 Change log file for Exim from version 4.21
 -------------------------------------------
@@ -158,6 +158,54 @@ PH/22 As suggested by Dennis Davis, added a server_condition option to *all*
 PH/23 Testing for tls_required and lost_connection in a retry rule didn't work
       if any retry times were supplied.
 
+PH/24 Exim crashed if verify=helo was activated during an incoming -bs
+      connection, where there is no client IP address to check. In this
+      situation, the verify now always succeeds.
+
+PH/25 Applied John Jetmore's -Mset patch.
+
+PH/26 Added -bem to be like -Mset, but loading a message from a file.
+
+PH/27 In a string expansion for a processed (not raw) header when multiple
+      headers of the same name were present, leading whitespace was being
+      removed from all of them, but trailing whitespace was being removed only
+      from the last one. Now trailing whitespace is removed from each header
+      before concatenation. Completely empty headers in a concatenation (as
+      before) are ignored.
+
+PH/28 Fixed bug in backwards-compatibility feature of PH/09 (thanks to John
+      Jetmore). It would have mis-read ACL variables from pre-4.61 spool files.
+
+PH/29 After an address error (typically a 4xx response from a server), Exim
+      always tries the failing address if it appears in a new message, but
+      respects the retry time otherwise. This was implemented by checking for
+      being in a queue run, which isn't quite right. Now it checks the
+      "first_delivery" flag instead.
+
+PH/30 Exim was sometimes attempting to deliver messages that had suffered
+      address errors (4xx response to RCPT) over the same connection as other
+      messages routed to the same hosts. Such deliveries are always "forced",
+      so retry times are not inspected. This resulted in far too many retries
+      for the affected addresses. The effect occurred only when there were more
+      hosts than the hosts_max_try setting in the smtp transport when it had
+      the 4xx errors. Those hosts that it had tried were not added to the list
+      of hosts for which the message was waiting, so if all were tried, there
+      was no problem. Two fixes have been applied:
+
+      (i)  If there are any address or message errors in an SMTP delivery, none
+           of the hosts (tried or untried) are now added to the list of hosts
+           for which the message is waiting, so the message should not be a
+           candidate for sending over the same connection that was used for a
+           successful delivery of some other message. This seems entirely
+           reasonable: after all the message is NOT "waiting for some host".
+           This is so "obvious" that I'm not sure why it wasn't done
+           previously. Hope I haven't missed anything, but it can't do any
+           harm, as the worst effect is to miss an optimization.
+
+      (ii) If, despite (i), such a delivery is accidentally attempted, the
+           routing retry time is respected, so at least it doesn't keep
+           hammering the server.
+
