+Exim version 4.92.1
+-------------------
+
+JH/31 Avoid re-expansion in ${sort } expansion. (CVE-2019-13917, OVE-20190718-0006)
+
+
+Since version 4.92
+------------------
+
+JH/06 Fix buggy handling of autoreply bounce_return_size_limit, and a possible
+      buffer overrun for (non-chunking) other transports.
+
+JH/07 GnuTLS: Our use of late (post-handshake) certificate verification, under
+      TLS1.3, means that a server rejecting a client certificate is not visible
+      to the client until the first read of encrypted data (typically the
+      response to EHLO).  Add detection for that case and treat it as a failed
+      TLS connection attempt, so that the normal retry-in-clear can work (if
+      suitably configured).
+
+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/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/18 GnuTLS: fix $tls_out_ocsp under hosts_request_ocsp. Previously the
+      verification result was not updated unless hosts_require_ocsp applied.
+
+JH/19 Bug 2398: fix listing of a named-queue.  Previously, even with the option
+      queue_list_requires_admin set to false, non-admin users were denied the
+      facility.
+
+JH/20 Bug 2389: fix server advertising of usable certificates, under GnuTLS in
+      directory-of-certs mode.  Previously they were advertised despite the
+      documentation.
+
+JH/27 Bug 2404: Use the main-section configuration option "dsn_from" for
+      success-DSN messages.  Previously the From: header was always the default
+      one for these; the option was ignored.
+
+PP/01 Unbreak heimdal_gssapi, broken in 4.92.

       and multiple senders' messages were queued, only one sender would get
       notified on each configured delay_warning cycle.
 
+JH/38 Bug 2351: Log failures to extract envelope addresses from message headers.
+
+JH/39 OpenSSL: clear the error stack after an SSL_accept().  With anon-auth
+      cipher-suites, an error can be left on the stack even for a succeeding
+      accept; this results in impossible error messages when a later operation
+      actually does fail.
+
+AM/01 Bug 2359: GnuTLS: repeat lowlevel read and write operations while they
+      return error codes indicating retry.  Under TLS1.3 this becomes required.
+
+JH/40 Fix the feature-cache refresh for EXPERIMENTAL_PIPE_CONNECT.  Previously
+      it only wrote the new authenticators, resulting in a lack of tracking of
+      peer changes of ESMTP extensions until the next cache flush.
+
+JH/41 Fix the loop reading a message header line to check for integer overflow,
+      and more-often against header_maxsize.  Previously a crafted message could
+      induce a crash of the recive process; now the message is cleanly rejected.
+
+JH/42 Bug 2366: Fix the behaviour of the dkim_verify_signers option.  It had
+      been totally disabled for all of 4.91.  Discovery and fix by "Mad Alex".
