+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.
+
+JH/04 Remove the docs and support scripts dealing with conversion of Exim
+ version 3 installations.

+Exim version 4.98
