-PH/01. The format in which GnuTLS parameters are written to the gnutls-param
-       file in the spool directory has been changed. This change has been made
-       to alleviate problems that some people had with the generation of the
-       parameters by Exim when /dev/random was exhausted. In this situation,
-       Exim would hang until /dev/random acquired some more entropy.
+PH/01 There is a new global option called disable_ipv6, which does exactly what
+      its name implies. If set true, even if the Exim binary has IPv6 support,
+      no IPv6 activities take place. AAAA records are never looked up for host
+      names given in manual routing data or elsewhere. AAAA records that are
+      received from the DNS as additional data for MX records are ignored. Any
+      IPv6 addresses that are listed in local_interfaces, manualroute route
+      data, etc. are also ignored. If IP literals are enabled, the ipliteral
+      router declines to handle IPv6 literal addresses.
+
+PH/02 There are now 20 of each type of ACL variable by default (instead of 10).
+      It is also possible to change the numbers by setting ACL_CVARS and/or
+      ACL_MVARS in Local/Makefile. Backward compatibility is maintained if you
+      upgrade to this release with existing messages containing ACL variable
+      settings on the queue. However, going in the other direction
+      (downgrading) will not be compatible; the values of ACL variables will be
+      lost.
+
+PH/03 If quota_warn_message contains a From: header, Exim now refrains from
+      adding the default one. Similarly, if it contains a Reply-To: header, the
+      errors_reply_to option, if set, is not used.
+
+PH/04 The variables $auth1, $auth2, $auth3 are now available in authenticators,
+      containing the same values as $1, $2, $3. The new variables are provided
+      because the numerical variables can be reset during string expansions
+      (for example, during a "match" operation) and so may lose the
+      authentication data. The preferred variables are now the new ones, with
+      the use of the numerical ones being deprecated, though the support will
+      not be removed, at least, not for a long time.

 
 

-       The new code exports and imports the DH and RSA parameters in PEM
-       format. This means that the parameters can be generated externally using
-       the certtool command that is part of GnuTLS.
+PH/05 The "control=freeze" ACL modifier can now be followed by /no_tell. If
+      the global option freeze_tell is set, it is ignored for the current
+      message (that is, nobody is told about the freezing), provided all the
+      "control=freeze" modifiers that are obeyed in the current message have
+      the /no_tell option.

 
 

-       To replace the parameters with new ones, instead of deleting the file
-       and letting Exim re-create it, you can generate new parameters using
-       certtool and, when this has been done, replace Exim's cache file by
-       renaming. The relevant commands are something like this:
+PH/06 In both GnuTLS and OpenSSL, an expansion of tls_privatekey that results
+      in an empty string is now treated as unset.

 
 

-         # rm -f new.params
-         # touch new.params
-         # chown exim:exim new.params
-         # chmod 0400 new.params
-         # certtool --generate-privkey --bits 512 >new.params
-         # echo "" >>new.params
-         # certtool --generate-dh-params --bits 1024 >> new.params
-         # mv new.params params
+PH/07 There is a new log selector called sender_verify_fail, which is set by
+      default. If it is unset, the separate log line that gives details of a
+      sender verification failure is not written. Log lines for the rejection
+      of SMTP commands (e.g. RCPT) contain just "sender verify failed", so some
+      detail is lost.

 
 

-       If Exim never has to generate the parameters itself, the possibility of
-       stalling is removed.
+PH/08 The default for dns_check_names_pattern now allows slashes within names,
+      as there are now some PTR records that contain slashes. This check is
+      only to protect against broken name servers that fall over on strange
+      characters, so the fact that it applies to all lookups doesn't matter.
