+- If a message body contains 8-bit bytes, post(8) uses SMTP 8BITMIME if the
+ server supports it. If not, post fails with a message to the user to
+ encode the message for 7-bit transport.
+- Added welcome message when nmh detects that its version changed.
+- Fewer lseek(2)s will be used when reading headers in the common case.
+- Single-character headers can be reliably formatted, etc., instead of
+ apparently being missing.
+- ./configure's --enable-debug has been removed; it did nothing.
