** Emacs interface(s) to notmuch
(notmuch-search "from:floris subject:cffi")
(notmuch-tree "from:floris subject:cffi")

#+RESULTS:

* What is new?
** Search Improvements
*** separate message body indexing
(notmuch-search "body:emacsconf and not subject:emacsconf")
*** user defined headers, e.g. =List-Id=
#+begin_src sh
notmuch config set header.List List-Id
notmuch reindex date:1month..
#+end_src

(notmuch-search "List:notmuch date:1month..")
** Cryptography Support
- (optional) indexing cleartext of encrypted e-mails
- (optional) caching of session keys

* What is next?
** notmuch-emacs improvements
- better docs?
- more asynch things
- convenience features, e.g. jump to parent messages
** Updating python bindings
- based on CFFI
- more /Pythonic/
- less broken with Python >= 3.6

** Protected Headers Support
