Cassandra is moving to a monthly release process called Tick-Tock. Even-numbered releases (e.g. 3.2) contain new features; odd-numbered releases (e.g. 3.3) contain bug fixes only. If a critical bug is found, a patch will be released against the most recent bug fix release. Read more about tick-tock here.

The Apache Cassandra project also provide official Debian™ packages (which are not a product of Debian™). To use those packages, you can use:
deb http://www.apache.org/dist/cassandra/debian <release series> main deb-src http://www.apache.org/dist/cassandra/debian <release series> main

If after running apt-get update, you see an error message like:
GPG error: http://www.apache.org unstable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 0353B12C
you will need to add the public key of the current Cassandra “release manager”, here
0353B12C. You can do that with:
gpg --keyserver pgp.mit.edu --recv-keys <public key> gpg --export --armor <public key> | sudo apt-key add -
<public key> is the key to add (
0353B12C in the example above). The list of Apache contributors public keys is
available at https://www.apache.org/dist/cassandra/KEYS.
Once set up, installing is done as usual with:
sudo apt-get update sudo apt-get install cassandra
