 * When taking a `snapshot` in WebGL it would often have an extra line of empty pixels at the top of the resulting image, due to a rounding error in the `WebGLSnapshot` function. Fix #4956 (thanks @gammafp @telinc1)
 * You can now draw a `Group` to a `RenderTexture`. Previously, it failed to pass the camera across, resulting in none of the Group children being drawn. Fix #5330 (thanks @somnolik)
 * `Particles.EmitterOp.setMethods` will now reset both `onEmit` and `onUpdate` to their default values. This allows you to reconfigure an emitter op with a new type of value and not have it stuck on the previous one. Fix #3663 (thanks @samme)
+* `Particles.EmitterOp` now cleanly separates between the different types of property configuration options. `start | end` will now ease between the two values, `min | max` will pick a random value between them and `random: []` will pick a random element. They no longer get mixed together. Fix #3608 (thanks @samme)
