+Exim version 4.91
+-----------------
+
+JH/01 Replace the store_release() internal interface with store_newblock(),
+      which internalises the check required to safely use the old one, plus
+      the allocate and data copy operations duplicated in both (!) of the
+      extant use locations.
+
+JH/02 Disallow '/' characters in queue names specified for the "queue=" ACL
+      modifier.  This matches the restriction on the commandline.
+
+JH/03 Fix pgsql lookup for multiple result-tuples with a single column.
+      Previously only the last row was returned.
+
+JH/04 Bug 2217: Tighten up the parsing of DKIM signature headers. Previously
+      we assumed that tags in the header were well-formed, and parsed the
+      element content after inspecting only the first char of the tag.
+      Assumptions at that stage could crash the receive process on malformed
+      input.
+
+JH/05 Bug 2215: Fix crash associated with dnsdb lookup done from DKIM ACL.
+      While running the DKIM ACL we operate on the Permanent memory pool so that
+      variables created with "set" persist to the DATA ACL.  Also (at any time)
+      DNS lookups that fail create cache records using the Permanent pool.  But
+      expansions release any allocations made on the current pool - so a dnsdb
+      lookup expansion done in the DKIM ACL releases the memory used for the
+      DNS negative-cache, and bad things result.  Solution is to switch to the
+      Main pool for expansions.
+      While we're in that code, add checks on the DNS cache during store_reset,
+      active in the testsuite.
+      Problem spotted, and debugging aided, by Wolfgang Breyha.
+
+JH/06 Fix issue with continued-connections when the DNS shifts unreliably.
+      When none of the hosts presented to a transport match an already-open
+      connection, close it and proceed with the list.  Previously we would
+      queue the message.  Spotted by Lena with Yahoo, probably involving
+      round-robin DNS.
+
+JH/07 Bug 2214: Fix SMTP responses resulting from non-accept result of MIME ACL.
+      Previously a spurious "250 OK id=" response was appended to the proper
+      failure response.
+
+JH/08 The "support for" informational output now, which built with Content
+      Scanning support, has a line for the malware scanner interfaces compiled
+      in.  Interface can be individually included or not at build time.
+
+JH/09 The "aveserver", "kavdaemon" and "mksd" interfaces are now not included
+      by the template makefile "src/EDITME".  The "STREAM" support for an older
+      ClamAV interface method is removed.

+JH/27 Fix SOCKS bug: an unitialized pointer was deref'd by the transport process
+      which could crash as a result.  This could lead to undeliverable messages.
+
+JH/28 Logging: "next input sent too soon" now shows where input was truncated
+      for log purposes.
+
+JH/29 Fix queue_run_in_order to ignore the PID portion of the message ID.  This
+      matters on fast-turnover and PID-randomising systems, which were getting
+      out-of-order delivery.
+
+JH/30 Fix a logging bug on aarch64: an unsafe routine was previously used for
+      a possibly-overlapping copy.  The symptom was that "Remote host closed
+      connection in response to HELO" was logged instead of the actual 4xx
+      error for the HELO.
+
+JH/31 Fix CHUNKING code to properly flush the unwanted chunk after an error.
+      Previously only that bufferd was discarded, resulting in SYMTP command
+      desynchronisation.
+
+JH/32 DKIM: when a message has multiple signatures matching an identity given
+      in dkim_verify_signers, run the dkim acl once for each.  Previously only
+      one run was done.  Bug 2189.
+
+JH/33 Downgrade an unfound-list name (usually a typo in the config file) from
+      "panic the current process" to "deliberately defer".  The panic log is
+      still written with the problem list name; the mail and reject logs now
+      get a temp-reject line for the message that was being handled, saying
+      something like "domains check lookup or other defer".  The SMTP 451
+      message is still "Temporary local problem".
+
+JH/34 Bug 2199: Fix a use-after-free while reading smtp input for header lines.
+      A crafted sequence of BDAT commands could result in in-use memory beeing
+      freed.  CVE-2017-16943.
+
+HS/03 Bug 2201: Fix checking for leading-dot on a line during headers reading
+      from SMTP input.  Previously it was always done; now only done for DATA
+      and not BDAT commands.  CVE-2017-16944.
+
+JH/35 Bug 2201: Flush received data in BDAT mode after detecting an error fatal
+      to the message (such as an overlong header line).  Previously this was
+      not done and we did not exit BDAT mode.  Followon from the previous item
+      though a different problem.
