+Version 4.97
+------------
+
+ 1. The expansion-test facility (exim -be) can set variables.
+
+ 2. An event on a failing SMTP AUTH, for both client and server operations.
+
+ 3. Variable $sender_helo_verified with the result of an ACL "verify = helo".
+
+ 4. Predefined macros for expansion items, operators, conditions and variables.
+
+ 5. The smtp transport option "max_rcpt" is now expanded before use.
+
+ 6. The tls_eccurve option for OpenSSL now takes a list of group names.
+
+ 7. Queue runners for several queues can now be started from one daemon.
+
+ 8. New utility exim_msgdate converts message-ids to human readable format.
+
+ 9. An expansion operator for wrapping long header lines.
+
+ 10. A commandline option to print just the message IDs of the queue
+
+ 11. An option for the ${readsocket } expansion to set an SNI for TLS.
+
+ 12. The ACL remove_header modifier can take a pattern.
+
+ 13. Variable $recipients_list, a properly-quoted exim list.
+
+ 14. A log_selector for an incoming connection ID.
+
+Version 4.96
+------------
+
+ 1. A new ACL condition: seen. Records/tests a timestamp against a key.
+
+ 2. A variant of the "mask" expansion operator to give normalised IPv6.
+
+ 3. UTC output option for exim_dumpdb, exim_fixdb.
+
+ 4. An event for failing TLS connects to the daemon.
+
+ 5. The ACL "debug" control gains options "stop", "pretrigger" and "trigger".
+
+ 6. Query-style lookups are now checked for quoting, if the query string is
+    built using untrusted data ("tainted").  For now lack of quoting is merely
+    logged; a future release will upgrade this to an error.
+
+ 7. The expansion conditions match_<list-type> and inlist now set $value for
+    the expansion of the "true" result of the ${if}.  With a static list, this
+    can be used for de-tainting.
+
+ 8. Recipient verify callouts now set $domain_data & $local_part_data, with
+    de-tainted values.

+ 4. Single-key LMDB lookups, previously experimental, are now supported.
+    The support is not built unless specified in the Local/Makefile.
+
+ 5. Option "message_linelength_limit" on the smtp transport to enforce (by
+    default) the RFC 998 character limit.
+
+ 6. An option to ignore the cache on a lookup.
+
+ 7. Quota checking during reception (i.e. at SMTP time) for appendfile-
+    transport-managed quotas.
+
+ 8. Sqlite lookups accept a "file=<path>" option to specify a per-operation
+    db file, replacing the previous prefix to the SQL string (which had
+    issues when the SQL used tainted values).
+
+ 9. Lsearch lookups accept a "ret=full" option, to return both the portion
+    of the line matching the key, and the remainder.
+
+10. A command-line option to have a daemon not create a notifier socket.
+
+11. Faster TLS startup.  When various configuration options contain no
+    expandable elements, the information can be preloaded and cached rather
+    than the previous behaviour of always loading at startup time for every
+    connection.  This helps particularly for the CA bundle.
+
+12. Proxy Protocol Timeout is configurable via "proxy_protocol_timeout"
+    main config option.
+
+13. Option "smtp_accept_max_per_connection" is now expanded.
+
+14. Log selector "queue_time_exclusive", enabled by default, to exclude the
+    time taken for reception from QT log elements.
+
+15. Main option "smtp_backlog_monitor", to set a level above which listen
+    socket backlogs are logged.
+
+16. Main option "hosts_require_helo", requiring HELO or EHLO before MAIL.
+
+17. A main config option "allow_insecure_tainted_data" allows to turn
+
+18. TLS ALPN handling.  By default, refuse TLS connections that try to specify
+    a non-smtp (eg. http) use.  Options for customising.
+
+19. Support for MacOS (darwin) has been dropped.
