 Change log file for Exim from version 4.21
 -------------------------------------------
@@ -343,6 +343,38 @@ Exim version 4.50
     error if it is another Exim or anything else that does the synchronization
     check. A QUIT command is no longer sent after a timeout.
 
+73. $host_lookup_deferred has been added, to make it easier to detect DEFERs
+    during host lookups.
+
+74. The defer_ok option of callout verification was not working if it was used
+    when verifying addresses in header lines, that is, for this case:
+
+      verify = header_sender/callout=defer_ok
+
+75. A backgrounded daemon closed stdin/stdout/stderr on entry; this meant that
+    those file descriptors could be used for SMTP connections. If anything
+    wrote to stderr (the example that came up was "warn" in embedded Perl), it
+    could be sent to the SMTP client, causing chaos. The daemon now opens
+    stdin, stdout, and stderr to /dev/null when it puts itself into the
+    background.
+
+76. Arrange for output from Perl's "warn" command to be written to Exim's main
+    log by default. The user can override this with suitable Perl magic.
+
+77. The use of log_message on a "discard" ACL verb, which is supposed to add to
+    the log message when discard triggers, was not working for the DATA ACL or
+    for the non-SMTP ACL.
+
+78. Error message wording change in sieve.c.
+
+79. If smtp_accept_max_per_host was set, the number of connections could be
+    restricted to fewer than expected, because the daemon was trying to set up
+    a new connection before checking whether the processes handling previous
+    connections had finished. The check for completed processes is now done
+    earlier. On busy systems, this bug wouldn't be noticed because something
+    else would have woken the daemon, and it would have reaped the completed
+    process earlier.
