New Features in Exim
--------------------
Version 4.61
------------
-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.
-
-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.
-
-PH/06 In both GnuTLS and OpenSSL, an expansion of tls_privatekey that results
- in an empty string is now treated as unset.
-
-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.
-
-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.
-
-PH/09 The default for rfc4131_query_timeout has been changed from 30s to 5s.
+The documentation is up-to-date for the 4.61 release. Major new features since
+the 4.60 release are:
+. An option called disable_ipv6, to disable the use of IPv6 completely.
+
+. An increase in the number of ACL variables to 20 of each type.
+
+. A change to use $auth1, $auth2, and $auth3 in authenticators instead of $1,
+ $2, $3, (though those are still set) because the numeric variables get used
+ for other things in complicated expansions.
+
+. The default for rfc4131_query_timeout has been changed from 30s to 5s.
+
+. It is possible to use setclassresources() on some BSD OS to control the
+ resources used in pipe deliveries.
+
+. A new ACL modifier called add_header, which can be used with any verb.
+
+. More errors are detectable in retry rules.
+
+There are a number of other additions too.
