    const builder = new Alexa.templateBuilders.BodyTemplate7Builder();
    const template = builder.setBackgroundImage(Alexa.utils.ImageUtils.makeImage('http://url/to/my/backgroundimg.png'))
                                        .setBackButtonBehavior('HIDDEN')
                                        .setImage(Alexa.utils.ImageUtils.makeImage('http://url/to/my/img.png'))
                                        .build();
    this.response.speak('Rendering a template!')
                .renderTemplate(template);
    this.emit(':responseReady');

Support for Progresive Response API

This release adds SDK support for progressive response API.

The DirectiveService provides the following function to access the Progressive Response API:

enqueue(directive, apiEndpoint, token);

An example to send directive to the service API is as follows:

function callDirectiveService(event) {
    // Call Alexa Directive Service.
    const ds = new Alexa.services.DirectiveService();
    const requestId = event.request.requestId;
    const endpoint = event.context.System.apiEndpoint;
    const token = event.context.System.apiAccessToken;
    const directive = new Alexa.directives.VoicePlayerSpeakDirective(requestId, "This is a message");
    ds.enqueue(directive, endpoint, token)
    .catch((err) => {
        console.log(err.message);
    });
}

Remove unused state from HandlerContext

This release removes an unused state property from HandlerContext.
this.state in handlers is never assigned value nor used in the state management logic. Developers should use this.handler.state instead to manage state value.

List Management API Helper

This release includes a new helper class: ListManagementService that helps developers to better utilize the Alexa List API.

The ListManagmentService provides the following functions to access Alexa List API:

getListsMetadata(token)
createList(listObkect, token)
getList(listId, itemStatus, token)
updateList(listId, listObject, token)
deleteList(listId, token)
createListItem(listId, listItemObject, token)
getListItem(listId, itemId, token)
updateListItem(listId, itemId, listItemObject, token)
deleteListItem(listId, itemId, token)

An example to create a named list is as follows:

const Alexa = require('alexa-sdk');
'CreateListIntent': function () {
        if (this.event.context.System.user.permissions) {
            let token = this.event.context.System.user.permissions.consentToken;

            let lms = new Alexa.services.ListManagementService();
            let listObject = {
                name : 'My Test List',
                state : 'active',
                version : 1
            };
            lms.createList(listObject, token)
                .then((data) => {
                    this.response.speak('List successfully created!');
                     this.emit(':responseReady');
                })
                .catch((error) => {
                    console.log(error.message);
                    this.response.speak('Unable to create List!');
                    this.emit(':responseReady');
                });
        } else {
           this.response.speak('Please grant skill permissions to access Alexa List API.');
           this.emit(':responseReady');
        }
}
