@@ -218,6 +218,57 @@ JH/45 Use a (new) separate store pool-pair for DKIM verify working data.
       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".
+
+JH/51 Taint-check ACL line.  Previously, only filenames (for out-of-line ACL
+      content) were specifically tested for.  Now, also cover epxansions
+      rerulting in acl names and inline ACL content.
+
+JH/52 Fix ${ip6norm:} operator.  Previously, any trailing line text was dropped,
+      making it unusable in complex expressions.
+
+JH/53 Bug 2743: fix immediate-delivery via named queue.  Previously this would
+      fail with a taint-check on the spoolfile name, and leave the message
+      queued.
+
+HS/01 Enforce absolute PID file path name.
+
+HS/02 Handle SIGINT as we handle SIGTERM: terminate the Exim process.
+
+PP/01 Add a too-many-bad-recipients guard to the default config's RCPT ACL.
+
+PP/02 Bug 2643: Correct TLS DH constants.
+      A missing NUL termination in our code-generation tool had led to some
+      incorrect Diffie-Hellman constants in the Exim source.
+      Reported by kylon94, code-gen tool fix by Simon Arlott.
+
+PP/03 Fix Linux security issue CVE-2020-SLCWD and guard against PATH_MAX
+      better.  Reported by Qualys.
+
+PP/04 Impose security length checks on various command-line options.
+      Fixes CVE-2020-SPRSS reported by Qualys.
