 ### 2.8.0 &mdash; 2021-06-12 <a id=“2.8.0”></a>
 
+### Update notice
+
+Due to a [breaking change in the Schema API](https://github.com/apache/pulsar/pull/10878), it may happen that some Pulsar Functions or Pulsar IO connectors fail to work, 
+throwing an `IncompatibleClassChangeError`.
+
+In this case, you need to rebuild your Function using Apache Pulsar 2.8.0 as a dependency and redeploy it.
+
+If you are running on Kubernetes, you can temporarily let the Functions Worker pod run with a previous version of Pulsar
+in order to not cause downtime.
+
+For more context about this issue, see [[Pulsar Functions and IO] Cannot upgrade Function built for Pulsar 2.7 to Pulsar 2.8](https://github.com/apache/pulsar/issues/11338).
