v0.6.0 2026-05-13

🎨 NeMo Data Designer v0.6.0

This release comes with two major updates:

• ⚡ Async by default: The async execution engine is now the default path in Data Designer. Pipelines schedule work at the cell level, overlapping independent columns and adapting model concurrency per provider/model.

• 🔌 Plugins are stable: Plugins have moved out of experimental mode. Seed readers, column generators, and processors can now live in normal Python packages with typed configs and entry-point discovery.
