+The {productname} {release-version} release includes an accompanying release of the **TinyMCE AI** premium plugin.
+
+**TinyMCE AI** includes the following fix.
+
+==== Focus is no longer lost when deleting a context source using delete or backspace key.
+// #TINY-13949
+
+Previously, keyboard focus was lost when deleting a context source tag using the Delete or Backspace key in the TinyMCE AI sidebar chat view. After removing a context source, the focus disappeared entirely, making it difficult to continue keyboard navigation. This particularly affected accessibility and keyboard-only workflows.
+
+In {productname} {release-version}, focus management now tracks tag deletion events. When a context source tag is deleted, focus moves to either the previous context source tag or, when the first or only remaining tag is removed, back to the prompt input field. This ensures seamless keyboard navigation when managing context sources.
