• TimescaleDB: >= 2.6.1 single-node (multi-node is not supported in this release)
• Promscale Database Extension: >=0.5.x.

Upgrade notes

• Before starting the upgrade please make sure that you have deployed version 0.5.x of the Promscale extension. You will also need TimescaleDB extension version 2.6.1 or above available.
