       This affected any platform not supporting "abstract" Unix-domain
       sockets (i.e. not Linux).
 
+JH/42 Bug 2693: Harden against a peer which reneges on a 452 "too many
+      recipients" response to RCPT in a later response, with a 250.  The
+      previous coding assumed this would not happen, and under PIPELINING
+      would result in both lost and duplicate recipients for a message.
+
+JH/43 Bug 2694: Fix weighted distribution of work to multiple spamd servers.
+      Previously the weighting was incorrectly applied.  Similar fix for socks
+      proxies.  Found and fixed by Heiko Schlichting.
+
+JH/44 Bug 2701: Fix list-expansion of dns_ipv4_lookup.  Previously, it did
+      not handle sub-lists included using the +namedlist syntax.  While
+      investigating, the same found for dns_trust_aa, dns_again_means_nonexist,
+      dnssec_require_domains, dnssec_request_domains, srv_fail_domains,
+      mx_fail_domains.
+
+JH/45 Use a (new) separate store pool-pair for DKIM verify working data.
+      Previously the permanent pool was used, so the sore could not be freed.
+      This meant a connection with many messages would use continually-growing
+      memory.
+
+JH/46 Use an exponentially-increasing block size when malloc'ing store.  Do it
+      per-pool so as not to waste too much space.  Previously a constant size
+      was used which resulted in O(n^2) behaviour; now we get O(n log n) making
+      DOS attacks harder.  The cost is wasted memory use in the larger blocks.
+
+JH/47 Use explicit alloc/free for DNS lookup workspace.  This permits using the
+      same space repeatedly, and a smaller process footprint.
+
+JH/48 Use a less bogus-looking filename for a temporary used for DH-parameters
+      for GnuTLS.  Previously the name started "%s" which, while not a bug,
+      looked as if if might be one.
+
+JH/49 Bug 2710: when using SOCKS for additional messages after the first (a
+      "continued connection") make the $proxy_* variables available.  Previously
+      the information was not passed across the exec() call for subsequent
+      transport executions.  This also mean that the log lines for the
+      messages can show the proxy information.
+
+JH/50 Bug 2672: QT elements in log lines, unless disabled, now exclude the 
+      receive time.  With modern systems the difference is significant.
+      The historical behaviour can be restored by disabling (a new) log_selector
+      "queue_time_exclusive".
