Using the S130 alpha SD

Question

I'm trying to test the throughput improvement of the S130 alpha softdevice vs S130 V1. 
 I notice a couple of changes in the API that I'm not sure how to handle: 
 First, ble_enable_params_t has changed and so has the number of arguments for sd_ble_enable. My old code looks like this: 
 ble_enable_params.gatts_enable_params.service_changed = false;
ble_enable_params.gap_enable_params.role = BLE_GAP_ROLE_CENTRAL;
err_code = sd_ble_enable(&ble_enable_params);
 
 There is no longer a "role" field and sd_ble_enable requires more arguments. Is there an example of how to call this? 
 Also, is there an existing define for the alpha release headers so I can protect the old code with an #ifndef S130_ALPHA or some such macro? 
 At this point I should also ask what other changes need to be made to the project in order to use the S130 alpha? All I've done so far is create a new folder for the new header files and changed the ble path in the project to point to that folder. 
 For example, is there anything I need to do to tell the SD to accept 3 packets per connection interval or is that automatic?

For an example of how to call sd_ble_enable, take a look at ble_stack_init() in the SDK examples. For your convenience, here it is: 
 #if defined(S110) || defined(S130) || defined(S132)
 // Enable BLE stack.
 ble_enable_params_t ble_enable_params;
 memset(&ble_enable_params, 0, sizeof(ble_enable_params));
#if (defined(S130) || defined(S132))
 ble_enable_params.gatts_enable_params.attr_tab_size = BLE_GATTS_ATTR_TAB_SIZE_DEFAULT;
#endif
 ble_enable_params.gatts_enable_params.service_changed = IS_SRVC_CHANGED_CHARACT_PRESENT;
 err_code = sd_ble_enable(&ble_enable_params);
 APP_ERROR_CHECK(err_code);
#endif
 
 The macro S130 is defined in the preprocessor symbols, so you can add your old code inside an #ifdef S130_ALPHA and change the macro to S130_ALPHA to use old code. 
 I don't have a complete overview of the changes, but they should be in the release notes located in the SoftDevice folder (zip file downloaded). 
 As far as I know, you don't need to tell the SoftDevice to accept 3 packets per connection interval, this is automatic.
