 Exim version 4.98
 -----------------
 
+JH/01 Use fewer forks & execs for sending many messages to a single host.
+      By passing back more info from the transport to the delivery process,
+      we can loop there.  A two-phase queue run will benefit, particularly for
+      mailinglist and smarthost cases.
+
+JH/02 Add transaction support for hintsdbs. The providers supported are tdb and
+      sqlite. Transactions are used for the wait-transport and retry DBs.
+      They imply locking internal to the DB.  We no longer need a separate
+      lockfile, can keep the DB handle open for extended periods, yet
+      potentially benefit from concurrency on non-conflicting record uses.
+
+JH/03 With dkim_verify_minimal, avoid calling the DKIM ACL after the first
+      good verify.
+
+Exim version 4.98
+-----------------
+
 JH/01 Support list of dkim results in the dkim_status ACL condition, making
       it more usable in the data ACL.
