+ Enabled utf-8 mailbox support for IMAP.
+ New expandos %r and %R for comma separated list of To: and Cc:
recipients respectively.
+ Improved support for internationalized email and SMTPUTF8 (RFC653[0-3]).
! $use_idn has been renamed to $idn_decode.
+ $idn_encode controls whether outgoing email address domains will
be IDNA encoded. If your MTA supports it, unset to use utf-8
email address domains.
+ The S/MIME message digest algorithm is now specified using the
option $smime_sign_digest_alg. Note that $smime_sign_command
should be modified to include "-md %d". Please see
contrib/smime.rc.
+ $reflow_space_quotes allows format=flowed email quotes to be
displayed with spacing between them.
! multipart draft files are now supported.
+ The "-E" command line argument causes mutt to edit draft or include files.
All changes made in mutt will be saved back out to those files.
+ $resume_draft_files and $resume_edited_draft_files control how
mutt processes draft files.
+ For classic gpg mode, $pgp_decryption_okay should be set to verify
multipart/encrypted are actually encrypted. Please see
contrib/gpg.rc for the suggested value.
! mailto URL header parameters by default are now restricted to
'body' and 'subject'.
+ mailto_allow and unmailto_allow can be used to add or remove
allowed mailto header parameters.
! The method of setting $hostname has been changed. Rather than
scanning /etc/resolv.conf, the domain will now be determined using
DNS calls.
