CHANGELOG.md

@@ -132,6 +132,7 @@ If you used any of them in your code, please update to the new function names be
 * `BitmapText.dropShadowAlpha` is a new property that sets the alpha of the Bitmap Text drop shadow.
 * `BatchChar` is a new internal private function for batching a single character of a Bitmap Text to the pipeline.
 * If you give an invalid Bitmap Font key, the Bitmap Text object will now issue a `console.warn`.
+* Setting the `color` value in the `DynamicBitmapText.setDisplayCallback` would inverse the red and blue channels if the color was not properly encoded for WebGL. It is now encoded automatically, meaning you can pass normal hex values as the colors in the display callback. Fix #5225 (thanks @teebarjunk)
