**Features and Improvements**

- Added support for JSON Patch test operations, via the ``expect`` parameter.
- Added support for moving values via --append-list
(Now, rather than ignoring any requests where the value is already present,
--append-list will move the value to the end of the list).
- Switched to importlib-metadata to drop deprecated pkg_resources.

**Bugfixes**

- Fixed automatic size hint on uploads.
- Fixed bug where auth wasn't being sent for searches with user_aggs params.

of hits for a query.

some cases

**Features and Improvements**

- Added support for inserting metadata into an existing multi-value metadata
field. It differs from ``ia metadata <id> --modify collection[0]:foo`` in
that it does not clobber. For example,
``ia metadata <id> --insert collection[0]:foo`` will insert ``foo`` as the
first collection, it will not clobber.

**Bugfixes**

- Fixed bug in search where timeouts would always be returned on queries
submitted to the files index where more than 10,000 results would be
returned.
