@@ -218,6 +218,115 @@ 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 Impose security length checks on various command-line options.
+      Fixes CVE-2020-SPRSS reported by Qualys.
+
+PP/04 Fix Linux security issue CVE-2020-SLCWD and guard against PATH_MAX
+      better.  Reported by Qualys.
+
+PP/05 Fix security issue CVE-2020-PFPSN and guard against cmdline invoker
+      providing a particularly obnoxious sender full name.
+      Reported by Qualys.
+
+PP/06 Fix CVE-2020-28016 (PFPZA): Heap out-of-bounds write in parse_fix_phrase()
+
+PP/07 Refuse to allocate too little memory, block negative/zero allocations.
+      Security guard.
+
+PP/08 Change default for recipients_max from unlimited to 50,000.
+
+PP/09 Fix security issue with too many recipients on a message (to remove a
+      known security problem if someone does set recipients_max to unlimited,
+      or if local additions add to the recipient list).
+      Fixes CVE-2020-RCPTL reported by Qualys.
+
+PP/10 Fix security issue in SMTP verb option parsing
+      Fixes CVE-2020-EXOPT reported by Qualys.
+
+PP/11 Fix security issue in BDAT state confusion.
+      Ensure we reset known-good where we know we need to not be reading BDAT
+      data, as a general case fix, and move the places where we switch to BDAT
+      mode until after various protocol state checks.
+      Fixes CVE-2020-BDATA reported by Qualys.
+
+HS/03 Die on "/../" in msglog file names
+
+QS/01 Creation of (database) files in $spool_dir: only uid=0 or the uid of
+      the Exim runtime user are allowed to create files.
+
+QS/02 PID file creation/deletion: only possible if uid=0 or uid is the Exim
+      runtime user.
+
+QS/03 When reading the output from interpreted forward files we do not
+      pass the pipe between the parent and the interpreting process to
+      executed child processes (if any).
+
+QS/04 Always die if requested from internal logging, even is logging is
+      disabled.
+
+JH/54 DMARC: recent versions of the OpenDMARC library appear to have broken
+      the API; compilation noo longer completes with DMARC support included.
+      This affects 1.4.1-1 on Fedora 33 (1.3.2-3 is functional); and has
+      been reported on other platforms.
+
+JH/55 TLS: as server, reject connections with ALPN indicating non-smtp use.
+
+JH/56 Make the majority of info read from config files readonly, for defence-in-
+      depth against exploits.  Suggestion by Qualsy.
+      Not supported on Solaris 10.
+
+JH/57 Fix control=fakreject for a custom message containing tainted data.
+      Previously this resulted in a log complaint, due to a re-expansion present
+      since fakereject was originally introduced.
+
+JH/58 GnuTLS: Fix certextract expansion.  If a second modifier after a tag
+      modifier was given, a loop resulted.
