3New Features in Exim
4--------------------

6This file contains descriptions of new features that have been added to Exim,
7but have not yet made it into the main manual (which is most conveniently
8updated when there is a relatively large batch of changes). The doc/ChangeLog
9file contains a listing of all changes, including bug fixes.

11Version 4.62
12------------

141. The ${readsocket expansion item now supports Internet domain sockets as well
15 as Unix domain sockets. If the first argument begins "inet:", it must be of
16 the form "inet:host:port". The port is mandatory; it may be a number or the
17 name of a TCP port in /etc/services. The host may be a name, or it may be an
18 IP address. An ip address may optionally be enclosed in square brackets.
19 This is best for IPv6 addresses. For example:
20
21 ${readsocket{inet:[::1]:1234}{<request data>}...
22
23 Only a single host name may be given, but if looking it up yield more than
24 one IP address, they are each tried in turn until a connection is made. Once
25 a connection has been made, the behaviour is as for ${readsocket with a Unix
26 domain socket.

32The documentation is up-to-date for the 4.61 release. Major new features since
33the 4.60 release are:
34
35. An option called disable_ipv6, to disable the use of IPv6 completely.
36
37. An increase in the number of ACL variables to 20 of each type.
38
39. A change to use $auth1, $auth2, and $auth3 in authenticators instead of $1,
40 $2, $3, (though those are still set) because the numeric variables get used
41 for other things in complicated expansions.
42
843a41e8 43. The default for rfc1413_query_timeout has been changed from 30s to 5s.

46 resources used in pipe deliveries.
