Version 3.0.0-rc0 (2021-08-03)

Added

Annotation types
- A set of python objects for working with labelbox data
- Creates a standard interface for both exports and imports
- See example notebooks on how to use under examples/annotation_types
- Note that these types are not yet supported for tiled imagery
MEA Support
- Beta MEA users can now just use the latest SDK release
Metadata support
- New metadata features are now fully supported by the SDK
Easier export
- project.export_labels() accepts a boolean indicating whether or not to download the result
- Create annotation objects directly from exports with project.label_generator() or project.video_label_generator()
- project.video_label_generator() asynchronously fetches video annotations
Retry logic on data uploads
- Bulk creation of data rows will be more reliable
Datasets
- Determine the number of data rows just by calling dataset.row_count.
- Updated threading logic in create_data_rows() to make it compatible with aws lambdas
Ontology
- OntologyBuilder, Classification, Option, and Tool can now be imported from labelbox instead of labelbox.schema.ontology

Deprecated:
- project.reviews()
- project.create_prediction()
- project.create_prediction_model()
- project.create_label()
- Project.predictions()
- Project.active_prediction_model
- data_row.predictions
- PredictionModel
- Prediction
Replaced:
- data_row.metadata() use data_row.attachments() instead
- data_row.create_metadata() use data_row.create_attachments() instead
- AssetMetadata use AssetAttachment instead

Support derived classes of ontology objects when using from_dict
Notebooks:
- Video export bug where the code would fail if the exported projects had tools other than bounding boxes
- MAL demos were broken due to an image download failing.

Data processing dependencies are not installed by default to for users that only want client functionality.
To install all dependencies required for the data modules (annotation types and mea metric calculation) use pip install labelbox[data]. For a specific version (such as the rc release) use pip install "labelbox[data]==3.0.0rc0"
