+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.
+
+JH/20 Bug 1701: For MySQL lookups, support MySQL config file option group names.
+
+JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
+ selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options
+ "pri" and "weight". Note that the previous implicit priority given by the
+ list order is no longer honoured.
+
+JH/22 Bugs 963, 1721: Fix some corner cases in message body canonicalisation
+ for DKIM processing.
+
+JH/23 Move SOCKS5 support from Experimental to mainline. It can be left out
+ from a build by defining DISABLE_SOCKS.
