2.4.0 (2026-06-19):

  ! Maildir folders are now only recognized if they contain cur, new, and tmp
    subfolders.  Previously mutt only checked for the cur subfolder when
    opening.
  ! --without-wc-funcs configure option is deprecated.
  + New functions <open-thread>, <open-all-threads>, <close-thread>,
    <close-all-threads> were added to explicitly open/close a thread, in
    addition to the thread toggle functions.
  + $tmpdraftdir, defaulting /var/tmp, sets the directory where message
    composition drafts are saved.
  ! --textmode is no longer required for pgp classic mode signing, although
    mutt still keeps the flags in the sample config files.
  ! ~C and ~L patterns match Bcc recipient lists too.
  ! When querying for addresses, via <query> or <complete-query>,
    the query menu can be exiting via <quit> after tagging entries.
    Previously, <select-entry> had to be used for tagged entries to be
    processed.
  ! Classic S/MIME now generates application/pkcs7-mime and
    application/pkcs7-signature types instead of the deprecated
    x-pkcs7-mime and x-pkcs7-signature types.
  ! Saving attachments will sanitize filenames by substituting '_' for '/'.
  ! Regular expression handling when searching in the pager has been
    improved slightly.  (REG_NEWLINE mode has been turned off, and
    newlines are excluded from searches).  This means searches such
    as /^$ now work properly.
  ! When compiled with OpenSSL, Mutt follows RFC6125, and does not match
    against CN entries in the certificate if there are any DNS entries.
