+
+### Breaking Changes
+
+- The default value of `UIParticle.scale` has been changed from `10` to `1`.
+- `UIParticle` no longer inherits from `MaskableGraphic`.
+- If you are installing via git URL, add `?path=Packages/src`.
+   ```json
+   // v3/v4
+   "com.coffee.ui-particle": "https://github.com/mob-sakai/ParticleEffectForUGUI.git",
