+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.
+
+Notmuch 0.27 (2018-06-13)
+=========================
+
+General
+-------
+
+Add support for thread:{} queries
+
+ Queries of the form `thread:{foo} and thread:{bar}` match threads
+ containing (possibly distinct) messages matching foo and bar. See
+ `notmuch-search-terms(7)` for details.
+
+Command Line Interface
+----------------------
+
+Add the --full-scan option to `notmuch new`
+
+ This option disables mtime based optimization of scanning for new mail.
+
+Add new --decrypt=stash option for `notmuch show`
+
+ This facilitates a workflow for encrypted messages where message
+ cleartext are indexed on first read, but the user's decryption key
+ does not have to be available during message receipt.
+
+Documentation
+-------------
+
+An initial manual for `notmuch-emacs` is now installed by default (in
+`info` format).
+
+Dependencies
+------------
+
+As of this release, support for versions of Xapian before 1.4.0 is
+deprecated, and may disappear in a future release of notmuch.
+
+Notmuch 0.26.2 (2018-04-28)
+===========================
+
+Library Changes
+---------------
+
+Work around Xapian bug with `get_mset(0,0, x)`
+
+ This causes aborts in `_notmuch_query_count_documents` on
+ e.g. Fedora 28. The underlying bug is fixed in Xapian commit
+ f92e2a936c1592, and will be fixed in Xapian 1.4.6.
+
+Make thread indexing more robust against reference loops
+
+ Choose a thread root by date in case of reference loops. Fix a
+ related abort in `notmuch show`.
+
+Notmuch 0.26.1 (2018-04-02)
+===========================
+
+Library Changes
+---------------
+
+Bump the library minor version. This should have happened in 0.26, but
+better late than never.
