+##### Note on backward compatibility
+The [backward incompatible](http://ydk.cisco.com/py/docs/backward_compatibility.html) changes introduced with `0.6.0` python release include:
+ * **Installation:** When installing `YDK-Py`, there is a new system requirement which needs to be installed. This is the `libydk` library, which is available on the DevHub website for various OS platforms. Please refer to the [system requirements](https://github.com/CiscoDevNet/ydk-py/blob/master/README.rst#system-requirements) for details.
+* **Windows support:** From release ``0.6.0`` onwards, YDK is no longer supported on the Windows platform. We plan to add back support for this platform in the future.
+* **API changes:** Please refer to the [developer guide](http://ydk.cisco.com/py/docs/developer_guide.html) and [API guide](http://ydk.cisco.com/py/docs/api_guide.html) for details about APIs and how to use them.
+   * `NetconfServiceProvider` no longer has the `close()` method. There is no need to explicitly close the provider as it will be automatically cleaned up when the object goes out of scope.
+   * `YFilter` has replaced the functionality of the `READ` and `DELETE` objects
+   * When using logging, the suggested level for users of YDK is `INFO` as `DEBUG` provides highly detailed logging suitable for developers working on YDK
+   * The type names of `enumerations` and `identities` no longer have `Enum` or `Identity` in their names. For example, the  identity `InterfaceTypeIdentity` in `ydk.models.ietf.ietf_interfaces` is now renamed to just `InterfaceType`
+
 
 #### C++
  * Renamed some of the methods in path API to be verbs like `DataNode::get_schema()` instead of nouns like `DataNode::schema()` ([#498](https://github.com/CiscoDevNet/ydk-gen/pull/498))
