v0.8.0

We're kicking off the year 2025 with the exciting release of Kùzu 0.8.0, which brings two new features:

1. Kùzu-WASM for in-browser graph analytics. You can now run your graph database while keeping all data and compute within your browser session!
2. fts extension for full-text search. You can now run keyword-based search queries using BM25 in Kùzu.

In addition to these new features, we’ve streamlined the developer workflow during relationship table creation by unifying CREATE REL TABLE GROUP into a single, flexible CREATE REL TABLE syntax.

Finally, we’ve significantly improved our execution of aggregation queries via a new parallel hash aggregation mechanism.

Please check our release post for more details. Hope you enjoy this release!
