+**TinyMCE AI** includes the following fix.
+
+==== The Review sidebar no longer shows "No improvements found" after a review is applied
+// #TINY-14198
+
+Previously, hiding the Review sidebar and applying or skipping suggestions with the preview footer buttons did not reset the review state. Reopening the sidebar showed "No improvements found" instead of the available review options, requiring the editor to be reloaded. The review state now resets correctly, so the sidebar can be hidden and reopened to run new reviews.
