     <AssemblyVersion>0.20.0.0</AssemblyVersion>
-    <PackageReleaseNotes>Changes since v0.15.0:
-1: Add TransformGraphWithStringInputs.
-2: tf.trainer.load_graph, tf.trainer.freeze_graph
-3: Import Protobuf.Text
-4: Support YOLOv3 object detection
-5: Add implicitation for Operation to RefVariable</PackageReleaseNotes>
+    <PackageReleaseNotes>tf.net 0.20.x and above are based on tensorflow native 2.x.
+Eager Mode is added finally.
+It's not stable at this moment and missing many APIs, tf.net 0.15.x is more stable for production.
+Please be patient, we're working hard on missing functions, providing full tensorflow binding is our mission.</PackageReleaseNotes>

-### How to compile CSharp Native Interface
-
-
-git clone https://github.com/tensorflow/tensorflow
-
-`cd tensorflow/tensorflow`
-
-copy `csharp` folder to `tensorflow`, the csharp folder should be in the same parent directory with other language binding.
-
-`cd csharp`
-
-`bazel build //tensorflow/csharp:csni`
