obj = s3.bucket('target-bucket').object('target-key')

# the key will now correctly be encoded as 'unescaped/key%20path'
obj.copy_from(bucket:'source-bucket', key:'unescaped/key path')

# the key will now correctly be encoded as 'unescaped/key%20path'
src = S3::Object.new('source-bucket', 'unescaped/key path')
obj.copy_from(src)

# the key will now correctly be encoded as 'unescaped/key%20path'
obj.copy_from('source-bucket/unescaped/key path')

If you have previously worked around this issue, you should remove your code that URL encodes the key.

See related GitHub issue #944.

Feature - Aws::S3 - The #copy_from and #copy_to methods of Aws::S3::Object now accept the source or target bucket and key as a hash with mixed options.

Issue - Aws::S3::Client - Added support for errors returned from Amazon S3 in the body of HTTP 200 responses. Previously only the #complete_multipart_upload operation handled these errors. Extended this to #copy_object and #upload_part_copy.

Issue - Aws::S3::Object - The #presigned_post method now respects the configured custom endpoint.

obj = Aws::S3::Object.new("bucket", "key", endpoint: "http://custom-endpoint.com")
obj.presigned_post.url
#=> "http://bucket.custom-endpoint.com"

Issue - Aws::S3::Presigner - Added validation to #presigned_url to ensure the :key option is not an empty string. This prevents a presigned :get_object URL from becoming a presigned :list_objects request on the bucket.

2.1.19 (2015-09-03)

Feature - Aws::StorageGateway - Adds tagging support for AWS Storage Gateway.
Issue - Aws::InstanceProfileCredentials - Expanded retry logic in the Aws::InstanceProfileCredentials class. Previously this class could raise JSON parse error if the instance metadata service responded but with an invalid JSON document. These errors will be retried 3 times now with backoff.

See related GitHub issue #913.
Feature - Aws::EC2 - Implemented Aws::EC2::VpcPeeringConnection#exists?.

See related GitHub issue #916.
Issue - Aws::EC2 - Added missing pagination configuraiton for the Aws::EC2::Client#describe_vpc_peering_connections operation. Without this, calling #each on the response fails to trigger paging and raises an error.

See related GitHub issue #914.

2.1.18 (2015-08-31)

Feature - Aws::EC2 - Launch Amazon EC2 Spot instances that have the lowest price per unit of capacity using the updated RequestSpotFleet API. Define and set target capacity in any unit including instances, vCPUs, memory, storage, or network throughput. You can specify how much each instance type is worth to your application, and automatically adjust your bid price for each type. This enables you to bid on multiple instance types in a single request and provision cost-effective capacity, regardless of instance type.
Feature - Aws::ElasticLoadBalancing - Added a waiter that will poll until an instance has been deregistered.

See related GitHub issue #793.
Issue - Aws::EC2 - Added a missing #load method for Aws::EC2::NetworkInterfaceAssociation.

See related GitHub issue #890.
Issue - Retries - No longer retrying non-networking errors generated during HTTP handling.

See related GitHub issue #912.

2.1.17 (2015-08-27)

Feature - Aws::ConfigService - Adds support for the #list_discovered_resources API.

2.1.16 (2015-08-25)

Feature - Aws::CodePipeline - Allows specification of an encryption key to use with the artifact bucket when creating and updating a pipeline.
Feature - Logging - Now filtering potentially sensitive request parameters from logs. There is a default list of sensitive request parameters that should be filtered:
```
require 'logger'

kms = Aws::KMS::Client.new(logger: Logger.new($stdout))
kms.encrypt({
  key_id: "key-arn",
  plaintext: "secret-data",
})
```
Produces:
```
I, [2015-08-24T14:53:04.545354 #47906]  INFO -- : [Aws::KMS::Client 400 0.362187 0 retries] encrypt({key_id:"key-arn",plaintext:"[FILTERED]"})
```
You can pass your own list of params to filter when you construct an Aws::Log::Formatter with a custom pattern.

See related GitHub issue #908.
Issue - Aws::PageableResponse::UnsafeEnumerableMethods - respond_to? was not being forwarded to ancestors and it was always retuning false except for #count.

2.1.15 (2015-08-20)

Issue - Aws::Glacier - Resolved an issue with how dates were serialized when specifying start and end dates with an inventory retrieval job.
Feature - Aws::S3 - Added support for event notification filter rules.

