+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 a hybrid approach for checking.  Previously, one
+      of two ways was used, depending on a build-time flag.  The fast method
+      relied on assumptions about the OS and libc malloc, which were known to
+      not hold for the BSD-derived platforms, and discovered to not hold for
+      32-bit Linux either.  In fact the glibc documentation describes cases
+      where these assumptions do not hold.  The new implementation tests for
+      the situation arising and actively switches over from fast to safe mode.
