[PATCH] NEWS: NEWS for 0.28

[David Bremner]

This is based on my subjective assessment of what is user/packager
facing and important from the output of 'git shortlog'
---

I squashed all the news patches together since there were no other
contributions. I will release with these notes pretty soon, so please
send any fixes ASAP.

 Notmuch 0.28 (UNRELEASED)
 =========================
 
+General
+-------
+
+Improve threading
+
+  The threading algorithm has been updated to consider all references,
+  not just the heuristically chosen parent (e.g. when that parent is
+  not in the database). The heuristic for choosing a parent message
+  has also been updated to again consider the In-Reply-To header, if
+  it looks sensible. Re-indexing might be needed to take advantage of
+  the latter change.
+
+Handle mislabeled Windows-1252 parts
+
+  Messages that contain Windows-1252 are apparently frequently
+  mislabeled as ISO 8859-1. Use GMime functionality to apply the
+  correct encoding for such messages.
+
+Command Line Interface
+----------------------
+
+Support relative database paths
+
+  Database paths (i.e. parameters to `notmuch config set
+  database.path`) without a leading `/` are now interpreted relative
+  to $HOME of the invoking user.
+
+Emacs
+-----
+
+Fix stderr handling on e.g. macOS
+
+  Add a real sentinal process to clean up stderr buffer.
+
+Call `notmuch-mua-send-hook` hooks when sending a message
+
+  This hook was documented, but not functional for a very long time.
+
+Completion
+----------
+
+The zsh completion has been updated to cover most of the notmuch
+CLI. Internally it uses regexp searching, so needs at least Notmuch
+0.24.
+
+Build System
+------------
+
+The build system now installs notmuch-mutt and notmuch-emacs-mua with
+absolute shebangs, following the conventions of most Linux
+distributions.
+
+Test Suite
+----------
+
+Fix certain tests that were failing with GMime 2.6. Users are reminded
+that support for versions of GMime before 3.0.3 has been deprecated
+since Notmuch 0.25.
+
