+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 expansions
+ resulting 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 Qualys.
+ 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.
+
+JH/59 DKIM: Fix small-message verification under TLS with chunking. If a
+ pipelined SMTP command followed the BDAT LAST then it would be
+ incorrectly treated as part of the message body, causing a verification
+ fail.
