JH/10 Bug 2223: Fix mysql lookup returns for the no-data case (when the number of
rows affected is given instead).
+JH/12 Bug 2230: Fix cutthrough routing for nonfirst messages in an initiating
+ SMTP connection. Previously, when one had more receipients than the
+ first, an abortive onward connection was made. Move to full support for
+ multiple onward connections in sequence, handling cutthrough connection
+ for all multi-message initiating connections.
+
+JH/13 Bug 2229: Fix cutthrough routing for nonstandard port numbers defined by
+ routers. Previously, a multi-recipient message would fail to match the
+ onward-connection opened for the first recipient, and cause its closure.
+
+JH/14 Bug 2174: A timeout on connect for a callout was also erroneously seen as
+ a timeout on read on a GnuTLS initiating connection, resulting in the
+ initiating connection being dropped. This mattered most when the callout
+ was marked defer_ok. Fix to keep the two timeout-detection methods
+ separate.
+
+JH/16 Fix bug in DKIM verify: a buffer overflow could corrupt the malloc
+ metadata, resulting in a crash in free().
+
+PP/01 Fix broken Heimdal GSSAPI authenticator integration.
+ Broken in f2ed27cf5, missing an equals sign for specified-initialisers.
+ Broken also in d185889f4, with init system revamp.
