### Service Client Updates
* `service/accessanalyzer`: Updates service API and documentation

### SDK Features
* SDK generated errors are fixed to use pointer receivers preventing confusion, and potential impossible type assertions. The SDK will only return API generated API error types as pointers. This fix ensures Go's type system will catch invalid error type assertions.

### SDK Enhancements
* Update SDK's `go-jmespath` dependency to latest tagged version `0.3.0` ([#3205](https://github.com/aws/aws-sdk-go/pull/3205))

### SDK Bugs
* Fix generated SDK errors to use pointer receivers
  * Fixes the generated SDK API errors to use pointer function receivers instead of value. This fixes potential confusion writing code and not casting to the correct type. The SDK will always return the API error as a pointer, not value.
  * Code that did type assertions from the operation's returned error to the value type would never be satisfied. Leading to errors being missed. Changing the function receiver to a pointer prevents this error. Highlighting it in code bases.

### SDK Enhancements
* `aws/signer/v4`: Always sign a request with the current time. ([#2336](https://github.com/aws/aws-sdk-go/pull/2336))
  * Updates the SDK's v4 request signer to always sign requests with the current time. For the first request attempt, the request's creation time was used in the request's signature. In edge cases this allowed the signature to expire before the request was sent if there was significant delay between creating the request and sending it, (e.g. rate limiting).
* `aws/endpoints`: Deprecate endpoint service ID generation. ([#2338](https://github.com/aws/aws-sdk-go/pull/2338))
  * Deprecates the service ID generation. The list of service IDs do not directly 1:1 relate to a AWS service. The set of ServiceIDs is confusing, and inaccurate. Instead users should use the EndpointID value defined in each service client's package

* Fix SDK's vet usage to use go vet with build tags ([#2300](https://github.com/aws/aws-sdk-go/pull/2300))
  * Updates the SDK's usage of vet to use go vet instead of go tool vet. This allows the SDK to pass build tags and packages instead of just folder paths to the tool.

### Service Client Updates
* `service/snowball`: Updates service API
  * Snowball job states allow customers to track the status of the Snowball job. We are launching a new Snowball job state "WithSortingFacility"!

  * Read Replicas for Amazon RDS for MySQL, MariaDB, and PostgreSQL now support Multi-AZ deployments.Amazon RDS Read Replicas enable you to create one or more read-only copies of your database instance within the same AWS Region or in a different AWS Region. Updates made to the source database are asynchronously copied to the Read Replicas. In addition to providing scalability for read-heavy workloads, you can choose to promote a Read Replica to become standalone a DB instance when needed.Amazon RDS Multi-AZ Deployments provide enhanced availability for database instances within a single AWS Region. With Multi-AZ, your data is synchronously replicated to a standby in a different Availability Zone (AZ). In case of an infrastructure failure, Amazon RDS performs an automatic failover to the standby, minimizing disruption to your applications.You can now combine Read Replicas with Multi-AZ as part of a disaster recovery strategy for your production databases. A well-designed and tested plan is critical for maintaining business continuity after a disaster. Since Read Replicas can also be created in different regions than the source database, your Read Replica can be promoted to become the new production database in case of a regional disruption.You can also combine Read Replicas with Multi-AZ for your database engine upgrade process. You can create a Read Replica of your production database instance and upgrade it to a new database engine version. When the upgrade is complete, you can stop applications, promote the Read Replica to a standalone database instance and switch over your applications. Since the database instance is already a Multi-AZ deployment, no additional steps are needed.For more information, see the Amazon RDS User Guide.

  * Amazon Web Services announced the immediate availability of two additional alarm configuration rules for Amazon CloudWatch Alarms. 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 unnecessarily 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.

  * File gateway mode in AWS Storage gateway provides access to objects in S3 as files on a Network File System (NFS) mount point. 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.

### Service Client Updates
* `service/batch`: Updates service API, documentation, and paginators

This is the number of non successful executions before a job is considered FAILED. In addition, the JobDetail object now has an attempts field and shows all execution attempts.
* `service/ec2`: Updates service API and documentation
	* Customers can now tag their Amazon EC2 Instances and Amazon EBS Volumes at
	the time of their creation. You can do this from the EC2 Instance launch
	wizard or through the RunInstances or CreateVolume APIs. By tagging
	resources at the time of creation, you can eliminate the need to run custom
	tagging scripts after resource creation. In addition, you can now set
	resource-level permissions on the CreateVolume, CreateTags, DeleteTags, and
	the RunInstances APIs. This allows you to implement stronger security
	policies by giving you more granular control over which users and groups
	have access to these APIs. You can also enforce the use of tagging and
	control what tag keys and values are set on your resources. When you combine
	tag usage and resource-level IAM policies together, you can ensure your
	instances and volumes are properly secured upon creation and achieve more
	accurate cost allocation reporting. These new features are provided at no
	additional cost.
