+Exim version 4.68
+-----------------
+
+PH/01 Another patch from the Sieve maintainer.
+
+PH/02 When an IPv6 address is converted to a string for single-key lookup
+      in an address list (e.g. for an item such as "net24-dbm;/net/works"),
+      dots are used instead of colons so that keys in lsearch files need not
+      contain colons. This was done some time before quoting was made available
+      in lsearch files. However, iplsearch files do require colons in IPv6 keys
+      (notated using the quote facility) so as to distinguish them from IPv4
+      keys. This meant that lookups for IP addresses in host lists did not work
+      for iplsearch lookups.
+
+      This has been fixed by arranging for IPv6 addresses to be expressed with
+      colons if the lookup type is iplsearch. This is not incompatible, because
+      previously such lookups could never work.
+
+      The situation is now rather anomolous, since one *can* have colons in
+      ordinary lsearch keys. However, making the change in all cases is
+      incompatible and would probably break a number of configurations.
+
+TK/01 Change PRVS address formatting scheme to reflect latests BATV draft
+      version.
+
+MH/01 The "spam" ACL condition code contained a sscanf() call with a %s
+      conversion specification without a maximum field width, thereby enabling
+      a rogue spamd server to cause a buffer overflow. While nobody in their
+      right mind would setup Exim to query an untrusted spamd server, an
+      attacker that gains access to a server running spamd could potentially
+      exploit this vulnerability to run arbitrary code as the Exim user.
+
+TK/02 Bugzilla 502: Apply patch to make the SPF-Received: header use
+      $primary_hostname instead of what libspf2 thinks the hosts name is.
+
+MH/02 The dsearch lookup now uses lstat(2) instead of stat(2) to look for
+      a directory entry by the name of the lookup key. Previously, if a
+      symlink pointed to a non-existing file or a file in a directory that
+      Exim lacked permissions to read, a lookup for a key matching that
+      symlink would fail. Now it is enough that a matching directory entry
+      exists, symlink or not. (Bugzilla 503.)

+      picked up by some special patterns. I have improved the selection

+PH/39 In a list of hosts for manualroute, if one item (either because of multi-
+      homing or because of multiple MX records with /mx) generated more than
+      one IP address, and the following item turned out to be the local host,
+      all the secondary addresses of the first item were incorrectly removed
+      from the list, along with the local host and any following hosts (which
+      is what is supposed to happen).
+
+PH/40 When Exim receives a message, it writes the login name, uid, and gid of
+      whoever called Exim into the -H file. In the case of the daemon it was
+      behaving confusingly. When first started, it used values for whoever
+      started the daemon, but after a SIGHUP it used the Exim user (because it
+      calls itself on a restart). I have changed the code so that it now always
+      uses the Exim user.
+
+PH/41 (Following a suggestion from Tony Finch) If all the RCPT commands in a
+      message are rejected with the same error (e.g. no authentication or bad
+      sender address), and a DATA command is nevertheless sent (as can happen
+      with PIPELINING or a stupid MUA), the error message that was given to the
+      RCPT commands is included in the rejection of the DATA command. This is
+      intended to be helpful for MUAs that show only the final error to their
+      users.
+
+PH/42 Another patch from the Sieve maintainer.
+
+SC/02 Eximstats - Differentiate between permanent and temporary rejects.
+      Eximstats - Fixed some broken HTML links and added missing column headers
+                  (Jez Hancock).
+      Eximstats - Fixed Grand Total Summary Domains, Edomains, and Email
+                  columns for Rejects, Temp Rejects, Ham, and Spam rows.
+
+SC/03 Eximstats - V1.58 Fix to get <> and blackhole to show in edomain tables.
+
+PH/43 Yet another patch from the Sieve maintainer.
+
+PH/44 I found a way to check for a TCP/IP connection going away before sending
+      the response to the final '.' that terminates a message, but only in the
+      case where the client has not sent further data following the '.'
+      (unfortunately, this is allowed). However, in many cases there won't be
+      any further data because there won't be any more messages to send. A call
+      to select() can be used: if it shows that the input is "ready", there is
+      either input waiting, or the socket has been closed. An attempt to read
+      the next input character can distinguish the two cases. Previously, Exim
+      would have sent an OK response which the client would never have see.
+      This could lead to message repetition. This fix should cure that, at
+      least in a lot of common cases.
+
+PH/45 Do not advertise STARTTLS in response to HELP unless it would be
+      advertised in response to EHLO.
