+========================================================
+Deprecation: #85086 - GeneralUtility::arrayToLogString()
+========================================================
+
+See :issue:`85086`
+
+Description
+===========
+
+The method :php:`GeneralUtility::arrayToLogString()`, responsible for formatting an array to a string
+ready for logging or output, has been marked as deprecated.
+
+
+Impact
+======
+
+Calling the method directly will trigger a deprecation warning.
+
+
+Affected Installations
+======================
+
+Any TYPO3 installation with third-party extensions using this method.
+
+
+Migration
+=========
+
+For logging purposes, switch to PSR-3 compatible logging where a log-writer is taking care of outputting / storing
+this information properly.
+
+For other purposes, like CLI-command output, it is recommended to implement this functionality directly in the
+corresponding CLI command.
