# Changelog

> Latest updates and improvements to Bunny Optimizer

<Update label="2026-06-08" tags={["Improvement"]}>
  ## AVIF output area limit

  AVIF output is now limited to a maximum area of 4 megapixels. Larger images automatically fall back to another format (WebP, JPEG, or GIF) to keep latency low. A new `304` processing error code is returned when this limit is reached. [Learn more](/optimizer/dynamic-images/formats)
