+TK/03 Fix log output including CR from clamd.
+
+PH/14 A reference to $reply_address when Reply-to: was empty and From: did not
+ exist provoked a memory error which could cause a segfault.
+
+PH/15 Installed PCRE 6.2
+
+PH/17 Defined BIND_8_COMPAT in the Darwin os.h file.
+
+PH/18 Reversed 4.52/PH/17 because the HP-UX user found it wasn't the cause
+ of the problem. Specifically, suggested +O2 rather than +O1 for the
+ HP-UX compiler.
+
+PH/19 Added sqlite_lock_timeout option (David Woodhouse's patch).
+
+PH/20 If a delivery was routed to a non-standard port by means of an SRV
+ record, the port was not correctly logged when the outgoing_port log
+ selector was set (it logged the transort's default port).
