+Exim version 4.93
+-----------------
+
+JH/01 OpenSSL: With debug enabled output keying information sufficient, server
+      side, to decode a TLS 1.3 packet capture.
+
+JH/02 OpenSSL: Suppress the sending of (stateful) TLS1.3 session tickets.
+      Previously the default library behaviour applied, sending two, each in
+      its own TCP segment.
+
+JH/03 Debug output for ACL now gives the config file name and line number for
+      each verb.
+
+JH/04 The default received_header_text now uses the RFC 8314 tls cipher clause.
+
+JH/05 DKIM: ensure that dkim_domain elements are lowercased before use.
+
+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.

@@ -180,6 +215,20 @@ JH/39 OpenSSL: clear the error stack after an SSL_accept().  With anon-auth
       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".
