+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.

@@ -160,6 +187,40 @@ JH/34 Increase RSA keysize of autogen selfsign cert from 1024 to 2048.  RHEL 8.0
       more-modern GnuTLS move from GNUTLS_SEC_PARAM_LOW to
       GNUTLS_SEC_PARAM_MEDIUM.
 
+JH/35 OpenSSL: fail the handshake when SNI processing hits a problem, server
+      side.  Previously we would continue as if no SNI had been received.
+
+JH/36 Harden the handling of string-lists.  When a list consisted of a sole
+      "<" character, which should be a list-separator specification, we walked
+      off past the nul-terimation.
+
+JH/37 Bug 2341: Send "message delayed" warning MDNs (restricted to external
+      causes) even when the retry time is not yet met.  Previously they were
+      not, meaning that when (say) an account was over-quota and temp-rejecting,
+      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".
