+
+The Kroxylicious project is very pleased to announce the release of [Kroxylicious 0.11.0](https://github.com/kroxylicious/kroxylicious/releases/tag/v0.11.0). See the [Changelog](https://github.com/kroxylicious/kroxylicious/blob/main/CHANGELOG.md#0110) for a list of changes and summary of Deprecations, Changes and Removals.
+
+### Revamped configuration file format
+
+The main change in this release is a revamped configuration file format.  We hope this change means that Kroxylicious is more intuitive to configure.  The changes are fully described in the [changelog](https://github.com/kroxylicious/kroxylicious/blob/main/CHANGELOG.md#0110) but
+to help you quickly update your configuration, compare the [new](https://raw.githubusercontent.com/kroxylicious/kroxylicious/refs/tags/v0.11.0/kroxylicious-app/example-proxy-config.yaml) and [old](https://raw.githubusercontent.com/kroxylicious/kroxylicious/refs/tags/v0.10.0/kroxylicious-app/example-proxy-config.yaml) configurations.
+
+Backward compatibility has been maintained with the old format, so your old configuration will keep working for the next few releases. You'll see deprecation warnings in the logs during startup. 
+
+### New policy to control record encryption's behaviour when a KEK doesn't resolve
+
+We've added a new feature that lets you define Record Encryption's behaviour when it cannot resolve a key encryption key (KEK) for a topic. You can now choose to have the Record Encrypton filter reject the producer batch so that the application will see errors,
+rather than letting the records through unencrypted.  The default behaviour is unchanged.
+
+### Feedback
+
+Please let us know, through [Slack](https://kroxylicious.slack.com), [GitHub](https://github.com/kroxylicious/kroxylicious/issues) or even [bsky](https://bsky.app/profile/kroxylicious.io)), if you find the project interesting or helpful and especially if you have deployed it in production.
