@@ -32,9 +32,65 @@ JH/07 GnuTLS: Our use of late (post-handshake) certificate verification, under
       TLS connection attempt, so that the normal retry-in-clear can work (if
       suitably configured).
 
-JB/01 Big 2375: fix expansions of 822 addresses having comments in local-part
+JB/01 Bug 2375: fix expansions of 822 addresses having comments in local-part
       and/or domain.  Found and fixed by Jason Betts.
 
+JH/08 Add hardening against SRV & TLSA lookups the hit CNAMEs (a nonvalid
+      configuration).  If a CNAME target was not a wellformed name pattern, a
+      crash could result.
+
+JH/09 Logging: Fix initial listening-on line for multiple ports for an IP when
+      the OS reports them interleaved with other addresses.
+
+JH/10 OpenSSL: Fix aggregation of messages.  Previously, when PIPELINING was
+      used both for input and for a verify callout, both encrypted, SMTP
+      responses being sent by the server could be lost.  This resulted in
+      dropped connections and sometimes bounces generated by a peer sending
+      to this system.
+
+JH/11 Harden plaintext authenticator against a badly misconfigured client-send
+      string.  Previously it was possible to cause undefined behaviour in a
+      library routine (usually a crash).  Found by "zerons".
+
+JH/12 Bug 2384: fix "-bP smtp_receive_timeout".  Previously it returned no
+      output.
+
+JH/13 Bug 2386: Fix builds with Dane under LibreSSL 2.9.0 onward.  Some old
+      API was removed, so update to use the newer ones.
+
+JH/14 Bug 1891: Close the log file if receiving a non-smtp message, without
+      any timeout set, is taking a long time.  Previously we would hang on to a
+      rotated logfile "forever" if the input was arriving with long gaps
+      (a previous attempt to fix addressed lack, for a long time, of initial
+      input).
+
+HS/01 Bug 2390: Use message_id for tempfile creation to avoid races in a
+      shared (NFS) environment. The length of the tempfile name is now
+      4 + 16 ("hdr.$message_exim_id") which might break on file
+      systems which restrict the file name length to lower values.
+      (It was "hdr.$pid".)
+
+HS/01 Bug 2390: Use message_id for tempfile creation to avoid races in a
+      shared (NFS) environment.
+
+HS/02 Bug 2392: exigrep does case sensitive *option* processing (as it
+      did for all versions <4.90). Notably -M, -m, --invert, -I may be
+      affected.
+
+JH/15 Use unsigned when creating bitmasks in macros, to avoid build errors
+      on some platforms for bit 31.
+
+JH/16 GnuTLS: rework ciphersuite strings under recent library versions.  Thanks
+      to changes apparently associated with TLS1.3 handling some of the APIs
+      previously used were either nonfunctional or inappropriate.  Strings
+      like TLS1.3:ECDHE_SECP256R1__RSA_PSS_RSAE_SHA256__AES_256_GCM__AEAD:256
+      and TLS1.2:ECDHE_SECP256R1__RSA_SHA256__AES_128_CBC__SHA256:128 replace
+      the previous TLS1.2:ECDHE_RSA_AES_256_GCM_SHA384:256 .
+      This affects log line X= elements, the $tls_{in,out}_cipher variables,
+      and the use of specific cipher names in the encrypted= ACL condition.
+
+JH/17 OpenSSL: the default openssl_options now disables ssl_v3.
