+Version 4.92
+--------------
+
+ 1. ${l_header:<name>} and ${l_h:<name>} expansion items, giving a colon-sep
+    list when there are multiple headers having a given name.  This matters
+    when individual headers are wrapped onto multiple lines; with previous
+    facilities hard to parse.
+
+ 2. The ${readsocket } expansion item now takes a "tls" option, doing the
+    obvious thing.
+
+ 3. EXPERIMENTAL_REQUIRETLS and EXPERIMENTAL_PIPE_CONNECT optional build
+    features.  See the experimental.spec file.
+
+ 4. If built with SUPPORT_I18N a "utf8_downconvert" option on the smtp transport.
+
+ 5. A "pipelining" log_selector.
+
+ 6. Builtin macros for supported log_selector and openssl_options values.
+
+ 7. JSON variants of the ${extract } expansion item.
+
+ 8. A "noutf8" debug option, for disabling the UTF-8 characters in debug output.
+
+ 9. TCP Fast Open support on MacOS.
+
+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.  Both GnuTLS and
+    OpenSSL versions are moved to mainline support from Experimental.
+    New SMTP transport option "dane_require_tls_ciphers".
+
+ 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 OpenSSL 1.1.1 or later.
+
+10. Builtin feature-macros _CRYPTO_HASH_SHA3 and _CRYPTO_SIGN_ED25519, library
+    version dependent.
+
+11. "exim -bP macro <name>" returns caller-usable status.
+
+12. Expansion item ${authresults {<machine>}} for creating an
+    Authentication-Results: header.
+
+13. EXPERIMENTAL_ARC.  See the experimental.spec file.
+    See also new util/renew-opendmarc-tlds.sh script for use with DMARC/ARC.
+
+14: A dane:fail event, intended to facilitate reporting.
+
+15. "Lightweight" support for Redis Cluster. Requires redis_servers list to
+    contain all the servers in the cluster, all of which must be reachable from
+    the running exim instance. If the cluster has master/slave replication, the
+    list must contain all the master and slave servers.
+
+16. Add an option to the Avast scanner interface: "pass_unscanned". This
+    allows to treat unscanned files as clean. Files may be unscanned for
+    several reasons: decompression bombs, broken archives.