2.1.14 (2015-08-12)

Feature - Aws::ElasticBeanstalk - Added support for the two new operations, DescribeEnvironmentHealth, and DescribeInstanceHealth.

Feature - Managed Multipart Copies - Added support to Aws::S3::Object for managed multipart copies of large objects.

obj = Aws::S3::Object.new('bucket', 'key')

obj.copy_from('source-bucket/source-key', multipart_copy: true)
obj.copy_to('target-bucket/target-key', multipart_copy: true)

Feature - Aws::S3::Object - Improved the interfaces for copying objects. There are three new supported signatures for calling #copy_from. Also added the logical pair, #copy_to.

obj = Aws::S3::Object.new('bucket', 'key')

obj.copy_from('source-bucket/source-key')
obj.copy_to('target-bucket/target-key')

obj.copy_from(bucket: 'source-bucket', key: 'source-key')
obj.copy_to(bucket: 'target-bucket', key: 'target-key')

other_obj = Aws::S3::Object('other-bucket', 'other-key')
obj.copy_from(other_obj)
obj.copy_to(other_obj)

For backwards compatibility, the old form of #copy_from still works.

obj.copy_from(copy_source: 'source-bucket/source-key')

Issue - Resources - Resolved an issue with resource actions that source request parameters from data members.

See related GitHub issue #893.

2.1.13 (2015-08-06)

Feature - Aws::SWF - You can now use Amazon Simple Workflow Service to trigger AWS Lambda functions.

2.1.12 (2015-08-04)

Feature - Aws::DeviceFarm - Added support for testing iOS applications with AWS Device Farm. You can now upload your iOS apps and test them on real Apple phones and tablets in the AWS Cloud. You can select from a built-in fuzz test or upload your own tests written with Appium Java JUnit, Appium Java TestNG, Calabash, UI Automation, or XCTest. Results in AWS Device Farm are consistent regardless of the application type (Android, Fire OS, iOS) you upload and test framework you select.
Issue - Aws::EC2 - Updated two Aws::EC2::Client#wait_until waiters to retry instance ID not found errors. The two waiters are:
- :instance_running
- :instance_status_ok
See related GitHub issue #859.

2.1.11 (2015-07-30)

Feature - Aws::RDS - Added support for cluster operations for Aurora.
Feature - Aws::OpsWorks - Added support for ECS clusters to Aws::OpsWorks::Client.

Feature - Virtual Hosted Bucket Urls - You can now generated URLs and pre-signed URLs from Aws::S3 using a CNAME for your virtually hosted buckets.

bucket = Aws::S3::Bucket.new('my.bucket.com')

bucket.url
#=> 'https://s3.amazonaws.com/my.bucket.com'

bucket.url(virtual_host: true)
#=> 'http://my.bucket.com'

bucket.object('key').public_url
#=> 'https://s3.amazonaws.com/my.bucket.com/key'

bucket.object('key').public_url(virtual_host: true)
#=> 'http://my.bucket.com/key'

bucket.object('key').presigned_url(:get)
#=> 'https://s3.amazonaws.com/my.bucket.com/key?...'

bucket.object('key').presigned_url(:get, virtual_host: true)
#=> 'http://my.bucket.com/key?...'

See related GitHub issue #786.

Feature - Signature Version 4 - Added support for signing requests against hosts that do not use the standard port for the given HTTP scheme. This makes it possible to use the signer against test endpoints.

See related GitHub issue #883.

2.1.10 (2015-07-29)

Issue - Aws::CognitoIdentity - Six operations of Aws::CognitoIdentity::Client were whitelisted to be unsigned when sent in version 2.1.9. Two of these operations were incorrectly documented in the API reference and require authentication. Fixed this and added integration tests to ensure they are correctly signed.

See related GitHub issue #882.

2.1.9 (2015-07-28)

Feature - Aws::CloudWatchLogs - Added support for destinations. You can now use destinations to subscribe to cross-account real-time feed of log events from CloudWatch Logs and have it delivered to an Amazon Kinesis stream for custom processing, analysis, or loading to other systems.
Feature - Aws::S3 - Added support for the new long tail storage class and the new storage class headers in the GET and HEAD Object responses.
Feature - Aws::S3 - Added support for the new object delete notification events.
Issue - Aws::Glacier - Aws::Glacier::Account#vaults was not populating the account in the call to list vaults.
Issue - Aws::EC2 - Resolved a regression with serializing Aws::Structure types in Aws::EC2::Client requests. The Aws::Query::EC2ParamBuilder class is responsible for testing protocol specific implementations but it tests with input that is loaded from a JSON document into a vanilla Ruby hash which does not trigger this behavior.

