+Version 4.97
+------------
+
+ 1. The expansion-test faciility (exim -be) can set variables.
+
+ 2. An event on a failing SMTP AUTH, server side.
+
+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.
