## New kong-plugins Helm Chart available

This change is **mandatory for clients that use the SDK / Public API**. A new Unique Helm Chart for `kong-plugins` has been released, addressing a critical bug related to the use of company-scoped API keys. The bug caused errors when calling any public endpoint with a company-scoped API key. Please ensure this update is applied promptly to avoid disruptions.

Check the changes on Artifact Hub: [Artifact Hub](https://artifacthub.io/packages/helm/unique/kong-plugins)

## Steps

1. Upgrade the `kong-plugins` to `1.2.1`.

2. Deploy the changes.

3. Verify the fix by calling SDK/public API endpoints using the API key and observing a successful response.
