NEWS (user visible changes)


After a decade of development, mu 1.0!

Note: the new release requires a C++14 capable compiler.


  • New, custom query parser which replaces Xapian’s ‘QueryParser’ both in mu and mu4e. Existing queries should still work, but the new engine handles non-alphanumeric queries much better.
  • Support regular expressions in queries (with the new query engine), e.g. “subject:/foo.*bar/”. See the new `mu-query` and updated `mu-easy` manpages for examples.
  • cfind: ensure nicks are unique
  • auxiliary programs invoked from mu/mu4e survive terminating the shell / emacs


  • Allow for rewriting message bodies
  • Toggle-menus for header settings
  • electric-quote-(local-)mode work when composing emails
  • Respect format=flowed and delsp=yes for viewing plain-text messages
  • Added new mu4e-split-view mode: single-window
  • Add menu item for `untrash’.
  • Unbreak abbrevs in mu4e-compose-mode
  • Allow forwarding messages as attachments (`mu4e-compose-forward-as-attachment’)
  • New defaults: default to ‘skip duplicates’ and ‘include related’ in headers-view, which should be good defaults for most users. Can be customized using `mu4e-headers-skip-duplicates’ and `mu4e-headers-include-related’, respectively.
  • Many bug fixed (see github for all the details).
  • Updated documentation

And all the people on the mailing-list and in github, with bug reports, questions and suggestions.


New development series which will lead to 0.9.18.


  • Increase the default maximum size for messages to index to 500 Mb; you can customize this using the –max-msg-size parameter to mu index.
  • implement “lazy-checking”, which makes mu not descend into subdirectories when the directory-timestamp is up to date; greatly speeds up indexing (see –lazy-check)
  • prefer gpg2 for crypto
  • fix a crash when running on OpenBSD
  • fix –clear-links (broken filenames)
  • You can now set the MU_HOME environment variable as an alternative way of setting the mu homedir via the –muhome commadn-line parameter.


reading messages

  • Add `mu4e-action-view-with-xwidget`, and action for viewing e-mails inside a Webkit-widget inside emacs (requires emacs 25.x with xwidget/webkit/gtk3 support)
  • Explicitly specify utf8 for external html viewing, so browsers can handle it correctly.
  • Make `shr’ the default renderer for rich-text emails (when available)
  • Add a :user-agent field to the message-sexp (in mu4e-view), which is either the User-Agent or X-Mailer field, when present.

composing messages

  • Cleanly handle early exits from message composition as well as while composing.
  • Allow for resending existing messages, possibly editing them. M-x mu4e-compose-resend, or use the menu; no shortcut.
  • Better handle the closing of separate compose frames
  • Improved font-locking for the compose buffers, and more extensive checks for cited parts.
  • automatically sign/encrypt replies to signed/encrypted messages (subject to `mu4e-compose-crypto-reply-policy’)

searching & marking

  • Add a hook `mu4e-mark-execute-pre-hook`, which is run just before executing marks.
  • Just before executing any search, a hook-function `mu4e-headers-search-hook` is invoked, which receives the search expression as its parameter.
  • In addition, there’s a `mu4e-headers-search-bookmark-hook` which gets called when searches get invoked as a bookmark (note that `mu4e-headers-search-hook` will also be called just afterwards). This hook also receives the search expression as its parameter.
  • Remove the ‘z’ keybinding for leaving the headers view. Keybindings are precious!
  • Fix parentheses/precedence in narrowing search terms


  • Allow for indexing in the background; see `mu4e-index-update-in-background`.
  • Better handle mbsync output in the update buffer
  • Add variables mu4e-index-cleanup and mu4e-index-lazy to enable lazy checking from mu4e; you can sit from mu4e using something like:
  mu4e-index-cleanup nil      ;; don't do a full cleanup check
  mu4e-index-lazy-check t)    ;; don't consider up-to-date dirs


  • don’t overwrite global-mode-string, append to it.
  • Make org-links (and more general, all users of mu4e-view-message-with-message-id) use a headers buffer, then view the message. This way, those linked message are just like any other, and can be deleted, moved etc.
  • Support org-mode 9.x
  • Improve file-name escaping, and make it support non-ascii filenames
  • Attempt to jump to the same messages after a re-search update operation
  • Add action for spam-filter options
  • Let `mu4e~read-char-choice’ become case-insensitive if there is no exact match; small convenience that affects most the single-char option-reading in mu4e.


