 - **Java11** (minimum) as Spark binaries are compiled with it.
 - **Spark `3.5.x` with Scala `2.13` and Hadoop `3.3`**
-    - Typically installed using [this binary](https://archive.apache.org/dist/spark/spark-3.5.3/spark-3.5.3-bin-hadoop3-scala2.13.tgz) on a single VM (no cluster necessary) where you want to run this job. This simple setup is recommended for most one-time migrations.

     - However we recommend using a Spark Cluster or a Spark Serverless platform like `Databricks` or `Google Dataproc` (that supports the above mentioned versions) for large (e.g. several terabytes) complex migrations OR when CDM is used as a long-term data-transfer utility and not a one-time job.
     
 Spark can be installed by running the following: -
 
 ```
-wget https://archive.apache.org/dist/spark/spark-3.5.3/spark-3.5.3-bin-hadoop3-scala2.13.tgz
-tar -xvzf spark-3.5.3-bin-hadoop3-scala2.13.tgz

 # Release Notes
 
+## [5.2.0] - 2025-xx-xx
+- Upgraded to use Spark `3.5.4`.
+- Cassandra Docker image tag is now set to `cassandra:5`.
+
 ## [5.1.4] - 2024-12-04
 - Bug fix: Any run started with a `previousRunId` that is not found in the `cdm_run_info` table (for whatever reason), will be executed as a fresh new run instead of doing nothing.
