+## Release Notes
+
+#### **Released**
+Apache #Cassandra 4.0-beta3, 3.11.9, 3.0.23, and 2.2.19 were released on
November 4 and are [in the
repositories](https://cassandra.apache.org/download/). Please pay attention to
release notes and let the community know if you encounter problems. Join the
Cassandra [mailing list](https://cassandra.apache.org/community/) to stay
updated.
+
+#### **Changed**
+Cassandra 4.0 is progressing toward GA. There are 1,390 total tickets and
remaining tickets represent 5.5% of total scope. Read the [full
summary](https://lists.apache.org/thread.html/r9c6cc19f67d3259e64abbe2b960b8914476d9bfa2463d57c6d5cc44b%40%3Cdev.cassandra.apache.org%3E)
shared to the dev mailing list and take a look at the [open
tickets](https://issues.apache.org/jira/secure/RapidBoard.jspa?rapidView=355&quickFilter=1661&quickFilter=1658)
that need reviewers.
+
+Cassandra 4.0 will be dropping support for older distributions of CentOS 5,
Debian 4, and Ubuntu 7.10. [Learn
more](https://lists.apache.org/thread.html/r513c507ef19a8524ad5389e548f3d5bbfeb9e7747f3ae4c57ec27329%40%3Cdev.cassandra.apache.org%3E).
+
+## Community Notes
+
+_Updates on Cassandra Enhancement Proposals (CEPs), how to contribute, and
other community activities._
+
+#### **Added**
+The community weighed options to address reads inconsistencies for Compact
Storage as noted in ticket
[CASSANDRA-16217](https://issues.apache.org/jira/browse/CASSANDRA-16217)
(committed). The conversation continues in ticket
[CASSANDRA-16226](https://issues.apache.org/jira/browse/CASSANDRA-16226) with
the aim of ensuring there are no huge performance regressions for common
queries when you upgrade from 2.x to 3.0 with Compact Storage tables or drop it
from a table on 3.0+.
+
+#### **Added**
+[CASSANDRA-16222](https://issues.apache.org/jira/browse/CASSANDRA-16222) is a
Spark library that can compact and read raw Cassandra SSTables into SparkSQL.
By reading the sstables directly from a snapshot directory, one can achieve
high performance with minimal impact to a production cluster. It was used to
successfully export a 32TB Cassandra table (46bn CQL rows) to HDFS in Parquet
format in around 70 minutes, a 20x improvement on previous solutions.
+
+#### **Changed**
+Great news for [CEP-2: Kubernetes
Operator](https://cwiki.apache.org/confluence/display/CASSANDRA/CEP-2+Kubernetes+Operator),
the community has agreed to [create a community-based
operator](https://lists.apache.org/thread.html/r9e1ff94d7b35cfc663bfa72d4ed3767e963e890f9e1199bfdb96bff0%40%3Cdev.cassandra.apache.org%3E)
by merging the cass-operator and CassKop. The work being done can be viewed on
GitHub [here](https://github.com/datastax/cass-operator).
+
+#### **Released**
+The Reaper community [announced
v2.1](https://thelastpickle.com/blog/2020/10/26/reaper-2_1-released-with-astra-support.html)
of its tool that schedules and orchestrates repairs of Apache Cassandra
clusters. Read the [docs](http://cassandra-reaper.io/docs/).
+
+#### **Released**
+Apache Cassandra 4.0-beta-1 was [released on
FreeBSD](https://lists.apache.org/thread.html/r040f39dcc038d607c0cc36731150ce8ecb67d7399304db97e7f8b38b%40%3Cuser.cassandra.apache.org%3E).

+#### **Netflix**
+“With these optimized Cassandra clusters in place, it now costs us 71% less to
operate clusters and we could store 35x more data than our previous
configuration.” - [Maulik
Pandey](https://netflixtechblog.com/building-netflixs-distributed-tracing-infrastructure-bb856c319304)
+
+#### **Yelp**
+“Cassandra is a distributed wide-column NoSQL datastore and is used at Yelp
for both primary and derived data. Yelp’s infrastructure for Cassandra has been
deployed on AWS EC2 and ASG (Autoscaling Group) for a while now. Each Cassandra
cluster in production spans multiple AWS regions.” - [Raghavendra D
Prabhu](https://engineeringblog.yelp.com/2020/11/orchestrating-cassandra-on-kubernetes-with-operators.html)
