+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/10 Bug 2223: Fix mysql lookup returns for the no-data case (when the number of
+ rows affected is given instead).
+
+JH/11 The runtime Berkeley DB library version is now additionally output by
+ "exim -d -bV". Previously only the compile-time version was shown.
+
+JH/12 Bug 2230: Fix cutthrough routing for nonfirst messages in an initiating
+ SMTP connection. Previously, when one had more receipients than the
+ first, an abortive onward connection was made. Move to full support for
+ multiple onward connections in sequence, handling cutthrough connection
+ for all multi-message initiating connections.
+
+JH/13 Bug 2229: Fix cutthrough routing for nonstandard port numbers defined by
+ routers. Previously, a multi-recipient message would fail to match the
+ onward-connection opened for the first recipient, and cause its closure.
+
+JH/14 Bug 2174: A timeout on connect for a callout was also erroneously seen as
+ a timeout on read on a GnuTLS initiating connection, resulting in the
+ initiating connection being dropped. This mattered most when the callout
+ was marked defer_ok. Fix to keep the two timeout-detection methods
+ separate.
+
+JH/15 Relax results from ACL control request to enable cutthrough, in
+ unsupported situations, from error to silently (except under debug)
+ ignoring. This covers use with PRDR, frozen messages, queue-only and
+ fake-reject.
+
+HS/01 Fix Buffer overflow in base64d() (CVE-2018-6789)
+
+JH/16 Fix bug in DKIM verify: a buffer overflow could corrupt the malloc
+ metadata, resulting in a crash in free().
+
+PP/01 Fix broken Heimdal GSSAPI authenticator integration.
+ Broken in f2ed27cf5, missing an equals sign for specified-initialisers.
+ Broken also in d185889f4, with init system revamp.
+
+JH/17 Bug 2113: Fix conversation closedown with the Avast malware scanner.
+ Previously we abruptly closed the connection after reading a malware-
+ found indication; now we go on to read the "scan ok" response line,
+ and send a quit.
+
+JH/18 Bug 2239: Enforce non-usability of control=utf8_downconvert in the mail
+ ACL. Previously, a crash would result.
+
+JH/19 Speed up macro lookups during configuration file read, by skipping non-
+ macro text after a replacement (previously it was only once per line) and
+ by skipping builtin macros when searching for an uppercase lead character.
+
+JH/20 DANE support moved from Experimental to mainline. The Makefile control
+ for the build is renamed.
+
+JH/21 Fix memory leak during multi-message connections using STARTTLS. A buffer
+ was allocated for every new TLS startup, meaning one per message. Fix
+ by only allocating once (OpenSSL) or freeing on TLS-close (GnuTLS).
+
+JH/22 Bug 2236: When a DKIM verification result is overridden by ACL, DMARC
+ reported the original. Fix to report (as far as possible) the ACL
+ result replacing the original.
+
+JH/23 Fix memory leak during multi-message connections using STARTTLS under
+ OpenSSL. Certificate information is loaded for every new TLS startup,
+ and the resources needed to be freed.
+
+JH/24 Bug 2242: Fix exim_dbmbuild to permit directoryless filenames.
+
+JH/25 Fix utf8_downconvert propagation through a redirect router. Previously it
+ was not propagated.
+
+JH/26 Bug 2253: For logging delivery lines under PRDR, append the overall
+ DATA response info to the (existing) per-recipient response info for
+ the "C=" log element. It can have useful tracking info from the
+ destination system. Patch from Simon Arlott.
+
+JH/27 Bug 2251: Fix ldap lookups that return a single attribute having zero-
+ length value. Previously this would segfault.
+
+HS/02 Support Avast multiline protoocol, this allows passing flags to
+ newer versions of the scanner.
+
+JH/28 Ensure that variables possibly set during message acceptance are marked
+ dead before release of memory in the daemon loop. This stops complaints
+ about them when the debug_store option is enabled. Discovered specifically
+ for sender_rate_period, but applies to a whole set of variables.
+ Do the same for the queue-runner loop, for variables set from spool
+ message files.
+
+PP/02 DANE: add dane_require_tls_ciphers SMTP Transport option; if unset,
+ tls_require_ciphers is used as before.
+
+JH/34 Re-introduce enforcement of no cutthrough delivery on transports having
+ transport-filters or DKIM-signing. The restriction was lost in the
+ consolidation of verify-callout and delivery SMTP handling.
+ Extend the restriction to also cover ARC-signing.
