+==========================================================
+Deprecation: #80440 - EXT:lowlevel ArrayBrowser->wrapValue
+==========================================================
+
+See :issue:`80440`
+
+Description
+===========
+
+The method ``ArrayBrowser->wrapValue`` in EXT:lowlevel has been marked as deprecated, since the sole
+logic was to wrap the incoming string into htmlspecialchars().
+
+
+Impact
+======
+
+Calling the method will trigger a deprecation warning.
+
+
+Affected Installations
+======================
+
+Any TYPO3 installation using the EXT:lowlevel ArrayBrowser class in a custom extension.
+
+
+Migration
+=========
+
+Remove the call to the method and directly use ``htmlspecialchars()`` instead.
