TinyMCE 8.3.2

The TinyMCE 8.3.2 release includes an accompanying release of the Media Optimizer premium plugin.

Media Optimizer includes the following fix.

Uploading a video in TinyMCE 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 8.3.2, 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.

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 TinyMCE 8.3.2.
