 description: Kong is a scalable, open source API layer (aka API gateway or API middleware) that runs in front of any RESTful API. Extra functionalities beyond the core platform are extended through plugins. Kong is built on top of reliable technologies like NGINX and provides an easy-to-use RESTful API to operate and configure the system.

+### To 3.0.0
+
+[On November 13, 2020, Helm v2 support was formally finished](https://github.com/helm/charts#status-of-the-project), this major version is the result of the required changes applied to the Helm Chart to be able to incorporate the different features added in Helm v3 and to be consistent with the Helm project itself regarding the Helm v2 EOL.
+
+**What changes were introduced in this major version?**
+
+- Previous versions of this Helm Chart use `apiVersion: v1` (installable by both Helm 2 and 3), this Helm Chart was updated to `apiVersion: v2` (installable by Helm 3 only). [Here](https://helm.sh/docs/topics/charts/#the-apiversion-field) you can find more information about the `apiVersion` field.
+- Move dependency information from the *requirements.yaml* to the *Chart.yaml*
+- After running `helm dependency update`, a *Chart.lock* file is generated containing the same structure used in the previous *requirements.lock*
+- The different fields present in the *Chart.yaml* file has been ordered alphabetically in a homogeneous way for all the Bitnami Helm Charts
+- This chart depends on the **PostgreSQL 10** instead of **PostgreSQL 9**. Apart from the same changes that are described in this section, there are also other major changes due to the master/slave nomenclature was replaced by primary/readReplica. [Here](https://github.com/bitnami/charts/pull/4385) you can find more information about the changes introduced.
+
+**Considerations when upgrading to this version**
+
+- If you want to upgrade to this version from a previous one installed with Helm v3, you shouldn't face any issues
+- If you want to upgrade to this version using Helm v2, this scenario is not supported as this version doesn't support Helm v2 anymore
+- If you installed the previous version with Helm v2 and wants to upgrade to this version with Helm v3, please refer to the [official Helm documentation](https://helm.sh/docs/topics/v2_v3_migration/#migration-use-cases) about migrating from Helm v2 to v3
