+Handle S/MIME signatures in emacs
+
+ The emacs interface is now capable making and verifying S/MIME
+ signatures.
+
+`notmuch-message-address-insinuate` is now a no-op
+
+ This reduces the amount of interference with non-notmuch uses of
+ message-mode.
+
+Address completion improvements
+
+ An external script is no longer needed for address completion; if
+ you previously configured one, customize the variable
+ `notmuch-address-command` to try the internal completion. If
+ `company-mode` is available, notmuch uses it by default for
+ interactive address completion.
+
+Test and experiment with the emacs MUA available in source tree
+
+ `./devel/try-emacs-mua` runs emacs and fills the window with
+ information how to try the MUA safely. Emacs is configured to use
+ the notmuch (lisp) files located in `./emacs` directory.
