+Notmuch 0.15 (YYYY-MM-DD)
+=========================
+
+Command-Line Interface
+----------------------
+
+Empty tag names and tags beginning with "-" are deprecated
+
+ Such tags have been a frequent source of confusion and cause
+ (sometimes unresolvable) conflicts with other syntax. notmuch tag
+ no longer allows such tags to be added to messages. Removing such
+ tags continues to be supported to allow cleanup of existing tags,
+ but may be removed in a future release.
+
+Bcc and Reply-To headers are now available in notmuch show json output
+
+ The `notmuch show --format=json` now includes "Bcc" and "Reply-To" headers.
+ For example notmuch Emacs client can now have these headers visible
+ when the headers are added to the `notmuch-message-headers` variable.
+
+Library changes
+---------------
+
+Date range search support
+
+ The `date:` prefix can now be used in queries to restrict the results
+ to only messages within a particular time range (based on the Date:
+ header) with a range syntax of `date:<since>..<until>`. Notmuch
+ supports a wide variety of expressions in `<since>` and
+ `<until>`. Please refer to the `notmuch-search-terms(7)` manual page
+ for details.
