* 1.6 (released, as of July 27 2021)

*** mu

    - Where available (and with suitably equiped ~libglib~), log to the ~systemd~
      journal instead of ~~/.cache/mu.log~. Passing the ~--debug~ option to ~mu~
      increases the amount that is logged.

    - Follow symlinks in maildirs, and support moving messsages across
      filesystems. Obviously, that is typically quite a bit slower than the
      single-filesystem case, but can be still be useful.

    - Optionally provide readline support for the ~mu~ server (when in tty-mode)

    - Reworked the way mu generates s-expressions for mu4e; they are created
      programmatically now instead of through string building.

    - The indexer (the part of mu that scans maildirs and updates the message
      store) has been rewritten so it can work asynchronously and take advantage
      of multiple cores. Note that for now, indexing in ~mu4e~ is still a blocking
      operation.

    - Portability updates for dealing with non-POSIX systems, and in particular
      VFAT filesystem, and building using Clang/libc++.

    - The personal addresses (as per ~--my-address=~ for ~mu init~) can now also
      include regular expressions (basic POSIX); wrap the expression in ~/~, e.g.,
      ~--my-address='/.*@example.*/~'.

    - Modernized the querying/threading machinery; this makes some old code a
      lot easier to understand and maintain, and even while not an explicit
      goal, is also faster.

    - Experimental support for the Meson build system.

*** mu4e

    - Use the gnus-based message viewer as the default; the new viewer has quite
      a few extra features compared to the old, mu4e-specific one, such as
      faster crypto, support for S/MIME, syntax-highlighting, calendar
      invitations and more.

      The new view is superior in most ways, but if you still depend on
      something from the old one, you can use:
      #+begin_example
      ;; set *before* loading mu4e; and restart emacs if you want to change it
      ;; users of use-packag~ should can use the :init section for this.
      (setq mu4e-view-use-old t)
      #+end_example

      (The older variable ~mu4e-view-use-gnus~ with the opposite meaning is
      obsolete now, and no longer in use).

    - Include maildir-shortcuts in the main-view with overall/unread counts,
      similar to bookmarks, and with the same ~:hide~ and ~:hide-unread~ properties.
      Note that for the latter, you need to update your maildir-shortcuts to the
      new format, as explained in the ~mu4e-maildir-shortcuts~ docstring.

      You can set ~mu4e-main-hide-fully-read~ to hide any bookmarks/maildirs that
      have no unread messages.

    - Add some more properties for use in capturing org-mode links to messages /
      queries. See [[info:mu4e#Org-mode links][the mu4e manual]] for details.

    - Honor ~truncate-string-ellipsis~ so you can now use 'fancy' ellipses for
      truncated strings with ~(setq truncate-string-ellipsis "…")~

    - Add a variable ~mu4e-mu-debug~ which, when set to non-~nil,~ makes the ~mu~
      server log more verbosely (to ~mu.log~ or the journal)

    - Better alignment in headers-buffers; this looks nicer, but is also a bit
      slower, hence you need to enable ~mu4e-headers-precise-alignment~ for this.

    - Support ~mu~'s new regexp-based personal addresses, and add
      ~mu4e-personal-address-p~ to check whether a given string matches a personal
      address.

    - TAB-Completion for writing ~mu~ queries

    - Switch the context for existing draft messages using
      ~mu4e-compose-context-switch~ or ~C-c C-;~ in ~mu4e-compose-mode~.
