+== Overview

+== Accompanying Premium plugin changes
+
+The following premium plugin updates were released alongside {productname} {release-version}.
+
+=== Media Optimizer
+
+The {productname} {release-version} release includes an accompanying release of the **Media Optimizer** premium plugin.
+
+**Media Optimizer** includes the following fix.
+
+=== Placeholder loading had two progress indicators
+// #TINY-13163
+
+Uploading a video in {productname} could display two progress indicators at the same time (a spinner and a progress bar), which unnecessarily cluttered the UI and made upload status harder to interpret. In {release-version}, the upload experience was updated to display only a single progress indicator: a progress bar when the upload duration can be estimated, or a spinner when the remaining time is unknown, resulting in a cleaner and clearer interface during video uploads.
+
+For information on the **Media Optimizer** plugin, see: xref:uploadcare.adoc[Media Optimizer].
+
+
+[[improvements]]
+== Improvements
+
+{productname} {release-version} also includes the following improvement:
+
+=== `uc-video` elements are not refreshed on undo/redo actions
+// #TINY-12884
+
+Previously, undo and redo operations rewrote the entire editor content, causing embedded `uc-video` elements to be rewritten and unintentionally refreshed, which disrupted playback and user experience. This behavior affected any content containing `uc-video`, as media elements were reloaded even when unrelated changes were undone or redone. The undo/redo mechanism has been updated to align with the existing iframe handling logic so that, when `uc-video` elements are present, only the modified portion of the content is refreshed rather than the full editor content. As a result, `uc-video` elements now remain stable and are no longer refreshed during undo or redo actions in {productname} {release-version}.