The other protocol builder classes have full unit test suites, while the EC2 param builder did not. A test case has been added to cover this regression.

See related GitHub issue #881.
Feature - KMS Client-Side-Encryption - Added support to Aws::S3::Encryption::Client for using AWS Key Management Service (KMS) to manage master encryption keys.
```
s3_enc = Aws::S3::Encryption::Client.new(kms_key_id: 'kms-key-id')
s3_enc.put_object(bucket:'aws-sdk', key:'secret', body:'data')
s3_enc.get_object(bucket:'aws-sdk', key:'secret').body.read
#=> 'data'
```
This implementation is compatible with objects written by the AWS SDK for Java encryption client.

2.1.8 (2015-07-23)

Feature - Aws::EC2 - Added support for new spot fleet launch specification features.
Feature - Aws::Glacier - Added support for vault locks.
Feature - Aws::ElasticMapReduce - Adds support for Amazon EMR release 4.0.0, which includes a new application installation and configuration experience, upgraded versions of Hadoop, Hive, and Spark, and now uses open source standards for ports and paths. To specify an Amazon EMR release, use the release label parameter (AMI versions 3.x and 2.x can still be specified with the AMI version parameter).

For more information on Amazon EMR release 4.0.0, please visit: https://docs.aws.amazon.com/ElasticMapReduce/latest/ReleaseGuide/emr-release-components.html
Issue - Aws::IAM - Added missing paginator for Aws::IAM::Client#list_policy_versions.

See related GitHub issue #879.
Feature - Waiters - Added two new waiters:
- :instance_profile_exists - Aws::IAM::Client
- :app_exists - Aws::OpsWorks::Client
See related GitHub pull request #866
Issue - Stubbing - Added missing support for stubbing query protocol errors by their error code.

See related GitHub pull request #873
Feature - Aws::CognitoIdentity - The following operations can now be called from Aws::CognitoIdentity::Client without credentials:
- #get_credentialsForIdentity
- #get_id
- #get_open_id_token
- #list_identity_pools
- #unlink_developer_identity
- #unlink_identity
See related GitHub pull request #862

2.1.7 (2015-07-14)

Issue - Aws::Json - Resolved an issue with dumping JSON documents from the standard library JSON implementation.

2.1.5 (2015-07-14)

Feature - Aws::DeviceFarm - Added support for AWS Device Farm.
Feature - Aws::DynamoDBStreams - Added support for Amazon DynamoDB Streams.
Feature - Aws::DynamoDB - Added support for consistent reads with the Scan API.

2.1.4 (2015-07-09)

Feature - Aws::ECS - Amazon EC2 Container Service now supports the UDP protocol.
Feature - Aws::IAM - Adds support for SSH Public Key Operations.
Feature - Aws::SES - Adds support for cross-account sending, which is available through the use of the sending authorization feature.
Feature - Aws::CodeCommit - Adds support for AWS CodeCommit.
Feature - Aws::CodePipeline - Adds support for AWS CodePipeline.

2.1.3 (2015-07-07)

Feature - Aws::AutoScaling - Adds support for step policies. Step scaling policies allow customers to scale their Auto Scaling groups based on the magnitude of the alarm breach, giving them more control over how Auto Scaling responds to an alarm breach and enables them to scale their groups faster.
Feature - Aws::EC2 - Amazon Elastic Block Store snapshot copy support for customer-managed encryption keys.
Feature - Aws::EC2 - Added a Aws::EC2::Route resource class with the associated #delete and #replace operations.
Issue - Aws::DynamoDB - The Aws::DynamoDB::Client#stub_data method will now observe the configured :simple_attributes option and conditionally accept and return simple attribute values.

See related GitHub pull request #863
Issue - Resource - Fixed behavior of #wait_until option max_attempts: nil to match documentation and allow unlimited retries. Default number of retries remains at 10.

