Two new functions in the libnotmuch API:
`notmuch_message_count_files`, and `notmuch_thread_get_total_files`.
+New function to remove properties
+
+ A new function was added to the libnotmuch API to make it easier to
+ drop all properties with a common pattern:
+ `notmuch_message_remove_all_properties_with_prefix`
+
Change of return value of `notmuch_thread_get_authors`
In certain corner cases, `notmuch_thread_get_authors` previously
* Only error for invalid diff lines in `tags/`, which allows for
`README`s and similar in nmbug repositories.
+Documentation
+-------------
+
+New man page: notmuch-properties(7)
+
+ This new page to the manual describes common conventions for how
+ properties are used by libnotmuch, the CLI, and associated programs.
+ External projects that use properties are encouraged to claim their
+ properties and conventions here to avoid collisions.
