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](https://kuzudb.com/blog/kuzu-0.0.2-release.html) 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](https://kuzudb.com/blog/what-every-gdbms-should-do-and-vision.html) and [how we implemented factorization inside Kùzu](https://kuzudb.com/blog/factorization.html).
Enjoy your reading and don't forget to `pip install kuzu`!
