+
+**Image Optimizer** includes the following fixes.
+
+==== Images with existing `srcset` were not handled correctly.
+
+An issue was identified where images with an existing `srcset` attribute containing an Uploadcare URL were being processed incorrectly.
+
+The problem occurred when attempting to update an `srcset` attribute that did not contain an Uploadcare URL. In such cases, no changes were applied, resulting in the image failing to update if the existing `srcset` had a different structure.
+
+{productname} {release-version} resolves this issue by exclusively targeting `srcset` attributes with Uploadcare URLs. This ensures that all relevant images are updated correctly, with the `srcset` being regenerated from scratch to incorporate any modifications made.
