foriero Hi, there are some incompatibilities with new Unity 20.17.1 Thank you, Marek. 15 Apr 2017 1:47 am Simple #if UNITY_5 || UNITY_2017_1_OR_NEWER solved all issues. Please can you update runtime repository? Thank you, Marek.
Pharan Thanks for reporting. We may just remove that since the latest unitypackage no longer supports Unity 4 and below. However, we typically don't accommodate larger breaking changes for beta versions of Unity since their APIs tend to be in flux.
