+PH/26 Added a "continue" ACL modifier that does nothing, for the benefit of its
+ expansion side effects.
+
+PH/27 When a message times out after an over-quota error from an Exim-imposed
+ quota, the bounce message says "mailbox is full". This message was not
+ being given when it was a system quota that was exceeded. It now should
+ be the same.
+
+MH/03 Made $recipients available in local_scan(). local_scan() already has
+ better access to the recipient list through recipients_list[], but
+ $recipients can be useful in postmaster-provided expansion strings.
+
+PH/28 The $smtp_command and $smtp_command_argument variables were not correct
+ in the case of a MAIL command with additional options following the
+ address, for example: MAIL FROM:<foo@bar> SIZE=1234. The option settings
+ were accidentally chopped off.
