+Exim version 4.62
+-----------------
+
+TF/01 Fix the add_header change below (4.61 PH/55) which had a bug that (amongst
+      other effects) broke the use of negated acl sub-conditions.
+
+PH/01 ${readsocket now supports Internet domain sockets (modified John Jetmore
+      patch).
+
+PH/02 When tcp-wrappers is called from Exim, it returns only "deny" or "allow".
+      "Deny" causes Exim to reject the incoming connection with a 554 error.
+      Unfortunately, if there is a major crisis, such as a disk failure,
+      tcp-wrappers gives "deny", whereas what one would like would be some
+      kind of temporary error. A kludge has been added to help with this.
+      Before calling hosts_ctl(), errno is set zero. If the result is "deny", a
+      554 error is used if errno is still zero or contains ENOENT (which occurs
+      if either of the /etc/hosts.{allow,deny} files is missing). Otherwise, a
+      451 error is used.

+PH/63 Changed the macro HAVE_LOGIN_CAP (see PH/41 for this release above) to
+      HAVE_SETCLASSRESOURCES because there are different APIs in use that all
+      use login_cap.h, so on its own it isn't the distinguishing feature. The
+      new name refers directly to the setclassresources() function.
+
+PH/65 Added configuration files for NetBSD3.
+
+PH/66 Updated OS/Makefile-HP-UX for gcc 4.1.0 with HP-UX 11.
+
+PH/67 Fixed minor infelicity in the sorting of addresses to ensure that IPv6
+      is preferred over IPv4.
+
+PH/68 The bounce_return_message and bounce_return_body options were not being
+      honoured for bounces generated during the reception of non-SMTP messages.
+      In particular, this applied to messages rejected by the ACL. This bug has
+      been fixed. However, if bounce_return_message is true and bounce_return_
+      body is false, the headers that are returned for a non-SMTP message
+      include only those that have been read before the error was detected.
+      (In the case of an ACL rejection, they have all been read.)
+
+PH/69 The HTML version of the specification is now built in a directory called
+      spec_html instead of spec.html, because the latter looks like a path with
+      a MIME-type, and this confuses some software.
+
+PH/70 Catch two compiler warnings in sieve.c.
+
+PH/71 Fixed an obscure and subtle bug (thanks Alexander & Matthias). The
+      function verify_get_ident() calls ip_connect() to connect a socket, but
+      if the "connect()" function timed out, ip_connect() used to close the
+      socket. However, verify_get_ident() also closes the socket later, and in
+      between Exim writes to the log, which may get opened at this point. When
+      the socket was closed in ip_connect(), the log could get the same file
+      descriptor number as the socket. This naturally causes chaos. The fix is
+      not to close the socket in ip_connect(); the socket should be closed by
+      the function that creates it. There was only one place in the code where
+      this was missing, in the iplookup router, which I don't think anybody now
+      uses, but I've fixed it anyway.
+
+PH/72 Make dns_again_means_nonexist apply to lookups using gethostbyname() as
+      well as to direct DNS lookups. Otherwise the handling of names in host
+      lists is inconsistent and therefore confusing.
