Notice of the deprecation of the Text based "effect" components for Unity 2022 · Unity-UI-Extensions/com.unity.uiextensions · Discussion #428
Sadly, the two Text-based effects provided by the Unity UI Extensions project can no longer be supported in Unity 2022, as there is no corresponding support using TextMesh Pro features.
The controls affected are:
- BestFitOutline
- NicerOutline
TextMeshPro does provide some better outline features than the older Text versions, so these should fill your need should they still be needed.
