Changes in version 1.2.0                        

    o   Switch to rappdirs to choose the cache directory. This allows
	re-use of the cache with the equivalent Python client.

    o   Improve handling of unexpected errors with non-JSON bodies.

    o   Added the unlockProject() utility for administrators.

    o   Renamed defineTextQuery() to gsc() (for “gypsum search clause”)
	and generalized it to other fields in the SQLite file.
	Specifically, it now can filter based on the path to the
	metadata document, the project, asset or version names, the
	identity of the uploader and the timestamp of the upload.

    o   Renamed searchMetadataText() to searchMetadata(), to reflect
	the more general nature of the search with the new gsc()
	function. The old name is now soft-deprecated.

    o   Renamed searchMetadataTextFilter() to searchMetadataFilter(),
	to reflect the more general nature of the search. The old name
	is now soft-deprecated. Also added arguments to support custom
	names/aliases for the project, asset, version and path columns.

                        Changes in version 1.0.1                        

    o   Read-only operations now use the relevant REST endpoints rather
	than directly contacting the S3 API. This avoids a dependency
	on paws.storage and fixes some strange issues with the request
	signing.

                        Changes in version 1.0.0                        

    o   New gypsum package to interact with the REST API of the same
	name.
