2D Path Package Deprecation The 2D Path package (com.unity.2d.path) will be deprecated from Unity 2022.1 onwards. The last supported version will be Unity 2021.2 (and therefore Unity 2021.3 LTS as well). What can you do? If you have been using the Path package to create splines, we strongly suggest you check out the Spline package that is currently in preview and give feedback to shape the package. This will help us consolidate our efforts in one place.
