+PH/36 When a locally submitted message by a trusted user did not contain a
+ From: header, and the sender address was obtained from -f or from an SMTP
+ MAIL command, and the trusted user did not use -F to supply a sender
+ name, $originator_name was incorrectly used when constructing a From:
+ header. Furthermore, $originator_name was used for submission mode
+ messages from external hosts without From: headers in a similar way,
+ which is clearly wrong.
+
+PH/37 Added control=suppress_local_fixups.
+
+PH/38 When log_selector = +received_sender was set, and the addition of the
+ sender made the log line's construction buffer exactly full, or one byte
+ less than full, an overflow happened when the terminating "\n" was
+ subsequently added.
+
+PH/39 Added a new log selector, "unknown_in_list", which provokes a log entry
+ when the result of a list match is failure because a DNS lookup failed.
+
+PH/40 RM_COMMAND is now used in the building process.
+
+PH/41 Added a "distclean" target to the top-level Makefile; it deletes all
+ the "build-* directories that it finds.
+
+PH/42 (But a TF fix): In a domain list, Exim incorrectly matched @[] if the IP
+ address in a domain literal was a prefix of an interface address.
+
+PH/43 (Again a TF fix): In the dnslookup router, do not apply widen_domains
+ when verifying a sender address, unless rewrite_headers is false.
+
+PH/44 Wrote a long comment about why errors_to addresses are verified as
+ recipients, not senders.
+
+TF/01 Add missing LIBS=-lm to OS/Makefile-OpenBSD which was overlooked when
+ the ratelimit ACL was added.
+
+PH/45 Added $smtp_command for the full command (cf $smtp_command_argument).
+
+PH/46 Added extra information about PostgreSQL errors to the error string.
