 New Features in Exim

+      The SQLite library handles multiple simultaneous accesses to the database
+      internally. Multiple readers are permitted, but only one process can
+      update at once. Attempts to access the database while it is being updated
+      are rejected after a timeout period, during which the SQLite library
+      waits for the lock to be released. In Exim, the default timeout is set
+      to 5 seconds, but it can be changed by means of the sqlite_lock_timeout
+      option.

       Note that you must set LOOKUP_SQLITE=yes in Local/Makefile in order to
       obtain SQLite support, and you will also need to add -lsqlite3 to the
       EXTRALIBS setting. And of course, you have to install SQLite on your

       not happened, "verify = helo" does it there and then.
 
+PH/06 It is now possible to specify a port number along with a host name or
+      IP address in the list of hosts defined in the manualroute or
+      queryprogram routers, fallback_hosts, or the "hosts" option of the smtp
+      transport. These all override any port specification on the transport.
+      The relatively standard syntax of using a colon separator has been
+      adopted, but there are some gotchas that need attention:
+
+      * In all these lists of hosts, colon is the default separator, so either
+        the colon that specifies a port must be doubled, or the separator must
+        be changed. The following two examples have the same effect:
+
+          fallback_hosts = host1.tld::1225 : host2.tld::1226
+          fallback_hosts = <; host1.tld:1225 ; host2.tld:1226
+
+      * When IPv6 addresses are involved, it gets worse, because they contain
+        colons of their own. To make this case easier, it is permitted to
+        enclose an IP address (either v4 or v6) in square brackets if a port
+        number follows. Here's an example from a manualroute router:
+
+           route_list = * "</ [10.1.1.1]:1225 / [::1]:1226"
+
+      If the "/MX" feature is to be used as well as a port specifier, the port
+      must come last. For example:
+
+           route_list = *  dom1.tld/mx::1225
+
+PH/07 $smtp_command_argument is now set for all SMTP commands, not just the
+      non-message ones. This makes it possible to inspect the complete command
+      for RCPT commands, for example.
+
+PH/08 The ${eval expansion now supports % as a "remainder" operator.
