Transactions^], *Blake Eggleston* has been
https://lists.apache.org/thread/5sds3968mnnk42c24pvgwphg4qvo2xk0[drafting
syntax for Accord^], the new leaderless timestamp protocol. There was much
discussion about the right approach, which has now converged, defining the
syntax we will use for multi-key transactions and bringing CEP-15 ever closer.
+
+Also affecting CEP-15, *Avi Kivity* opened up
https://issues.apache.org/jira/browse/CASSANDRA-17762[a ticket^] about the
challenges of our eclectic usage of NULL strikes, while *Caleb Rackliffe*
continues to work on https://issues.apache.org/jira/browse/CASSANDRA-17719[CQL
support for multi-partition transactions^] where, Josh McKenzie has indicated,
the general sentiment is to go with “a SQL-congruent syntax."
+
+=== Discussed
+
+*Amit Pawar* started a thread that’s generated a discussion on the potential
benefits and shortcomings of
https://lists.apache.org/thread/5j8ljtpdw3g0gyrx6m31gh1gjdkztclg[a
multi-threaded flushing CommitLog^]. Benchmarking complex features like this
have proven difficult, and anyone with the knowledge of the subject is very
welcome to contribute.
+
+=== Discussed
+
+*Andrés de la Peña* has raised a question about inclusivity or exclusivity of
token ranges, and API consistency came up because
https://issues.apache.org/jira/browse/CASSANDRA-17575[CASSANDRA-17575^]. You
can follow and join in the discussion
https://lists.apache.org/thread/4tm626ffnqlvt4cbmopdfpd8w6fpqscd[here^].
+
+=== Discussed
+
+*Ekaterina Dimitrova* continues to raise and resolve many of the questions
about our properties, their units, and configuration parameters. This time the
https://lists.apache.org/thread/vgnjnkhbml7zocxpohth8x443rzgvbz5[issue^] was
the conversion of megabits and mebibytes producing double numbers, and how it
should be handled in JMX/nodetool when reporting it to the users.
+
+*Henrik Ingo* opened an email thread on the potential of developing a separate
Apache Cassandra’s ecosystem site or revamping the existing Ecosystem section
to potentially enable developers to maintain their own tool entries. You can
join the conversation and get involved in collaborating
https://lists.apache.org/thread/0839pvq8ob18782fpjy2coro17v7lyvg[here^].
+
+== User Space
+
+=== Spotify
+
+Speaking on the development of Backstage, the open platform for building
developer portals, and work on Backstage Kubernetes in 2021:
+
+[quote,'https://www.reddit.com/r/kubernetes/comments/lwb31v/were_the_engineers_rethinking_kubernetes_at/[Spotify^]']
+
+“Spotify is mostly on GCP so our developers use a mix of Google managed
storage products and self-managed ones. The managed storage solutions Spotify
developers use are Cloud Bigtable, Cloud Spanner, CloudSQL, and Cloud
Firestore. The unmanaged storage solutions Spotify devs start and operate
themselves on GCE include Apache Cassandra, PostgreSQL, Memcached, Elastic
Search, and Redis.”
