 **TinyMCE AI** includes the following fixes, improvements and additions.
 
+==== It was possible to submit white space only titles when renaming a conversation
+// #TINY-14251
+
+Previously, in the TinyMCE AI Chat History panel, renaming a conversation and clearing the title field would correctly disable the Save button. However, pressing Enter while the input was empty or contained only whitespace bypassed the disabled button and submitted the empty title. This resulted in conversations being saved with blank names, making them difficult to identify in the history.
+
+In {productname} {release-version}, the save handler now validates the title value directly, applying the same check used to disable the Save button. Pressing Enter with an empty or whitespace-only title no longer submits the rename, ensuring all conversations retain a meaningful title in the Chat History.
