+Version 4.83
+------------
+
+ 1. If built with the EXPERIMENTAL_PROXY feature enabled, Exim can be
+ configured to expect an initial header from a proxy that will make the
+ actual external source IP:host be used in exim instead of the IP of the
+ proxy that is connecting to it.
+
+
Version 4.82
------------
8. New expansion operators ${listnamed:name} to get the content of a named list
and ${listcount:string} to count the items in a list.
- 9. New global option "gnutls_enable_pkcs11", defaults false. The GnuTLS
+ 9. New global option "gnutls_allow_auto_pkcs11", defaults false. The GnuTLS
rewrite in 4.80 combines with GnuTLS 2.12.0 or later, to autoload PKCS11
modules. For some situations this is desirable, but we expect admin in
those situations to know they want the feature. More commonly, it means
through, thus breakage. So we explicitly inhibit the PKCS11 initialisation
unless this new option is set.
+ Some older OS's with earlier versions of GnuTLS might not have pkcs11 ability,
+ so have also added a build option which can be used to build Exim with GnuTLS
+ but without trying to use any kind of PKCS11 support. Uncomment this in the
+ Local/Makefile:
+
+ AVOID_GNUTLS_PKCS11=yes
+
10. The "acl = name" condition on an ACL now supports optional arguments.
New expansion item "${acl {name}{arg}...}" and expansion condition
"acl {{name}{arg}...}" are added. In all cases up to nine arguments
20. Callout connections can now AUTH; the same controls as normal delivery
connections apply.
+21. Support for DMARC, using opendmarc libs, can be enabled. It adds new
+ options: dmarc_forensic_sender, dmarc_history_file, and dmarc_tld_file.
+ It adds new expansion variables $dmarc_ar_header, $dmarc_status,
+ $dmarc_status_text, and $dmarc_used_domain. It adds a new acl modifier
+ dmarc_status. It adds new control flags dmarc_disable_verify and
+ dmarc_enable_forensic.
+
+22. Add expansion variable $authenticated_fail_id, which is the username
+ provided to the authentication method which failed. It is available
+ for use in subsequent ACL processing (typically quit or notquit ACLs).
+
+23. New ACL modifer "udpsend" can construct a UDP packet to send to a given
+ UDP host and port.
+
+24. New ${hexquote:..string..} expansion operator converts non-printable
+ characters in the string to \xNN form.
+
+25. Experimental TPDA (Transport Post Delivery Action) function added.
+ Patch provided by Axel Rau.
+
+26. Experimental Redis lookup added. Patch provided by Warren Baker.
+
Version 4.80
------------
gnutls_require_mac & gnutls_require_protocols are no longer supported.
tls_require_ciphers is now parsed by gnutls_priority_init(3) as a priority
string, documentation for which is at:
- http://www.gnu.org/software/gnutls/manual/html_node/Priority-Strings.html
+ http://www.gnutls.org/manual/html_node/Priority-Strings.html
SNI support has been added to Exim's GnuTLS integration too.
