Changed
^^^^^^^

are now ignored. See

plugin can be found in

- Added /config route; see
https://github.com/jic-dtool/dservercore/pull/6

UUIDs of interest to a query submitted to the /dataset/search route; see
https://github.com/jic-dtool/dservercore/pull/8
- Added dtool_lookup_server.utils.preprocess_query_base_uris helper function; see
https://github.com/jic-dtool/dservercore/pull/7 and
https://github.com/jic-dtool/dservercore/issues/10

as floats rather than as strings; see

https://github.com/jic-dtool/dservercore/pull/5
