+PH/04 Applied Magnus Holmgren's patch to fix Bugzilla #98: transport's home
+ directory not expanded when it should be if an expanded home directory
+ was set for the address (which is overridden by the transport).
+
+PH/05 Applied Alex Kiernan's patch to fix Bugzilla #99: a problem with
+ libradius.
+
+PH/06 Added acl_not_smtp_start, based on Johannes Berg's patch, and set the
+ bit to forbid control=suppress_local_fixups in the acl_not_smtp ACL,
+ because it is too late at that time, and has no effect.
+
+PH/07 Changed ${quote_pgsql to quote ' as '' instead of \' because of a
+ security issue with \' (bugzilla #107). I could not use the
+ PQescapeStringConn() function, because it needs a PGconn value as one of
+ its arguments.
+
+PH/08 When testing addresses using -bt, indicate those final addresses that
+ are duplicates that would not cause an additional delivery. At least one
+ person was confused, thinking that -bt output corresponded to deliveries.
+ (Suppressing duplicates isn't a good idea as you lose the information
+ about possibly different redirections that led to the duplicates.)
+
+PH/09 Applied patch from Erik to use select() instead of poll() in spam.c on
+ systems where poll() doesn't work, in particular OS X.
+
+PH/10 Added more information to debugging output for retry time not reached.