  • an experimental Perl binding (“mup”) is available now. See perl/ for details.

Old news



2016-01-20: Release from the 0.9.15 series

(and of course all people who reported issues, provided suggestions etc.)


  • bump version to 0.9.15. From now on, odd minor version numbers are for development versions; thus, 0.9.16 is to be the next stable release.
  • special case text/calendar attachements to get .vcs extensions. This makes it easier to process those with external tools.
  • change the message file names to better conform to the maildir spec; this was confusing some tools.
  • fix navigation when not running in split-view mode
  • add `mu4e-view-body-face’, so the body-face for message in the view can be customized; e.g. (set-face-attribute ‘mu4e-view-body-face nil :font “Liberation Serif-10”)
  • add `mu4e-action-show-thread`, an action for the headers and view buffers to search for messages in the same thread as the current one.
  • allow for transforming mailing-list names for display, using `mu4e-mailing-list-patterns’.
  • some optimizations in indexing (~30% faster in some cases)
  • new variable mu4e-user-agent-string, to customize the User-Agent: header.
  • when removing the “In-reply-to” header from replies, mu4e will also remove the (hidden) References header, effectively creating a new message-thread.
  • implement ‘mu4e-context’, for defining and switching between various contexts, which are groups of settings. This can be used for instance for switch between e-mail accounts. See the section in the manual for details.
  • correctly decode mailing-list headers
  • allow for “fancy” mark-characters; and improve the default set
  • by default, the maildirs are no longer cached; please see the variable mu4e-cache-maildir-list if you have a lot of maildirs and it gets slow.
  • change the default value for org-mu4e-link-query-in-headers-mode to nil, ie. by default link to the message, not the query, as this is usually more useful behavior.
  • overwrite target message files that already exist, rather than erroring out.
  • set mu4e-view-html-plaintext-ratio-heuristic to 5, as 10 was too high to detect some effectively html-only messages
  • add mu4e-view-toggle-html (keybinding: ‘h’) to toggle between text and html display. The existing ‘mu4e-view-toggle-hide-cited’ gets the new binding ‘#’.
  • add a customization variable `mu4e-view-auto-mark-as-read’ (defaults to t); if set to nil, mu4e won’t mark messages as read when you open them. This can be useful on read-only file-systems, since marking-as-read implies a file-move operation.
  • use smaller chunks for mu server on Cygwin, allowing for better mu4e support there.

(and of course all people who reported issues, provided suggestions etc.)


  • NEWS (this file) is now visible from within mu4e – “N” in the main-menu.
  • make `mu4e-headers-sort-field’, `mu4e-headers-sort-direction’ public (that, is change the prefix from mu4e~ to mu4e-), so users can manipulate them
  • make it possible the ‘fancy’ (unicode) characters separately for headers and marks (see the variable `mu4e-use-fancy-chars’.)
  • allow for composing in a separate frame (see `mu4e-compose-in-new-frame’)
  • add the `:thread-subject’ header field, for showing the subject for a thread only once. So, instead of (from the manual):

    This is a feature known from e.g. `mutt’ and `gnus` and many other clients, and can be enabled by customizing `mu4e-headers-fields’ (replacing `:subject’ with `:thread-subject’)

    It’s not the default yet, but may become so in the future.

  • add some spam-handling actions to mu4e-contrib.el

  • many bug fixes, including some crash fixes on BSD


– add –delete option to the find-dups scripts, to automatically delete them. Use with care!
