This new feature allows you to join your streaming instances to your AD, so you can use your existing AD user management tools. 
* feature: EC2: Spot Fleet tagging capability allows customers to automatically tag instances launched by Spot Fleet. You can use this feature to label or distinguish instances created by distinct Spot Fleets. Tagging your EC2 instances also enables you to see instance cost allocation by tag in your AWS bill.

* feature: Lambda: Lambda@Edge lets you run code closer to your end users without provisioning or managing servers. With Lambda@Edge, your code runs in AWS edge locations, allowing you to respond to your end users at the lowest latency. Your code is triggered by Amazon CloudFront events, such as requests to and from origin servers and viewers, and it is ready to execute at every AWS edge location whenever a request for content is received. You just upload your Node.js code to AWS Lambda and Lambda takes care of everything required to run and scale your code with high availability. You only pay for the compute time you consume - there is no charge when your code is not running.

You can use the new dashboard APIs or CloudFormation templates to dynamically build and maintain dashboards to monitor your infrastructure and applications. There are four new dashboard APIs - PutDashboard, GetDashboard, DeleteDashboards, and ListDashboards APIs. PutDashboard is used to create a new dashboard or modify an existing one whereas GetDashboard is the API to get the details of a specific dashboard. ListDashboards and DeleteDashboards are used to get the names or delete multiple dashboards respectively. Getting started with dashboard APIs is similar to any other AWS APIs. The APIs can be accessed through AWS SDK or through CLI tools.

* feature: CloudWatchEvents: CloudWatch Events now allows different AWS accounts to share events with each other through a new resource called event bus. Event buses accept events from AWS services, other AWS accounts and PutEvents API calls. Currently all AWS accounts have one default event bus. To send events to another account, customers simply write rules to match the events of interest and attach an event bus in the receiving account as the target to the rule. The PutTargets API has been updated to allow adding cross account event buses as targets. In addition, we have released two new APIs - PutPermission and RemovePermission - that enables customers to add/remove permissions to their default event bus.
* feature: GameLift: Allow developers to download GameLift fleet creation logs to assist with debugging.

## 2.78.0
* feature: ServiceCatalog: Proper tagging of resources is critical to post-launch operations such as billing, cost allocation, and resource management. By using Service Catalog's TagOption Library, administrators can define a library of re-usable TagOptions that conform to company standards, and associate these with Service Catalog portfolios and products. Learn how to move your current tags to the new library, create new TagOptions, and view and associate your library items with portfolios and products. Understand how to ensure that the right tags are created on products launched through Service Catalog and how to provide users with defined selectable tags.

## 2.77.0
* feature: Lambda: The Lambda Invoke API will now throw new exception InvalidRuntimeException (status code 502) for invokes with deprecated runtimes.

## 2.76.0
* feature: CodePipeline: A new API, ListPipelineExecutions, enables you to retrieve summary information about the most recent executions in a pipeline, including pipeline execution ID, status, start time, and last updated time.

* feature: ELB: Add retry error state to InstanceInService waiter for ElasticLoadBalancer
* feature: Lightsail: This release adds a new nextPageToken property to the result of the GetOperationsForResource API. Developers can now get the next set of items in a list by making subsequent calls to GetOperationsForResource API with the token from the previous call. This release also deprecates the nextPageCount property, which previously returned null (use the nextPageToken property instead). This release also deprecates the customImageName property on the CreateInstancesRequest class, which was previously ignored by the API.
* feature: Route53: This release reintroduces the HealthCheckInUse exception.

## 2.75.0
* feature: DAX: Amazon DynamoDB Accelerator (DAX) is a fully managed, highly available, in-memory cache for DynamoDB that delivers up to a 10x performance improvement - from milliseconds to microseconds - even at millions of requests per second. DAX does all the heavy lifting required to add in-memory acceleration to your DynamoDB tables, without requiring developers to manage cache invalidation, data population, or cluster management.
* feature: Route53: Amazon Route 53 now supports multivalue answers in response to DNS queries, which lets you route traffic approximately randomly to multiple resources, such as web servers. Create one multivalue answer record for each resource and, optionally, associate an Amazon Route 53 health check with each record, and Amazon Route 53 responds to DNS queries with up to eight healthy records.
* feature: S3: Allows forward slashes in Bucket names when using SigV4 to create or retrieve objects. This is to maintain compatibility with behavior when using SigV2. In new code, Buckets should not contain forward slashes. Instead, directories should be part of an object's key.

The first rule is for configuring missing data treatment. Customers have the options to treat missing data as alarm threshold breached, alarm threshold not breached, maintain alarm state and the current default treatment. The second rule is for alarms based on percentiles metrics that can trigger unnecassarily if the percentile is calculated from a small number of samples. The new rule can treat percentiles with low sample counts as same as missing data. If the first rule is enabled, the same treatment will be applied when an alarm encounters a percentile with low sample counts.

## 2.37.0

Once a file share is created, any changes made externally to the S3 bucket will not be reflected by the gateway. Using the cache refresh feature in this update, the customer can trigger an on-demand scan of the keys in their S3 bucket and refresh the file namespace cached on the gateway. It takes as an input the fileShare ARN and refreshes the cache for only that file share. Additionally there is new functionality on file gateway that allows you configure what squash options they would like on their file share, this allows a customer to configure their gateway to not squash root permissions. This can be done by setting options in NfsOptions for CreateNfsFileShare and UpdateNfsFileShare APIs.

* feature: RDS: You can now use the AWS Management Console to easily move your DB instance to a different VPC, or to a different subnet group in the same VPC.

This option can be considerably faster than migrating data using mysqldump.

## 2.4.12
* bugfix: Request: Adds a content-length check for the stream returned from `createReadStream()`, and the stream will emit an error when the bytes received are fewer than specified by the response content-length header.
* bugfix: S3: Reverts behavior introduced in version `2.4.0` of the SDK to default the `signatureVersion` of S3 clients to `v4`. S3 clients instantiated without a user-defined `signatureVersion` will now default to `v2` unless the region only supports `v4` signing. This change is being made due to issues sending non-ascii characters in headers when using `v4` signing.
