## Deployment notes

### Standard deployment

This maintenance release follows standard FlowX.AI deployment procedures with no special considerations:

1. Update container images to 5.1.6 versions listed in the table
2. Deploy services using your standard deployment process
3. Verify deployment via **FlowX Designer > Platform Status**

### Configuration changes

<Info>
  This release introduces optional environment variables for the process engine retry mechanism. These are not required — defaults work for most deployments.
</Info>

#### Process engine — retry configuration (optional)

The following optional environment variables configure the exponential backoff with Equal Jitter strategy used for optimistic locking retries:

| Environment Variable        | Description                                                | Default Value | Component      |
| --------------------------- | ---------------------------------------------------------- | ------------- | -------------- |
| `FLOWX_RETRY_MAX_RETRIES`   | Maximum retry attempts (total = max + 1 including initial) | `9`           | process-engine |
| `FLOWX_RETRY_BASE_DELAY_MS` | Initial backoff delay in milliseconds                      | `10`          | process-engine |
| `FLOWX_RETRY_MAX_DELAY_MS`  | Maximum backoff delay cap in milliseconds                  | `200`         | process-engine |

<Check>
  No required configuration changes
  No database migrations
  No breaking changes
  Compatible with existing 5.1.5 processes and configurations
