+ 3. Transports now take a "max_parallel" option, to limit concurrency.
+
+ 4. Expansion operators ${ipv6norm:<string>} and ${ipv6denorm:<string>}.
+    The latter expands to a 8-element colon-sep set of hex digits including
+    leading zeroes. A trailing ipv4-style dotted-decimal set is converted
+    to hex.  Pure ipv4 addresses are converted to IPv4-mapped IPv6.
+    The former operator strips leading zeroes and collapses the longest
+    set of 0-groups to a double-colon.
+
+ 5. New "-bP config" support, to dump the effective configuration.
+
+ 6. New $dkim_key_length variable.
+
+ 7. New base64d and base64 expansion items (the existing str2b64 being a
+    synonym of the latter).  Add support in base64 for certificates.
+
+ 8. New main configuration option "bounce_return_linesize_limit" to
+    avoid oversize bodies in bounces. The dafault value matches RFC
+    limits.
