       Pollution of logs was the major effect, as the other process delivered

+JH/29 Change format of the internal ID used for message identification. The old
+      version only supported 31 bits for a PID element; the new 64 (on systems
+      which can use Base-62 encoding, which is all currently supported ones
+      but not Darwin (MacOS) or Cygwin, which have case-insensitive filesystems
+      and must use Base-36).  The new ID is 23 characters rather than 16, and is
+      visible in various places - notably logs, message headers, and spool file
+      names.  Various of the ancillary utilities also have to know the format.
+	As well as the expanded PID portion, the sub-second part of the time
+      recorded in the ID is expanded to support finer precision.  Theoretically
+      this permits a receive rate from a single comms channel of better than the
+      previous 2000/sec.
+        The major timestamp part of the ID is not changed; at 6 characters it is
+      usable until about year 3700.
+        Updating from previously releases is fully supported: old-format spool
+      files are still usable, and the utilities support both formats.  New
+      message will use the new format.  The one hints-DB file type which uses
+      message-IDs (the transport wait- DB) will be discarded if an old-format ID
+      is seen; new ones will be built with only new-format IDs.
+      Optionally, a utility can be used to convert spool files from old to new,
+      but this is only an efficiency measure not a requirement for operation
+        Downgrading from new to old requires running a provided utility, having
+      first stopped all operations.  This will convert any spool files from new
+      back to old (losing time-precision and PID information) and remove any
+      wait- hints databases.

+JH/30 Bug 3006: Fix handling of JSON strings having embedded commas. Previously
+      we treated them as item separators when parsing for a list item, but they
+      need to be protected by the doublequotes.  While there, add handling for
+      backslashes.
+
+JH/31 Bug 2998: Fix ${utf8clean:...} to disallow UTF-16 surrogate codepoints.
+      Found and fixed by Jasen Betts. No testcase for this as my usual text
+      editor insists on emitting only valid UTF-8.
+
+JH/32 Fix "tls_dhparam = none" under GnuTLS.  At least with 3.7.9 this gave
+      a null-indirection SIGSEGV for the receive process.
+
+JH/33 Fix free for live variable $value created by a ${run ...} expansion during
+      -bh use.  Internal checking would spot this and take a panic.

+JH/34 Bug 3013: Fix use of $recipients within arguments for ${run...}.

+
+JH/37 Bug 3016: Avoid sending DSN when message was accepted under fakereject
+      or fakedefer.  Previously the sender could discover that the message
+      had in fact been accepted.
+
+JH/38 Taint-track intermediate values from the peer in multi-stage authentation
+      sequences.  Previously the input was not noted as being tainted; notably
+      this resulted in behaviour of LOGIN vs. PLAIN being inconsistent under
