v1.0.0-rc.1

Added

• License file included in distribution (#409)
• Links to Issues, Discussions, and documentation sites (#409)
• Python minimum version set to >=3.6 (#409)
• Code of Conduct (#399)
• ItemCollection class for working with GeoJSON FeatureCollections containing only
  STAC Items (#430)
• Support for Python 3.9 (#420)
• Migration for pre-1.0.0-rc.1 Stats Objects (renamed to Range Objects in 1.0.0-rc.3) (#447)
• Attempting to extend a STACObject that does not contain the extension's schema URI in
  stac_extensions raises new ExtensionNotImplementedError (#450)
• STACObject.from_dict now takes a preserve_dict parameter, which if False will avoid a call to deepcopy on the passed in dict and can result in performance gains (defaults to True. Reading from a file will use preserve_dict=False resulting in better performance. (#454)

Changed

• Package author to stac-utils, email to [email protected], url to this repo (#409)
• StacIO.read_json passes arbitrary positional and keyword arguments to
  StacIO.read_text (#433)
• FileExtension updated to work with File Info Extension v2.0.0 (#442)
• FileExtension only operates on pystac.Asset instances (#442)
• *Extension.ext methods now have an optional add_if_missing argument, which will
  add the extension schema URI to the object's stac_extensions list if it is not
  present (#450)
• from_file and from_dict methods on STACObject sub-classes always return instance
  of calling class (#451)

Fixed

• EOExtension.get_bands returns None for asset without EO bands (#406)
• identify_stac_object_type returns None and identify_stac_object raises STACTypeError for non-STAC objects
  (#402)
• ExtensionManagementMixin.add_to is now idempotent (only adds schema URI to
  stac_extensions once per Item regardless of the number of calls) (#419)
• Version check for when extensions changed from short links to schema URIs
  (#455)
• Schema URI base for STAC 1.0.0-beta.1 (#455)
