v1.0.0-beta.1

Added

• Added type annotations across the library (#309)
• Added assets to collections (#309)
• item_assets extension (#309)
• datacube extension (#309)
• Added specific errors: ExtensionAlreadyExistsError, ExtensionTypeError, and RequiredPropertyMissing; moved custom exceptions to pystac.errors (#309)

Fixed

• Validation checks in a few tests (#346)

Changed

• API change: The extension API changed significantly. See (#309) for more details.
• API change: Refactored the global STAC_IO object to an instance-specific StacIO implementation. STAC_IO is deprecated and will be removed next release. (#309)
• Asset.get_absolute_href returns None if no absolute href can be inferred (previously the relative href that was passed in was returned) (#309)

Removed

• Removed properties from Collections (#309)
• Removed LinkMixin, and implemented those methods on STACObject directly. STACObject was the only class using LinkMixin and this should not effect users (#309
• Removed single-file-stac extension; this extension is being removed in favor of ItemCollection usage (#309

Version 0.5.6

Added

• HIERARCHICAL_LINKS array constant of all the types of hierarchical links (self is not included) (#290)

Fixed

• Fixed error when accessing the statistics attribute of the pointcloud extension when no statistics were defined (#282)
• Fixed exception being thrown when calling set_self_href on items with assets that have relative hrefs (#291)

Changed

• Link behavior - link URLs can be either relative or absolute. Hierarchical (e.g., parent, child) links are made relative or absolute based on the value of the root catalog's catalog_type field (#290)
• Internal self hrefs are set automatically when adding Items or Children to an existing catalog. This removes the need to call normalize_hrefs or manual setting of the hrefs for newly added STAC objects (#294)
• Catalog.generate_subcatalogs is an order of magnitude faster (#295)

Removed

• Removed LinkType class and the link_type field from links (#290)

Version 0.5.5

Added

• Added support for STAC file extension (#270)

Fixed

• Fix handling of optional properties when using apply on view extension (#259)
• Fixed issue with setting None into projection extension fields that are not required breaking validation (#269)
• Remove unnecessary deepcopy calls in to_dict methods to avoid costly overhead (#273)

Changed

• Subclass relevant classes from enum.Enum. This allows iterating over the class' contents. The __str__ method is overwritten so this should not break backwards compatibility. (#261)
• Extract method to correctly handle setting properties in Item/Asset for ItemExtensions (#272)
