mu
╌╌

  • mu now defaults to the [XDG Base Directory Specification] for the
    default locations for various files. E.g. on Unix the mu database
    now lives under `~/.cache/mu/' rather than `~/.mu'. You can still
    use the old location by passing `--muhome=~/.mu' to various `mu'
    commands, or setting `(setq mu4e-mu-home "~/.mu")' for `mu4e'.

    If your `~/.cache' is volatile (e.g., is cleared on reboot), you may
    want use `--muhome'. Some mailing-list dicussion suggest that's
    fairly rare though.

    After upgrading, you may wish to delete the files in the old
    location to recover some diskspace.


  • There's a new subcommand `mu init' to initialize the mu database,
    which takes the `--maildir' and `--my-address' parameters that
    `index' used to take. These parameters are persistent so `index'
    does not need (or accept) them anymore. `mu4e' now depends on those
    parameters.

    `init' only needs to be run once or when changing these parameters.
    That implies that you need to re-index after changing these
    parameters.

  • There is another new subcommand `mu info' to get information about
    the mu database, the personal addresses etc.

  • The contacts cache (which is used by `mu cfind' and `mu4e''s
    contact-completion) is now stored as part of the Xapian database
    rather than as a separate file.

  • The `--xbatchsize' and `--autoupgrade' options for indexing are gone
    now; both are determined implicitly now.

mu4e
╌╌╌╌

  • `mu4e' no longer uses the `mu4e-maildir' and
    `mu4e-user-mail-address-list' variables; instead it uses the
    information it gets from `mu' (see the `mu' section above).

    It is strongly recommended that you run `mu init' with the
    appropriate parameters to (re)initialize the Xapian database, as
    mentioned in the mu-section above.

    The main screen shows your address(es), and issues a warning if
    `user-email-address' is not part of that (and refer you to `mu
    init'). You can avoid the addresses in the main screen and the
    warning by setting `mu4e-main-view-hide-addresses' to non-nil.

  • In many cases, `mu4e' used to receive /all/ contacts after each
    indexing operation; this was slow for some users, so we have updated
    this to /only/ get the contacts that have changed since the last
    round.

    We also moved sorting the contacts to the mu-side, which speeds
    things up further. However, as a side-effect of this,
    `mu4e-contacts-rewrite-function' and
    `mu4e-compose-complete-ignore-address-regexp' have been obsoleted;
    users of those should migrate to `mu4e-contact-process-function';
    see its docstring for details.

  • Christophe Troestler contributed support for Gnus'
    calender-invitation handling in mu4e (i.e., you should be able to
    accept/reject invitations etc.). It's very fresh code, and likely
    it'll be tweaked in the future. But it's available now for testing.
    Note that this requires the gnus-based viewer, as per `(setq
    mu4e-view-use-gnus t)'

  • In addition, he added support for custom headers, so the ones for
    for the non-gnus-view should work just as well.

  • Pierre Neidhardt contributed an experimental "Account Setup Helper"
    which wraps the existing context setup with some niceties for
    accounts. See the manual for details.

  • `org-mode' support is enabled by default now. `speedbar' support is
    disabled by default.

  • `mu4e' now adds message-ids to messages when saving drafts, so we
    can find them even with `mu4e-headers-skip-duplicates'.

  • Bookmarks (as in `mu4e-bookmarks') are now simple plists (instead of
    cl structs). `make-mu4e-bookmark' has been updated to produce such
    plists (for backward compatibility). A bookmark now looks like a
    list of e.g. `(:name "My bookmark" :query "banana OR pear" :key ?f)'
    this format is a bit easier extensible.

  • `mu4e' recognizes an attribute `:hide t', which will hide the
    bookmark item from the main-screen (and speedbar), but keep it
    avilable through the completion UI.

  • `mu4e-maildir-shortcuts' have also become plists. The older format
    is still recognized for backward compatibility, but you are
    encouraged to upgrade.

  • Replying to mailing-lists has been improved, allowing for choosing
    for replying to all, sender, list-only.

  • A very visible change, `mu4e' now shows unread/all counts for
    bookmarks in the main screen. This is on by default, but can be
    disabled by setting `:hide-unread' in the bookmark `plist' to `t'.
    For speed-reasons, these counts do _not_ filter out duplicates or
    messages that have been removed from the filesystem behind mu4e's
    back.

  • `mu4e-attachment-dir' now also applies to composing messages; it
    determines the default directory for inclusion.

  • The mu4e <-> mu interaction has been rewritten to communicate using
    s-expressions, with a repl for testing. If you have readline
    installed, you also get history.


toys
╌╌╌╌

  • Updated the `mug' toy UI to use Webkit2/GTK+. Note that this is just
    a toy which is not meant for distribution. `msg2pdf' is disabled for
    now.
