+## [5.13.1] - 26/08/2022
+
+### Announcements
+
+In line with Unity's end of support of Unity 2019 LTS, we will no longer be actively supporting Unity 2019.
+
+We will also be deprecating some functionality and moving core utilities into a separate package.
+
+If you are using classes and methods that are marked as obsolete and will be moved to the new legacy package without a replacement, you may wish to use "#pragma warning disable 0618" at the start and "#pragma warning restore 0618" at the end of your method that makes use of it to suppress the warnings.
+
+If you have any concerns about this, please contact us on [Github Discussions](https://github.com/ultraleap/UnityPlugin/discussions)
+
+### Fixed
+- Tracking Binding is lost when reloading scenes on Android
+
+### Known issues 
+- Scenes containing the infrared viewer render incorrectly on Android build targets and in scriptable render pipelines such as URP and HDRP. 
+- Demo scenes do not start at the correct height for a seated user. The XR Plugin Management System adjusts the camera height. This means the user has to adjust components in the scene to the correct height - e.g. camera height. Currently our position is to support the legacy XR system height settings. 
+- Hands in Desktop scenes can appear far away from the camera 
+- Interactions callback scene allows blocks to be moved without doing a grasp pose. 
+- Capsule hands don't have a joint colour in HDRP 
+- Hand UI can become detached from hand when hand is removed from view
+- Multi-device (desktop) Scene camera position can become offset
+- FOV visualization does not display after changing render pipelines
