+Version 4.91
+--------------
+
+ 1. Dual-certificate stacks on servers now support OCSP stapling, under GnuTLS
+    version 3.5.6 or later.
+
+ 2. DANE is now supported under GnuTLS version 3.0.0 or later (adding to the
+    previous OpenSSL implementation, but still Experimental).
+
+ 3. Feature macros for the compiled-in set of malware scanner interfaces.
+
+ 4. SPF support is promoted from Experimental to mainline status.  The template
+    src/EDITME makefile does not enable its inclusion.
+
+ 5. Logging control for DKIM verification.  The existing DKIM log line is
+    controlled by a "dkim_verbose" selector which is _not_ enabled by default.
+    A new tag "DKIM=<domain>" is added to <= lines by default, controlled by
+    a "dkim" log_selector.
+
+ 6. Receive duration on <= lines, under a new log_selector "receive_time".
+
+ 7. Options "ipv4_only" and "ipv4_prefer" on the dnslookup router and on
+    routing rules in the manualroute router.
+
+ 8. Expansion item ${sha3:<string>} / ${sha3_<N>:<string>} now also supported
+    under OpenSSL version 1.1.1 or later.
+
+ 9. DKIM operations can now use the Ed25519 algorithm in addition to RSA, under
+    GnuTLS 3.6.0 or later.
