v0.0.11

We release Kùzu 0.0.11, another minor release. The main new feature of this release is read-only access mode for the database on Linux (#2089, #2229 and #2233).

V0.0.3

We are happy to release Kùzu 0.0.3. This release comes with the following new main features and improvements:

• Kùzu as a Pytorch Geometric (PyG) Remote Backend: You can now train PyG GNNs and other models directly using graphs (and node features) stored on Kùzu. See this Colab notebook for a demonstrative example.
• Data ingestion from multiple files and numpy files.
• Query optimizer improvements.
• New buffer manager.
• INT32, INT16, FLOAT, and FIXED LIST data types (the latter is particularly suitable to store node features in graph ML applications)
• Query timeout mechanism and interrupting queries from CLI.

See our blog post for more details. Enjoy your reading and don't forget to pip install kuzu!
