+# .NET for Apache Spark 0.9 Release Notes
+
+### New Features and Improvements
+
+* Expose `DataStreamWriter.Foreach` API ([#387](https://github.com/dotnet/spark/pull/387))
+* Support UDF that returns `Row` object ([#376](https://github.com/dotnet/spark/pull/376), [#406](https://github.com/dotnet/spark/pull/406), [#411](https://github.com/dotnet/spark/pull/411))
+* Support for Bucketizer ([#378](https://github.com/dotnet/spark/pull/378))
+* Support `DateType` ([#420](https://github.com/dotnet/spark/pull/420))
+
+### Breaking Changes
+
+* The prior versions (<0.9) of `Microsoft.Spark.Worker` **are not compatible** with this release due to the internal changes related to UDFs.
+
+### Supported Spark Versions
+
+The following table outlines the supported Spark versions along with the microsoft-spark JAR to use with:
+
+<table>
+    <thead>
+        <tr>
+            <th>Spark Version</th>
+            <th>microsoft-spark JAR</th>
+        </tr>
+    </thead>
+    <tbody align="center">

+            <td>microsoft-spark-2.3.x-0.9.0.jar</td>
