This breaking release brings caltechdata_api in line with the 2.0 release of the CaltechDATA. The primary change is that the default metadata schema will be the InvenioRDM schema https://inveniordm.docs.cern.ch/reference/metadata/. This is the native schema for CaltechDATA, and makes it easier to round-trip data. You can continue sending metadata in DataCite format is you use the schema="43" parameter.
It also has integrated support for file linking to files in an Open Storage Network bucket.
Full Changelog: v1.11.0...v2.0.0
