+
+## What's new in Klaw 2.9.0
+
+### Redesigned screens with React UI
+
+In this release, we have redesigned the user interface using React to enhance the user experience and provide a more intuitive design.
+
+Key updates in the new React UI include:
+
+- Support for Json Schemas
+
+To turn off the preview for the new Klaw user interface, open the
+`application.properties` file on the Klaw **core** module, and set the
+value of the following property to `false` (Effective from version 2.4.0, it
+is true by default):
+
+```properties
+    #Enable new Klaw user interface
+    klaw.coral.enabled=false
+```
+
+:::note
+We are taking an incremental, feedback-driven approach in rolling out
+the new Klaw interfaces. By providing the feature flag to preview the user
+interfaces, we would like you to share your valuable
+[feedback](https://github.com/aiven/klaw/issues/new?assignees=&labels=&template=03_feature.md).
+:::
+
+### JSON schema support in Coral and Angular
+
+Klaw now supports provisioning JSON schemas through both the Angular and React UI. Previously, only Schemes of type Avro were supported.
+
+### Beta release of ACL claim feature
+
+We are excited to announce that the beta version of Claim ACL/Subscription feature has been released. However, some limitations will be addressed in the upcoming releases. For more information about these limitations, see ACL Claim.
+
+### Improvements
+
+- Admin guards on all APIs for roles for enhanced security and enhanced user feedback
+- Delete service users when ACLs are deleted
+- Declined user requests can be reused
+
+### Bug fixes
+
+- Allowed creating new users with an email address as a username
+- Fixed the default schema version on promote to be an informational message in angular UI
+- Fixed unused scripts and unsafe links
+- Fixed `target=blank` vulnerability
+
+### Database upgrade
+
+This release adds a new primary key to the `kwregisterusers` table, allowing previously denied usernames to be reused in future requests.
+

+# Claim a subscription
+
+To claim an existing subscription in Klaw from another team.
+
+:::note
+This feature is in beta as of Klaw release 2.9.0, with improvements planned for upcoming releases. Currently, it is available only through the older Angular user interface.
+:::
+
+## About claim subscription
+
+Subscription claims can currently only be initiated through the Angular (old) UI. However, transfer approval is possible through any user interface (old and new).
+
+Klaw has introduced a new workflow requiring approval from multiple parties:
+
+1. **Topic owner approval (data owner)**: The topic (data) owner, as the data owner, must approve the request first.
+2. **Existing owner approval (subscription transfer)**: The current subscription owner must approve the transfer to the new team.
+
+The **Service User** associated with the subscription won't be transferred until **all** subscriptions owned by the original team for that user are transferred to the new team.
+
+:::note
+While the UI might not explicitly state it, the topic owner's approval is always required first. We're actively working on improving the UI clarity in future updates.
+:::
+
+## Create a claim subscription request
+
+Once a subscription is created in an environment, another team can claim the subscription associated with a topic.
+
+1. In Klaw, click **Topics** on the navigation bar.
+2. Select the Apache Kafka® topic that has the subscription you want to claim.
+3. Click **Claim** from the subscriptions table on the topic overview.
+
+   :::note
+   Any team other than the current subscription owner can initiate this claim. The process requires two approvals: one from the topic owner for allowing another team access to their data and another from the current subscription holder.
+   :::
+
+4. Confirm that you want to claim the subscription.
+5. This action creates a subscription claim request.
+
+## Limitations
+
+The current implementation of the subscription claim process has the following limitations:
+
+- **Service user selection visibility**: The interface does not provide immediate confirmation of the selected service user when claiming a subscription. The selection details and the approval workflow become visible after submitting the claim and are available on the **My Teams Requests** page, indicating the necessary approvals.
+- **IP-based subscription support**:Claims for IP-based subscriptions are not yet supported. It is advisable to avoid using this feature for IP-based subscriptions until Klaw version 2.10.0 provides the necessary support.
