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".
