# Helm Chart v2.0

> FlowFuse Helm Chart Update: v2 introduces streamlined upgrades and enhanced capabilities for managing resource constraints and Pod Security Context.

The v2.0 release of the FlowFuse Helm Chart includes a breaking change for deployments making use of the `forge.localPostgresql` setting when upgrading. This is where the helm chart installs a dedicated PostgreSQL database instance.

With v2.0 we have updated the version of the Bitnami PostgreSQL Helm sub-chart we bundle and the upgrade process will require some manual intervention to ensure things work correctly. A fresh install should not require any extra steps.

The steps are documented on the [Upgrade instructions](/docs/install/kubernetes/#upgrade) page, please read them carefully before upgrading

Also included in this release is the ability to set resource constraints and Pod Security Context on the FlowFuse application, File-Server Application and MQTT broker containers if required. Details of how to set those can be found in the Helm Chart [README.md](https://github.com/FlowFuse/helm/tree/main/helm/flowforge#readme)
