+## [2.1.0]
 
 2.1.0 is a minor release of Helidon. It contains bug fixes and enhancements. Notable changes:
 
 - MicroProfile 3.3 support
 - New Helidon SE Fault Tolerance implementation. This also replaces Hystrix in the MicroProfile
   Fault Tolerance implementation.
+
+### Compatibility
+
+2.1.0 is API compatible with previous releases of 2.0. There are some minor
+behavioral changes:
+
 - Security: To remove accidental propagation of identity, all security providers that support outbound
   security were updated to only do outbound security when configured so. All of these providers
   now have an `outbound` configuration section that can define outbound targets. Documentation of
   providers was updated to match this new approach and is available in both MP and SE docs.
+- Custom jlink images produced by the helidon-mave-plugin now have a -jri suffix.
+  So the path to start your application looks something like:
+  target/helidon-quickstart-se-jri/bin/start
