# Overview

This topic describes features of SMP (Self-Managed Platform).

Feature availability on HCE SaaS and SMP are on par, with minor timeline changes in the SMP feature releases.

The table below outlines the roadmap for the Harness Self-Managed Enterprise Edition of Chaos Engineering:

### Prerequisites <a href="#prerequisites" id="prerequisites"></a>

This section describes the prerequisites to fulfill before using Enterprise ChaosHub.

The table below describes the SMP version and its equivalent chaos manager image required to connect to Enterprise ChaosHub. Use the equivalent of the image mentioned here from your image registry.

| Version | Chaos Manager Image                               |
| ------- | ------------------------------------------------- |
| 0.26.x  | docker.io/harness/smp-chaos-manager-signed:1.54.1 |
| 0.25.x  | docker.io/harness/smp-chaos-manager-signed:1.53.2 |
| 0.24.x  | docker.io/harness/smp-chaos-manager-signed:1.49.3 |
| 0.23.x  | docker.io/harness/smp-chaos-manager-signed:1.47.7 |

Update the chaos-manager image tag in the helm-override:

```yaml
chaos:
  chaos-manager:
    image:
      tag: "1.47.7" #Update the tag of chaos-manager image here
```
