[Exim] missing envelope-to after update

Hello,

I was running 3.33 and updated to 3.34. Same configuration file. No
problem it seems. Business as usual. Except for one thing: Exim does no
longer add the Envelope-To header.

These are the transports:

   mailman_transport:
     driver = pipe
     command = MAILMAN_WRAP \
               '${if def:local_part_suffix \
                     {${sg{$local_part_suffix}{-(\\w+)(\\+.*)?}{\$1}}} \
                     {post}}' \
               $local_part
     current_directory = MAILMAN_HOME
     home_directory = MAILMAN_HOME
     user = mailman
     group = mail

   procmail_pipe:
     driver = pipe
     check_string = "From "
     command = "/usr/bin/procmail -d ${local_part}"
     delivery_date_add
     envelope_to_add
     escape_string = ">From "
     group = mail
     return_path_add
     user = $local_part

   local_delivery:
     driver = appendfile
     file = /var/mail/$local_part
     delivery_date_add
     envelope_to_add
     return_path_add

   address_pipe:
     driver = pipe
     return_output
     envelope_to_add

   address_file:
     driver = appendfile
     delivery_date_add
     envelope_to_add
     return_path_add

   address_reply:
     driver = autoreply

It says "envelope_to_add" which, to my knowledge, would cause that header
to be added. Any idea why it is missing?
