CHANGELOG-v3.61.md

@@ -9,6 +9,8 @@
 * `ParticleEmitter.clearDeathZones` is a new method that will clear all previously created Death Zones from a Particle Emitter (thanks @rexrainbow)
 * `ParticleEmitter.clearEmitZones` is a new method that will clear all previously created Emission Zones from a Particle Emitter (thanks @rexrainbow)
 * The `GameObject.setTexture` method has 2 new optional parameters: `updateSize` and `updateOrigin`, which are both passed to the `setFrame` method and allows you to control if the size and origin of the Game Object should be updated when the texture is set (thanks @Trissolo)
+* Both the Animation Config and the Play Animation Config allow you to set a new boolean property `randomFrame`. This is `false` by default, but if set, it will pick a random frame from the animation when it _starts_ playback. This allows for much more variety in groups of sprites created at the same time, using the same animation. This is also reflected in the new `Animation.randomFrame` and `AnimationState.randomFrame` properties.
+* You can now use a `Phaser.Types.Animations.PlayAnimationConfig` object in the `anims` property of the `ParticleEmitter` configuration object. This gives you far more control over what happens to the animation when used by particles, including setting random start frames, repeat delays, yoyo, etc. Close #6478 (thanks @michalfialadev)
