@@ -130,6 +130,7 @@ The following changes took place in the Pointer class:
 * Setting `padding` in a Text style configuration object would cause an error about calling split on undefined. Padding can now be applied both in the config and via `setPadding`.
 * `Tilemap.createBlankDynamicLayer` would fail if you provided a string for the tileset as the base tile width and height were incorrectly read from the tileset argument. Fix #4495 (thanks @jppresents)
 * `Tilemap.createDynamicLayer` would fail if you called it without setting the `x` and `y` arguments, even though they were flagged as being optional. Fix #4508 (thanks @jackfreak)
+* `RenderTexture.draw` didn't work if no `x` and `y` arguments were provided, even though they are optional, due to a problem with the way the frame cut values were added. The class has been refactored to prevent this, fixing issues like `RenderTexture.erase` not working with Groups. Fix #4528 (thanks @jbgomez21 @telinc1)
