+Version 4.97
+------------
+
+ 1. The expansion-test faciility (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.
+ 3. Variable $sender_helo_verified with the result of an ACL verify=helo.
+
+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.
+
Version 4.95
------------
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.

Version 4.94
------------
7. Named-list definitions can now be prefixed "hide" so that "-bP" commands do
not output the content. Previously this could only be done on options.
- 8. As an exerimental feature, the dovecot authentication driver supports inet
+ 8. As an experimental feature, the dovecot authentication driver supports inet
sockets. Previously it was unix-domain sockets only.
9. The ACL control "queue_only" can also be spelled "queue", and now takes an
