+Exim version 4.94
+-----------------
+
+Some Transports now refuse to use tainted data in constructing their delivery
+location; this WILL BREAK configurations which are not updated accordingly.
+
+In particular: any Transport use of $local_user which has been relying upon
+check_local_user far away in the Router to make it safe, should be updated to
+replace $local_user with $local_part_verified.

 Exim version 4.93
