Release: AWS SDK for JavaScript v2.3.0

Updates AWS.ELB with CORS support. Elastic Load Balancing is now a default service in the browser distribution of the SDK.

Updates AWS.ECS with CORS support. Amazon EC2 Container Service is now a default service in the browser distribution of the SDK.

Updates the AWS.Request object with a promise() method. This method will return a promise that is fulfilled with a response data object, and rejected with an error object.

Example:

var putObjectPromise = s3.putObject({Bucket: 'bucket', Key: 'key'}).promise();
putObjectPromise.then(function(data) {
  console.log('PutObject succeeded');
}).catch(function(err) {
  console.log(err);
});

Note: This currently only works for operations that return an instance of AWS.Request.
