has been dropped. The same can now be achieved more reliably using
out-of-tree builds.
+Command Line Interface
+----------------------
+
+Support for re-indexing existing messages
+
+ There is a new subcommand, `notmuch reindex`, which re-indexes all
+ messages matching supplied search terms. This permits users to
+ change the way specific messages are indexed.
+
+ Note that for messages with multiple variants in the message
+ archive, the recorded Subject: of may change upon reindexing,
+ depending on the order in which the variants are indexed.
+
Encrypted Mail
--------------
that the notmuch index itself is adequately protected. DO NOT USE
this feature without considering the security of your index.
+Library Changes
+---------------
+
+Indexing files with duplicate message-id
+
+ Files with duplicate message-id's are now indexed, and searchable
+ via terms and phrases. There are known issues related to
+ presentation of results and regular-expression search, but in
+ principle no mail file should be completely unsearchable now.
+
+New functions to count files
+
+ Two new functions in the libnotmuch API:
+ `notmuch_message_count_files`, and `notmuch_thread_get_total_files`.
+
+Change of return value of `notmuch_thread_get_authors`
+
+ In certain corner cases, `notmuch_thread_get_authors` previously
+ returned NULL. This has been replaced by an empty string, since the
+ possibility of NULL was not documented.
+
+nmbug
+-----
+
+nmbug's internal version increases to 0.3 in this notmuch release.
+User-facing changes with this notmuch release:
+
+* Accept failures to unset `core.worktree` in `clone`, which allows
+ nmbug to be used with Git 2.11.0 and later.
+* Auto-checkout in `clone` if it wouldn't clobber existing content,
+ which makes the initial clone more convenient.
+* Only error for invalid diff lines in `tags/`, which allows for
+ `README`s and similar in nmbug repositories.
