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.
