Release 8.x.x

IMPORTANT - In HeavyDB Release 8.x.x, the system catalog is automatically migrated to support the new Column Level Security feature. This migration is necessary regardless if you intend to use this feature or not. Once the system catalog has been migrated in this manner, it is not backwards-compatible with earlier versions of HeavyDB. If you revert to an earlier version in this state, the system will be in an unstable state and manual intervention will be required. We recommend backing up your data before you upgrade HEAVY.AI.

8.x.x introduces a new licensing version that feature two new types of licenses: Node Locked Licenses and Floating Licenses. Enterprise customers that are upgrading to the 8.x release of HEAVY.AI are required to reach out to the HEAVY.AI Customer Success team for a new license before attempting to upgrade.

HeavyIQ requires no external API calls and guarantees data privacy by virtue of being a fully offline model.
The primary interface point for the new HeavyIQ conversational analytics capabilities are via the new SQL editor (see above), but it can also be utilized via API if desired.
