 New Features in Exim
 --------------------
@@ -8,6 +8,51 @@ but have not yet made it into the main manual (which is most conveniently
 updated when there is a relatively large batch of changes). The doc/ChangeLog
 file contains a listing of all changes, including bug fixes.
 
+Exim version 4.53
+-----------------
+
+TK/01 Added the "success_on_redirect" address verification option. When an
+      address generates new addresses during routing, Exim will abort
+      verification with "success" when more than one address has been
+      generated, but continue to verify a single new address. The latter
+      does not happen when the new "success_on_redirect" option is set, like
+
+      require verify = recipient/success_on_redirect/callout=10s
+
+      In that case, verification will succeed when a router generates a new
+      address.
+
+PH/01 Support for SQLite database lookups has been added. This is another
+      query-style lookup, but it is slightly different from the others because
+      a file name is required in addition to the SQL query. This is because an
+      SQLite database is a single file and there is no daemon as in other SQL
+      databases. The interface to Exim requires the name of the file, as an
+      absolute path, to be given at the start of the query. It is separated
+      from the query by white space. This means that the path name cannot
+      contain white space. Here is a lookup expansion example:
+
+        ${lookup sqlite {/some/thing/sqlitedb \
+          select name from aliases where id='ph10';}}
+
+      In a list, the syntax is similar. For example:
+
+        domainlist relay_domains = sqlite;/some/thing/sqlitedb \
+           select * from relays where ip='$sender_host_address';
+
+      The only character affected by the ${quote_sqlite: operator is a single
+      quote, which it doubles.
+
+      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
+      host first.
+
+PH/02 The variable $message_id is now deprecated, to be replaced by
+      $message_exim_id, which makes it clearer which ID is being referenced.
+
+PH/03 The use of forbid_filter_existstest now also locks out the use of the
+      ${stat: expansion item.

 Exim version 4.52

       example, you can limit the sending rate of each authenticated user,
       independent of the computer they are sending from, by setting the key
       to $authenticated_id. The default key is $sender_host_address.
+      Internally, Exim includes the smoothing constant p and the options in
+      the lookup key because they alter the meaning of the stored data.
+      This is not true for the limit m, so you can alter the configured
+      maximum rate and Exim will still remember clients' past behaviour,
+      but if you alter the other ratelimit parameters Exim will effectively
+      forget their past behaviour.
 
       Each ratelimit condition can have up to two options. The first option
       specifies what Exim measures the rate of, and the second specifies how
