+Exim version 4.93
+-----------------
+
+JH/01 GnuTLS: repeat lowlevel read and write operations while they return error
+      codes indicating retry.  Under TLS1.3 this becomes required.

@@ -142,6 +149,44 @@ JH/30 Bug 2329: Increase buffer size used for dns lookup from 2k, which was
       the way to the max DNS message size of 64kB, even though this might be
       overmuch for IOT constrained device use.
 
+JH/31 Fix a bad use of a copy function, which could be used to pointlessly
+      copy a string over itself.  The library routine is documented as not
+      supporting overlapping copies, and on MacOS it actually raised a SIGABRT.
+
+JH/32 For main options check_spool_space and check_inode_space, where the
+      platform supports 64b integers, support more than the previous 2^31 kB
+      (i.e. more than 2 TB).  Accept E, P and T multipliers in addition to
+      the previous G, M, k.
+
+JH/33 Bug 2338: Fix the cyrus-sasl authenticator to fill in the
+      $authenticated_fail_id variable on authentication failure.  Previously
+      it was unset.
+
+JH/34 Increase RSA keysize of autogen selfsign cert from 1024 to 2048.  RHEL 8.0
+      OpenSSL didn't want to use such a weak key.  Do for GnuTLS also, and for
+      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.
