+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.
+
+PH/38 Installed a patch from Ian Freislich, with the agreement of Tom Kistner.
+      It corrects a timeout issue with spamd. This is Ian's comment: "The
+      background is that sometimes spamd either never reads data from a
+      connection it has accepted, or it never writes response data. The exiscan
+      spam.[ch] uses a 3600 second timeout on spamd socket reads, further, it
+      blindly assumes that writes won't block so it may never time out."
+
+PH/39 Allow G after quota size as well as K and M.
+
+PH/40 The value set for $authenticated_id in an authenticator may not contain
+      binary zeroes or newlines because the value is written to log lines and
+      to spool files. There was no check on this. Now the value is run through
+      the string_printing() function so that such characters are converted to
+      printable escape sequences.
