+PH/58 Allow for the insertion of a newline as well as a space when a string
+ is turned into more than one encoded-word during RFC 2047 encoding. The
+ Sieve code now uses this.
+
+PH/59 Added the following errors that can be detected in retry rules: mail_4xx,
+ data_4xx, lost_connection, tls_required.
+
+PH/60 When a VRFY deferred or FAILED, the log message rather than the user
+ message was being sent as an SMTP response.
+
+PH/61 Add -l and -k options to exicyclog.
+
+PH/62 When verifying, if an address was redirected to one new address, so that
+ verification continued, and the new address failed or deferred after
+ having set something in $address_data, the value of $address_data was not
+ passed back to the ACL. This was different to the case when no
+ redirection occurred. The value is now passed back in both cases.
+
+PH/63 Changed the macro HAVE_LOGIN_CAP (see PH/41 for this release above) to
+ HAVE_SETCLASSRESOURCES because there are different APIs in use that all
+ use login_cap.h, so on its own it isn't the distinguishing feature. The
+ new name refers directly to the setclassresources() function.
+
+PH/65 Added configuration files for NetBSD3.
+
+PH/66 Updated OS/Makefile-HP-UX for gcc 4.1.0 with HP-UX 11.
+
+PH/67 Fixed minor infelicity in the sorting of addresses to ensure that IPv6
+ is preferred over IPv4.
