+============================================================
+Breaking: #60135 - Recursive stdWrap is now only called once
+============================================================
+
+See :issue:`60135`
+
+Description
+===========
+
+If recursive stdWrap configuration was used, the stdWrap method was called twice, although the content
+was only rendered once. This performance overhead is now removed.
+
+
+Impact
+======
+
+If a recursive stdWrap configuration is used, which sets or acts on a global state like registers,
+the resulting rendering can now be different because the global state is now modified only once.
+
+
+Affected installations
+======================
+
+A TYPO3 instance is affected if there is TypoScript code like:
+
+::
+
+  page.1 = TEXT
+  page.1 {
+    value = Counter:
+    append = TEXT
+    append.data = register:Counter
+    stdWrap.append = LOAD_REGISTER
+    stdWrap.append {
+      Counter.cObject = TEXT
+      Counter.cObject.data = register:Counter
+      Counter.cObject.wrap = |+1
+      Counter.prioriCalc = 1
+    }
+  }
+
+..
+
+This now correctly outputs `Counter:1` instead of `Counter:2`
+
+Migration
+=========
+
+The usage of recursive stdWrap TypoScript configuration needs to be checked and probably adapted to fit the fixed behavior.
