 | 14 | +> This maintenance release replaces the 1.4.0 release.  | 
 | 15 | +
  | 
 | 16 | +RDI’s mission is to help Redis customers sync Redis Enterprise with live data from their slow disk-based databases to:  | 
 | 17 | + | 
 | 18 | +- Meet the required speed and scale of read queries and provide an excellent and predictable user experience.  | 
 | 19 | +- Save resources and time when building pipelines and coding data transformations.  | 
 | 20 | +- Reduce the total cost of ownership by saving money on expensive database read replicas.  | 
 | 21 | + | 
 | 22 | +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.  | 
 | 23 | +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.  | 
 | 24 | + | 
 | 25 | +## Headlines  | 
 | 26 | + | 
 | 27 | +-   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.  | 
 | 28 | + | 
 | 29 | +- Improvements for installation on VMs:  | 
 | 30 | +	- Installer checks if the OS firewall is enabled on Ubuntu and RHEL.  | 
 | 31 | +	- Installer verifies DNS resolution from RDI components.  | 
 | 32 | +	- Installer provides log lines from components that failed during RDI deployment if a problem occurs.  | 
 | 33 | +	- Improved verification of RDI installation.  | 
 | 34 | +	- Installer verifies if the RDI database is in use by another instance of RDI.  | 
 | 35 | +	- Installer checks and warns if any [`iptables`](https://www.netfilter.org/projects/iptables/index.html) rules are set.  | 
 | 36 | +	- Improved message when RDI tries to connect to its Redis database with invalid TLS keys.  | 
 | 37 | + | 
 | 38 | +## Issues fixed  | 
 | 39 | + | 
 | 40 | +- **RDSC-2806**: Remove incorrectly created deployment.  | 
 | 41 | +- **RDSC-2792**: Disable `kubectl run` checks.  | 
 | 42 | +- **RDSC-2782**: Fix `coredns` issue.  | 
 | 43 | + | 
 | 44 | +## Limitations  | 
 | 45 | + | 
 | 46 | +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.  |
