  1. PKG_CONFIG_PATH can now be set in Local/Makefile;
     wildcards will be expanded, values are collapsed.
 
+ 2. The ${readsocket } expansion now takes an option to not shutdown the
+    connection after sending the query string.  The default remains to do so.
+
+ 3. An smtp transport option "hosts_noproxy_tls" to control whether multiple
+    deliveries on a single TCP connection can maintain a TLS connection
+    open.  By default disabled for all hosts, doing so saves the cost of
+    making new TLS sessions, at the cost of having to proxy the data via
+    another process.  Logging is also affected.
+
+ 4. A malware connection type for the FPSCAND protocol.
+
+ 5. An option for recipient verify callouts to hold the connection open for
+    further recipients and for delivery.
+
+ 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.  Support varies between platforms
+    (Linux does both. FreeBSD server only, others unknown).
+
+13. DKIM support for multiple signing, by domain and/or key-selector.
+    DKIM support for multiple hashes.

 Version 4.89
 ------------
 
  1. Allow relative config file names for ".include"
 
+ 2. A main-section config option "debug_store" to control the checks on
+    variable locations during store-reset.  Normally false but can be enabled
+    when a memory corrution issue is suspected on a production system.
