# 1.15.x -> 1.16.0

## Breaking Changes

### Framework affected: `Portal`

#### Changes to DeviceService API

* There were three ways to activate the device before release 1.16.0.
  1. `ACTIVATE`
  2. `ACTIVATE_LIMIT_ONE`
  3. `ACTIVATE_ONLY_IF_NO_ACTIVE_DEVICE`
* Currently 1.16.0 onwards there is only one way to activate the device.

#### Concrete Example

To activate the device using the versions **below** 1.16.0, one can use following snippet

```swift
let service = DeviceService(identity: identity)
service.activate(mode: .activate, then: { result in
    switch result {
    case: .success(_)
        // activation successful
    case: .failure(_)
        // failure error
    }
})
```

#### Concrete Example

To activate the device using the SDK versions 1.16.0 **and onwards**, one can use following snippet

```swift
let service = DeviceService(identity: identity)
service.activate(then: { result in
    switch result {
    case: .success(_)
        // activation successful
    case: .failure(_)
        // failure error
    }
})
```
