+JH/08 Bug 3056: Tighten up parsing of DKIM DNS records. Previously, whitespace
+ was not properly skipped and empty elements would cause mis-parsing.
+ Tighten parsing of DKIM header records. Previously, all but lowercase
+ alpha chars would be ignored in potential tag names.
+
+JH/09 Bug 3057: Add heuristic for spotting mistyped IPv6 addresses in lists
+ being searched. Previously we only had one for IPv4 addresses. Per the
+ documentation, the error results by default in a no-match result for the
+ list. It is logged if the unknown_in_list log_selector is used.
+
+JH/10 Bug 3058: Ensure that a failing expansion in a router "set" option defers
+ the routing operation. Previously it would silently stop routing the
+ message.
+
+JH/11 Bug 3046: Fix queue-runs. Previously, the arrivel of a notification or
+ info-request event close in time to a scheduled run timer could result in
+ the latter being missed, and no further queue scheduled runs being
+ initiated. This ouwld be more likely on high-load systems.
+
+JH/12 Refuse to accept a line "dot, LF" as end-of-DATA unless operating in
+ LF-only mode (as detected from the first header line). Previously we did
+ accept that in (normal) CRLF mode; this has been raised as a possible
+ attack scenario (under the name "smtp smuggling").
+
+JH/13 Add an fdatasync call for the received message data file in spool, before
+ loggging reception and sending the SMTP ack. Previously we only flushed
+ the stdio buffer so there was still the possibility of a disk error.
+
+JH/14 Bug 3061: Avoid a split log line when trtying to rewrite a malformed
+ address. Previously, for the last address in a header line (commonly
+ there is only one) the terminating newline was part of the logged
+ information.
