+JH/15 When PIPELINING, synch after every hundred or so RCPT commands sent and
+      check for 452 responses.  This slightly helps the inefficieny of doing
+      a large alias-expansion into a recipient-limited target.  The max_rcpt
+      transport option still applies (and at the current default, will override
+      the new feature).  The check is done for either cause of synch, and forces
+      a fast-retry of all 452'd recipients using a new MAIL FROM on the same
+      connection.  The new facility is not tunable at this time.
+
+JH/16 Fix the variables set by the gsasl authenticator.  Previously a pointer to
+      library live data was being used, so the results became garbage.  Make
+      copies while it is still usable.
+
+JH/17 Logging: when the deliver_time selector ise set, include the DT= field
+      on delivery deferred (==) and failed (**) lines (if a delivery was
+      attemtped).  Previously it was only on completion (=>) lines.
+
+JH/18 Authentication: the gsasl driver not provides the $authN variables in time
+      for the expansion of the server_scram_iter and server_scram_salt options.
+
+WB/01 SPF: DNS lookups for the obsolete SPF RR type done by the libspf2 library
+      are now specifically given a NO_DATA response without hitting the system
+      resolver.  The library goes on to do the now-standard TXT lookup.
+      Use of dnsdb lookups is not affected.
+
+JH/19 Bug 2507: Modules: on handling a dynamic-module (lookups) open failure,
+      only retrieve the errormessage once.  Previously two calls to dlerror()
+      were used, and the second one (for mainlog/paniclog) retrieved null
+      information.
+
+JH/20 Taint checking: disallow use of tainted data for
+      - the appendfile transport file and directory options
+      - the pipe transport command
+      - the autoreply transport file, log and once options
+      - file names used by the redirect router (including filter files)
+      - named-queue names
+      Previously this was permitted.
+
+JH/21 Bug 2501: Fix init call in the heimdal authenticator.  Previously it
+      adjusted the size of a major service buffer; this failed because the
+      buffer was in use at the time.  Change to a compile-time increase in the
+      buffer size, when this authenticator is compiled into exim.
+
+JH/22 Taint-checking: move to safe-mode taint checking on all platforms.  The
+      previous fast-mode was untenable in the face of glibs using mmap to
+      support larger malloc requests.
+
+PP/01 Update the openssl_options possible values through OpenSSL 1.1.1c.
+      New values supported, if defined on system where compiled:
+      allow_no_dhe_kex, cryptopro_tlsext_bug, enable_middlebox_compat,
+      no_anti_replay, no_encrypt_then_mac, prioritize_chacha, tlsext_padding
+
