+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.

+ 6. The reproducible build $SOURCE_DATE_EPOCH environment variable is now
+    supported.
+
+ 7. Optionally, an alternate format for spool data-files which matches the
+    wire format - meaning more efficient reception and transmission (at the
+    cost of difficulty with standard Unix tools).  Only used for messages
+    received using the ESMTP CHUNKING option, and when a new main-section
+    option "spool_wireformat" (false by default) is set.
+
+ 8. New main configuration option "commandline_checks_require_admin" to
+    restrict who can use various introspection options.
+
+ 9. New option modifier "no_check" for quota and quota_filecount
+    appendfile transport.
+
+10. Variable $smtp_command_history returning a comma-sep list of recent
+    SMTP commands.
+
+11. Millisecond timetamps in logs, on log_selector "millisec".  Also affects
+    log elements QT, DT and D, and timstamps in debug output.
+
+12. TCP Fast Open logging.  As a server, logs when the SMTP banner was sent
+    while still in SYN_RECV state; as a client logs when the connection
+    is opened with a TFO cookie.
+
+13. DKIM support for multiple signing, by domain and/or key-selector.
+    DKIM support for multiple hashes, and for alternate-identity tags.
+    Builtin macro with default list of signed headers.
+    Better syntax for specifying oversigning.
+    The DKIM ACL can override verification status, and status is visible in
+    the data ACL.
+
+14. Exipick understands -C|--config for an alternative Exim
+    configuration file.
+
+15. TCP Fast Open used, with data-on-SYN, for client SMTP via SOCKS5 proxy,
+    for ${readsocket } expansions, and for ClamAV.
+
+16. The "-be" expansion test mode now supports macros.  Macros are expanded
+    in test lines, and new macros can be defined.
+
+17. Support for server-side dual-certificate-stacks (eg. RSA + ECDSA).
