+
+We're excited to announce the release of [Kroxylicious 0.20.0](https://github.com/kroxylicious/kroxylicious/releases/tag/v0.20.0)! There's been a lot of action, check out the full [Changelog](https://github.com/kroxylicious/kroxylicious/blob/main/CHANGELOG.md#0200) for everything including deprecations, changes, and removals.
+
+Here are the highlights:
+
+### Connection Expiration Filter
+
+Thanks to the work of [May-Abo](https://github.com/May-Abo), a new filter joins the family! The Connection Expiration filter closes client connections after a configurable maximum age. This is perfect for dynamic environments like Kubernetes where you want to rebalance connections across proxy instances as pods scale up or down.
+
+### Entity Isolation Filter
+
+Multi-tenancy gets even better with the Entity Isolation filter. Initially supporting `groupId` and `transactionalId` entity types, this filter helps you enforce isolation boundaries between tenants sharing a cluster.
+
+### Record Validation Filter - Apicurio v3 Upgrade
+
+- Record validation just got a major upgrade with Apicurio v3. The default schema identification has changed from `globalId` to `contentId` for better interoperability with Confluent-based Kafka clients. To support migrations, you can still use the old behavior by setting `wireFormatVersion` to `V2`, though this mode is deprecated and will be removed in a future release.
+- The schema validation filter can now connect to a schema registry protected by internally signed TLS certificates. One less obstacle for air-gapped or enterprise environments.
+
+### Kubernetes Operator Enhancements
+
+Two improvements for Kubernetes users:
+- **OpenShift Route Support**: Enable external access to Virtual Clusters via OpenShift Routes using `KafkaProxyIngress.spec.openShiftRoute`. Off-cluster client access is now a breeze on OpenShift.
+- **Server-Side Apply**: The operator now uses Server-Side Apply for all dependent resources. Existing deployments are unaffected, and externally-applied patches (like annotations from observability tooling) will now survive operator reconciles.
+
+### Javadocs on the Website
+
+Public API Javadocs are now published alongside version-specific documentation on [kroxylicious.io](https://kroxylicious.io/documentation/0.20.0/javadoc/index.html), making it easier to explore our APIs without leaving your browser.
+
+### Configuration Improvements
+
+- **Configurable Netty shutdown**: New `shutdownQuietPeriod` and `shutdownTimeout` fields give you fine-grained control over Netty shutdown behavior with Go-style durations.
+- **Duration serialization**: Filter Config classes can now use `Duration` types that automatically serialize to/from Go-style strings (e.g., "1h") without any annotations.
+
+### Artefacts
+
+Binary distributions and container images are available on the [download](https://kroxylicious.io/download/0.20.0/) page.
+
+### Feedback
+
+We'd love to hear from you! Whether you're kicking the tyres, running Kroxylicious in production, or just find the project interesting — drop by and say hello.
+You can reach us through [Slack](https://kroxylicious.slack.com), [GitHub](https://github.com/kroxylicious/kroxylicious/issues) or even [bsky](https://bsky.app/profile/kroxylicious.io)), or tell us in person on one of our upcoming [community calls]({% link join-us/community-call/index.md %}).
