-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.
+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

+JH/23 Performance improvement in the initial phase of a two-pass queue run.  By
+      running a limited number of proceses in parallel, a benefit is gained. The
+      amount varies with the platform hardware and load.  The use of the option
+      queue_run_in_order means we cannot do this, as ordering becomes
+      indeterminate.
+
+JH/24 Bug 2524: fix the cyrus_sasl auth driver gssapi usage.  A previous fix
+      had introduced a string-copy (for ensuring NUL-termination) which was not
+      appropriate for that case, which can include embedded NUL bytes in the
+      block of data.  Investigation showed the copy to actually be needless, the
+      data being length-specified.
+
+JH/25 Fix use of concurrent TLS connections under GnuTLS.  When a callout was
+      done during a receiving connection, and both used TLS, global info was
+      used rather than per-connection info for tracking the state of data
+      queued for transmission.  This could result in a connection hang.
+
+JH/26 Fix use of the SIZE parameter on MAIL commands, on continued connections.
+      Previously, when delivering serveral messages down a single connection
+      only the first would provide a SIZE.  This was due to the size information
+      not being properly tracked.
+
+JH/27 Bug 2530: When operating in a timezone with sub-minute offset, such as
+      TAI (at 37 seconds currently), pretend to be in UTC for time-related
+      expansion and logging.  Previously, spurious values such as a future
+      minute could be seen.
+
+JH/28 Bug 2533: Fix expansion of ${tr } item.  When called in some situations
+      it could crash from a null-deref.  This could also affect the
+      ${addresses: } operator and ${readsock } item.
+
+JH/29 Bug 2537: Fix $mime_part_count.  When a single connection had a non-mime
+      message following a mime one, the variable was not reset.
+
+JH/30 When an pipelined-connect fails at the first response, assume incorrect
+      cached capability (perhaps the peer reneged?) and immediately retry in
+      non-pipelined mode.
+
+JH/31 Fix spurious detection of timeout while writing to transport filter.
+
+JH/32 Bug 2541: Fix segfault on bad cmdline -f (sender) argument.  Previously
+      an attempt to copy the string was made before checking it.
+
+JH/33 Fix the dsearch lookup to return an untainted result.  Previously the
+      taint of the lookup key was maintained; we now regard the presence in the
+      filesystem as sufficient validation.
+
+JH/34 Fix the readsocket expansion to not segfault when an empty "options"
+      argument is supplied.
