+JH/21 Bug 1720: Add support for priority groups and weighted-random proxy
+ selection for the EXPERIMENTAL_SOCKS feature, via new per-proxy options

+ 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, enabled for a build
+ by defining SUPPORT_SOCKS.
+
+JH/26 Move PROXY support from Experimental to mainline, enabled for a build
+ by defining SUPPORT_PROXY. Note that the proxy_required_hosts option
+ is renamed to hosts_proxy, and the proxy_{host,target}_{address,port}.
+ variables are renamed to proxy_{local,external}_{address,port}.
+
+JH/27 Move Internationalisation support from Experimental to mainline, enabled
+ for a build by defining SUPPORT_I18N
+
+JH/28 Bug 1745: Fix redis lookups to handle (quoted) spaces embedded in parts
+ of the query string, and make ${quote_redis:} do that quoting.
+

+ keys are given for lookup.
+
+JH/34 Bug 1192: replace the embedded copy of PolarSSL RSA routines in the DKIM
+ support, by using OpenSSL or GnuTLS library ones. This means DKIM is
+ only supported when built with TLS support.
+
+JH/35 Require SINGLE_DH_USE by default in OpenSSL (main config option
+ openssl_options), for security. OpenSSL forces this from version 1.1.0
+ server-side so match that on older versions.
