+Exim version 4.61
+-----------------
+
+The default number of ACL variables of each type has been increased to 20, and
+it's possible to compile Exim with more. You can safely upgrade to this release
+if you already have messages on the queue with saved ACL variable values.
+However, if you downgrade from this release with messages on the queue, any
+saved ACL values they may have will be lost.