See related GitHub pull request #855

2.1.2 (2015-06-24)

Feature - Aws::CloudFront - Can now set :max_ttl and :default_ttl within :cache_behaviors. New API version 2015-04-17.
Feature - Aws::Lambda - Adds java8 as a supported runtime.
Feature - Aws::CognitoSync - Add ConcurrentModificationException error.
Feature - Aws::CognitoIdentity - Add ConcurrentModificationException error.
Feature - Aws::ConfigService - You can now set up AWS Config to record changes for specific resource types.
Feature - Aws::OpsWorks - You can specify which agent version will be used in your AWS OpsWorks managed instances.
Feature - Aws::Glacier - Amazon Glacier now allows you to tag your Amazon Glacier vaults for easier resource and cost management. Tags are labels that you can define and associate with your vaults, and using tags adds filtering capabilities to operations such as AWS cost reports.
Feature - Aws::Redshift - You can create automatic cross-region backups of your KMS encrypted clusters for disaster recovery.

2.1.1 (2015-06-18)

Feature - Aws::ECS - Added support for environment variable overrides.
Feature - XML Parsing - Added support for the new Oga XML parser. This is enabled by default when the gem is present. You can force this by setting the XML parsing engine:
```
Aws::Xml::Parser.engine = :oga
```
Issue - Aws::DynamoDB - Resolved an issue with pageable responses where the paging token values contained attribute values.

See related GitHub issue #843
Issue - Aws::IAM - Added missing paginator configurations for the newer IAM attached policy operations.

See related GitHub issue #841
Issue - PageableResponse - Resolved an issue where Enumerable was not correctly getting mixed into pageable responses.

See related GitHub issue #842
Issue - Shared Credentials - Resolved an issue where the shared credentials provider would fail to parse profiles which contained an inline comment.

See related GitHub issue #837
Feature - Aws::IAM - Added Aws::IAM::User#exists?.

See related GitHub issue #840
Feature - REPL - Added a short-cut inside the aws.rb REPL for accessing a resource from a client.
```
Aws> ec2
#=> #<Aws::EC2::Client>
Aws> ec2.resource
#=> #<Aws::EC2::Resource>
```

2.1.0 (2015-06-11)

Feature - Aws::EC2 - Adds support for Amazon VPC flow logs.
Feature - Aws::ECS - Adds the #update_container_agent method, as well as paginator and waiter support.
Feature - Aws::AutoScaling - Adds the #describe_load_balancers method, and adding the :load_balancer_names parameter to the #update_auto_scaling_group method.
Feature - Fewer gem dependencies - Removed the dependency on the follow two 3rd party gems:
- multi_json
- builder
For JSON parsing and dumping, the SDK will attempt to use the Oj gem if available, and will fall back on JSON from the Ruby standard library.

The only remaining gem dependency is jmespath.
Feature - Service Types - Added struct classes for all AWS data types. Previous versions used anonymous structure classes for response data.
```
Aws::IAM::Types.constants
#=> [:AccessKey, :AccessKeyLastUsed, :AccessKeyMetadata, ...]
```
Each of these data type classes are now fully documented in the api reference docs.
Feature - Examples - The API reference documentation can now load client operation examples from disk. This allows users to contribute examples to the documentation. It also allows for more targeted examples than the auto-generated ones previously used.

Examples are stored inside the examples folder at the root of this repository. https://github.com/aws/aws-sdk-ruby/tree/master/examples
Feature - Documentation - Significant work has gone into API reference documentation. The changes made are based on user feedback. Some of the many changes include:
- More concise syntax examples
- Response structure examples
- Request and response data structures each documented as their own type
- Expanded resource interface documentation on inputs and return values
Expect more documentation improvements.
Feature - Smaller Gem - Reduced the size of the aws-sdk-core gem by removing the AWS API documentation source files from the gemspec. This reduces the total size of the gem by half.

Feature - Stub Data - Added a #stub_data method to Aws::Client that makes it trivial to generate response data structures.

s3 = Aws::S3::Client.new

s3.stub_data(:list_buckets)
#=> #<struct Aws::S3::Types::ListBucketsOutput buckets=[], owner=#<struct Aws::S3::Types::Owner display_name="DisplayName", id="ID">>

You can also provide an optional hash of data to apply to the stub. The data hash will be validated to ensure it is properly formed and then it is applied. This makes it easy to generated nested response data.

s3.stub_data(:list_buckets, buckets:[{name:'aws-sdk'}])
#=> #<struct Aws::S3::Types::ListBucketsOutput
  buckets=[
    #<struct Aws::S3::Types::Bucket name="aws-sdk", creation_date=nil>
  ],
  owner=#<struct Aws::S3::Types::Owner display_name="DisplayName", id="ID">>

Feature - Shared Response Stubs - You can now provide default stubs to a client via the constructor and via Aws.config. This can be very useful if you need to stub client responses, but you are not constructing the client.
```
Aws.config[:s3] = {
  stub_responses: {
    list_buckets: { buckets: [{name:'aws-sdk'}]}
  }
}

s3 = Aws::S3::Client.new
s3.list_buckets.buckets.map(&:name)
#=> ['aws-sdk']
```
See related GitHub issue aws/aws-sdk-core#187
Issue - Response Stubbing - When using response stubbing, pagination tokens will no longer be generated. This prevents stubbed responses from appearing pageable when they are not.

