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.
