+Notmuch 0.31 (2020-09-05)
+=========================
+
+Emacs
+-----
+
+Notmuch now supports Emacs 27.1. You may need to set
+`mml-secure-openpgp-sign-with-sender` and/or
+`mml-secure-smime-sign-with-sender` to continue signing messages.
+
+The minimum supported major version of GNU Emacs is now 25.1.
+
+Add support for moving between threads after notmuch-tree-from-search-thread.
+
+### New `notmuch-unthreaded` mode (added in Notmuch 0.30)
+
+Unthreaded view is a mode where each matching message is shown on a
+separate line.
+
+The main key entries to unthreaded view are
+
+'u' enter a query to view in unthreaded mode (works in hello,
+      search, show and tree mode)
+
+'U' view the current query in unthreaded mode (works from search,
+      show and tree)
+
+Saved searches can also specify that they should open in unthreaded
+view.
+
+Currently it is not possible to specify the sort order: it will
+always be newest first.
+
+Notmuch-Mutt
+------------
+
+The shell pipeline executed by notmuch-mutt, which symlinked matched
+files to a maildir for mutt to access is replaced with internal perl
+processing. This search operation is now more portable, and somewhat
+faster.
+
+Library
+-------
+
+Improve exception handling in the library. This should
+largely eliminate terminations inside the library due to uncaught
+exceptions or internal errors.  No doubt there are a few uncovered
+code paths still; please report them as bugs.
+
+Add `notmuch_message_get_flag_st` and
+`notmuch_message_has_maildir_flag_st`, and deprecate the existing
+non-status providing versions.
+
+Move memory de-allocation from `notmuch_database_close` to
+`notmuch_database_destroy`.
+
+Handle relative filenames in `notmuch_database_index_file`, as
+promised in the documentation.
+
+Python Bindings
+---------------
+
+Documentation for the python bindings is merged into the main
+sphinx-doc documentation tree. The merged documentation can be built
+with e.g. `make sphinx-html`
+
+Dependencies
+------------
+
+We now support building notmuch against Xapian 1.5 (the current
+development version).
+
+Test Suite
+----------
+
+Test suite fixes for compatibility with Emacs 27.1.
+
+Build System
+------------
+
+Man pages are now compressed reproducibly.
