What breaks

Amazon MSK supports a Kafka version until its end of support date. After that date:

A cluster still using the version is auto-upgraded to the recommended Kafka version.
The automatic upgrade can happen at any time after the end of support date.
No notification is sent before the upgrade.

For Kafka versions with a published end of support date, AWS states its intent to phase out support for newly created clusters. The page gives no date for this.

What to do

Upgrade the MSK cluster to the recommended Kafka version or a higher version before the end of support date. The recommended version is marked in Supported Apache Kafka versions.
Before upgrading, verify that the version of your client-side software supports the features in the new Kafka version. Server-side upgrades do not automatically update client applications.
Follow Upgrade the Apache Kafka version to upgrade with the console, the AWS CLI or the API. The CLI command aws kafka get-compatible-kafka-versions lists the versions the cluster can upgrade to.
Version downgrades are not supported.
See Best practices for version upgrades.
