Version 0.0.2 Release

This release introduces several major changes:

• Support data import from parquet and arrow IPC files.
• Support data export to PyG, NetworkX, Pandas, Arrow.
• Support UTF-8 strings and regular expression matching for strings.
• Support ALTER TABLE DDL and SET/DROP for node/rel properties.
• Support multi/un -labelled queries.
• New expressions/functions. (CASE expression, string regular expression match ~=, etc.)

We've written a blog post to explain our major new features in this release.
In case you missed it, Semih also had written two nice blog posts to explain the goals and vision of Kùzu and how we implemented factorization inside Kùzu.
Enjoy your reading and don't forget to pip install kuzu!
