+Subject: [PATCH] [CVE-2024-40896] Fix XXE protection in downstream code
+
+Some users set an entity's children manually in the getEntity SAX
+callback to restrict entity expansion. This stopped working after
+renaming the "checked" member of xmlEntity, making at least one
+downstream project and its dependants susceptible to XXE attacks.
+
+See #761.
