V0.0.7

Welcome to Kùzu 0.0.7! In this release, we've introduced following main improvements and features:

• Supported CREATE MACRO and both scalar and vectorized UDFs in C++ APIs.
• Supported MERGE clause, which is the Cypher version of SQL's UPSERT statement.
• Supported multi-label DELETE/SET.
• Supported exporting query result to csv files through the COPY TO clause. Also, exporting query result to arrow arrays is now available in C/C++ and Rust APIs.
• Introduced new data types: MAP and UNION.
• Improved RETURN clause with two minor features: 1) RETURN after update; 2) RETURN with .*.
• Improved sub query execution with unnesting optimization.
• Introduced NodeGroup based storage layout for node tables.

As usual, we have more details in our blog post. Enjoy your reading!
