v0.8.3

Added

• New parameters of pw.UDF class and pw.udf decorator: return_type, deterministic, propagate_none, executor, cache_strategy.
• The LLM Xpack now provides integrations with LlamaIndex and LangChain for running the Pathway VectorStore server.

Changed

• Subclassing UDFSync and UDFAsync is deprecated. UDF should be subclassed to create a new UDF.
• Passing keyword arguments to pw.apply, pw.apply_with_type, pw.apply_async is deprecated. In the future, they'll be used for configuration, not passing data to the function.

Fixed

• Fixed a minor bug with Table.groupby() method which sometimes prevented of accessing certain columns in the following reduce().
• Fixed warnings from using OpenAI Async embedding model in the VectorStore in Colab.
