JH/03 Bug 425: Capture substrings in $regex1, $regex2 etc from regex &
mime_regex ACL conditions.
+JH/04 Bug 1686: When compiled with EXPERIMENTAL_DSN_INFO: Add extra information
+ to DSN fail messages (bounces): remote IP, remote greeting, remote response
+ to HELO, local diagnostic string.
+
+JH/05 Downgrade message for a TLS-certificate-based authentication fail from
+ log line to debug. Even when configured with a tls authenticator many
+ client connections are expected to not authenticate in this way, so
+ an authenticate fail is not an error.
+
+HS/02 Add the Exim version string to the process info. This way exiwhat
+ gives some more detail about the running daemon.
+
+JH/06 Bug 1395: time-limit cacheing of DNS lookups, to the TTL value. This may
+ matter for fast-change records such as DNSBLs.
+
+JH/07 Bug 1678: Always record an interface option value, if set, as part of a
+ retry record, even if constant. There may be multiple transports with
+ different interface settings and the retry behaviour needs to be kept
+ distinct.
+
+JH/08 Bug 1586: exiqgrep now refuses to run if there are unexpected arguments.
+
+JH/09 Bug 1700: ignore space & tab embedded in base64 during decode.
+
+JH/10 Bug 840: fix log_defer_output option of pipe transport
+
+JH/11 Bug 830: use same host for all RCPTS of a message, even under
+ hosts_randomize. This matters a lot when combined with mua_wrapper.
+
+JH/12 Bug 1706: percent and underbar characters are no longer escaped by the
+ ${quote_pgsql:<string>} operator.
+
+JH/13 Bug 1708: avoid misaligned access in cached lookup.
+
+JH/14 Change header file name for freeradius-client. Relevant if compiling
+ with Radius support; from the Gentoo tree and checked under Fedora.
+
+JH/15 Bug 1712: Introduce $prdr_requested flag variable
+
+JH/16 Bug 1714: Permit an empty string as expansion result for transport
+ option transport_filter, meaning no filtering.
+
+JH/17 Bug 1713: Fix non-PDKIM_DEBUG build. Patch from Jasen Betts.
+
+JH/18 Bug 1709: When built with TLS support, the tls_advertise_hosts option now
+ defaults to "*" (all hosts). The variable is now available when not built
+ with TLS, default unset, mainly to enable keeping the testuite sane.
+ If a server certificate is not supplied (via tls_certificate) an error is
+ logged, and clients will find TLS connections fail on startup. Presumably
+ they will retry in-clear.
+ Packagers of Exim are strongly encouraged to create a server certificate
+ at installation time.
+
+HS/03 Add -bP config_file as a synonym for -bP configure_file, for consistency
+ with the $config_file variable.
+
+JH/19 Two additional event types: msg:rcpt:defer and msg:rcpt:host:defer. Both
+ in transport context, after the attempt, and per-recipient. The latter type
+ is per host attempted. The event data is the error message, and the errno
+ information encodes the lookup type (A vs. MX) used for the (first) host,
+ and the trailing two digits of the smtp 4xx reponse.
+
+GF/01 Bug 1715: Fix for race condition in exicyclog, where exim could attempt
+ to write to mainlog (or rejectlog, paniclog) in the window between file
+ creation and permissions/ownership being changed. Particularly affects
+ installations where exicyclog is run as root, rather than exim user;
+ result is that the running daemon panics and dies.
+
Exim version 4.86
