 Change log file for Exim from version 4.21
 -------------------------------------------
@@ -199,6 +199,36 @@ PH/31 When doing a callout as part of verifying an address, Exim was not paying
 PH/32 Add the sender address, as F=<...>, to the log line when logging a
       timeout during the DATA phase of an incoming message.
 
+PH/33 Sieve envelope tests were broken for match types other than :is. I have
+      applied a patch sanctioned by the Sieve maintainer.
+
+PH/34 Change 4.50/80 broke Exim in that it could no longer handle cases where
+      the uid or gid is negative. A case of a negative gid caused this to be
+      noticed. The fix allows for either to be negative.
+
+PH/35 ACL_WHERE_MIME is now declared unconditionally, to avoid too much code
+      clutter, but the tables that are indexed by ACL_WHERE_xxx values had been
+      overlooked.
+
+PH/36 The change PH/12 above was broken. Fixed it.
+
+PH/37 Exim used to check for duplicate addresses in the middle of routing, on
+      the grounds that routing the same address twice would always produce the
+      same answer. This might have been true once, but it is certainly no
+      longer true now. Routing a child address may depend on the previous
+      routing that produced that child. Some complicated redirection strategies
+      went wrong when messages had multiple recipients, and made Exim's
+      behaviour dependent on the order in which the addresses were given.
+
+      I have moved the duplicate checking until after the routing is complete.
+      Exim scans the addresses that are assigned to local and remote
+      transports, and removes any duplicates. This means that more work will be
+      done, as duplicates will always all be routed, but duplicates are
+      presumably rare, so I don't expect this is of any significance.
+
+      For deliveries to pipes, files, and autoreplies, the duplicate checking
+      still happens during the routing process, since they are not going to be
+      routed further.
