+
+> This maintenance release replaces the 1.4.0 release.
+
+RDI’s mission is to help Redis customers sync Redis Enterprise with live data from their slow disk-based databases to:
+
+- Meet the required speed and scale of read queries and provide an excellent and predictable user experience.
+- Save resources and time when building pipelines and coding data transformations.
+- Reduce the total cost of ownership by saving money on expensive database read replicas.
+
+RDI keeps the Redis cache up to date with changes in the primary database, using a [_Change Data Capture (CDC)_](https://en.wikipedia.org/wiki/Change_data_capture) mechanism.
+It also lets you _transform_ the data from relational tables into convenient and fast data structures that match your app's requirements. You specify the transformations using a configuration system, so no coding is required.
+
+## Headlines
+
+-   Installation on [Kubernetes]({{< relref "/integrate/redis-data-integration/installation/install-k8s" >}}) using a [Helm chart](https://helm.sh/docs/). You can install on [OpenShift](https://docs.openshift.com/) or other flavours of K8s using Helm.
+
+- Improvements for installation on VMs:
+	- Installer checks if the OS firewall is enabled on Ubuntu and RHEL.
+	- Installer verifies DNS resolution from RDI components.
+	- Installer provides log lines from components that failed during RDI deployment if a problem occurs.
+	- Improved verification of RDI installation.
+	- Installer verifies if the RDI database is in use by another instance of RDI.
+	- Installer checks and warns if any [`iptables`](https://www.netfilter.org/projects/iptables/index.html) rules are set.
+	- Improved message when RDI tries to connect to its Redis database with invalid TLS keys.
+
+## Issues fixed
+
+- **RDSC-2806**: Remove incorrectly created deployment.
+- **RDSC-2792**: Disable `kubectl run` checks.
+- **RDSC-2782**: Fix `coredns` issue.
+
+## Limitations
+
+RDI can write data to a Redis Active-Active database. However, it doesn't support writing data to two or more Active-Active replicas. Writing data from RDI to several Active-Active replicas could easily harm data integrity as RDI is not synchronous with the source database commits.
