This beta version has breaking changes, a migration guide is available at https://www.weaviate.io/developers/weaviate/client-libraries/python#migration-guides:
- Refactor ``weaviate.classes`` structure
- Rename various classes and methods:
- In all vectorizer configuration methods: ``vectorize_class_name`` => ``vectorize_collection_name``
- ``object.metadata.creation_time_unix`` => ``object.metadata.creation_time`` which is now a datetime
- ``object.metadata.last_update_time_unix`` => ``object.metadata.last_update_time`` which is now a datetime
- ``MetadataQuery(creation_time_unix=.., last_update_time_unix= ..)`` => ``MetadataQuery(creation_time=.., last_update_time=..)``
- ``FromReference`` => ``QueryReference`` when querying references
- Splits out references from properties when creating, changing and querying collections
- UUID and UUID_ARRAY properties are now returned as typed UUID objects
- DATE and DATE_ARRAY properties are now returned as typed datetime objects
- ``vector_index_type``has been remove from ``collection.create()`` and is now determined automatically
- ``Configure.vector_index()`` has been moved to ``Configure.VectorIndex.hnsw()``
- PQ can now be configured using Configure.VectorIndex.hnsw(quantitizer=Configure.VectorIndex.Quantitizer.pq(..options..))
- ``object.metadata.vector`` was moved to ``object.vector`` and can be requested by using ``include_vector=True/False`` when querying
- ``object.metadata.uuid`` was moved to ``object.uuid`` and is always available
- Order of arguments in .data.update() and .replace() changed to accommodate not providing properties when updating.
- In .data.reference_add, .reference_delete and .reference_replace the ``ref`` keyword was renamed to ``to``
- In collections.create() and .get() the keyword to provide generics was renamed from ``data_model`` to ``data_model_properties``
New functionality includes:
- Adds backup functionality to v4 client (``client.backup``) and directly to the collection (``collection.backup``)
- Adds support for FLAT vector index
- Adds binary quantization for FLAT vector index
- Adds ``text2vec_jinaai`` static method to ``Configure.Vectorizer``
- Adds ``anyscale`` static method to ``Configure.Generative``
- Adds collection.batch for uploading to a single collection in batches
- Adds methods for creating a collection from dict and exporting a collection config as dict
- Adds support for geo-coordinates
- Adds metadata filtering with ``FilterMetadata``
- Adds ``client.graphql_raw_query`` to use Weaviate features that are not directly supported.