See related GitHub issue #804

Issue - Aws::DynamoDB::Client - Resolved an issue where it was not possible to stub attribute values. You can now stub DynamoDB responses as expected:

ddb = Aws::DynamoDB::Client.new(stub_responses:true)
ddb.stub_responses(:get_item, item: { 'id' => 'value', 'color' => 'red' })
ddb.get_item(table_name:'table', key:{'id' => 'value'})
#=> #<struct Aws::DynamoDB::Types::GetItemOutput item={"id"=>"value", "color"=>"red"}, consumed_capacity=nil>

See related GitHub issue #770

Feature - SSL Peer Verification - Added a method to configure a default SSL CA certificate bundle to be used when verifying SSL peer certificates. V1 did this by default, v2 is now opt-in only.
```
Aws.use_bundled_cert!
```
This method can be very useful for Ruby users on Windows where OpenSSL does not tend to have access to a valid SSL cert bundle.

See related GitHub issue aws/aws-sdk-core#166
Feature - Eager auto-loading - Added a utility method that eagerly loads classes and modules. This can help avoid thread-safety issues with autoload affecting some versions Ruby.
```
# autoload specific services (faster)
Aws.eager_autoload!(services: %w(S3 EC2))

# autoload everything
Aws.eager_autoload!
```
See related GitHub issue #833
Issue - Response Stubbing - Clients with stub_responses: true were still attempting to load credentials from ENV, and the EC2 instance metadata service. Instead, stubbed clients will now construct fake static credentials.

See related GitHub issue #835
Upgrading - Pageable Responses - Due to frequent confusion caused by having every response be decorated as pageable, only operations that can possibly have multiple responses are now decorated.

This ensures that if you call #each on a non-pageable response that an appropriate NoMethodError is raised instead of doing nothing. Simply remove calls to #each if you encounter this unlikely situation.
```
s3 = Aws::S3::Client.new
s3.head_object(bucket:'name', key:'key').each do |page|
end
#=> raises NoMethodError for #each, HEAD object is not pageable
```
This is correctly reflected now in the API reference documentation as well.
Upgrading - Seahorse::Model - The internal representation of AWS API models has been updated. Users digging into internals of the API model will need to update their code to deal with shape references.

This change should not affect users of the public SDK interfaces.

Complex shapes, structures, lists, and maps, now use shape references to nest other shapes. The entire API model now loaded when the service client is defined. This eliminates the need to maintain a complex map of all shapes and define them lazily. This has allows for massive simplifications around API loading, especially when dealing with thread-safety concerns.

2.0.48 (2015-06-04)

Feature - Aws::CloudWatchLogs - Adds support for the #put_subscription_filter, #describe_subscription_filters, and #delete_subscription_filter API operations.
Feature - Aws::CognitoIdentity - Adds support for the #delete_identities API operation, and hiding disabled identities with the #list_identities API operation.
Feature - Aws::StorageGateway - Updated Aws::StorageGateway API to add support for the #list_volume_initiators API operation.
Issue - Aws::DynamoDB - Resolve an issue where IO objects were not properly marshaled, leading to runtime errors.

See related GitHub issue #831
Issue - Aws::S3 - Resolved an issue with the URL decoding of keys in the response to a call to Aws::S3::Client#list_objects.

See related GitHub issue #828

2.0.47 (2015-05-28)

Feature - Aws::Lambda - Lambda now supports specifying an Amazon S3 object as the function zip when creating and updating Lambda functions.

2.0.46 (2015-05-26)

Feature - Aws::EFS - Amazon Elastic File System (Amazon EFS) is a file storage service for Amazon Elastic Compute Cloud (Amazon EC2) instances. Amazon EFS is easy to use and provides a simple interface that allows you to create and configure file systems quickly and easily. With Amazon EFS, storage capacity is elastic, growing and shrinking automatically as you add and remove files, so your applications have the storage they need, when they need it.

2.0.45 (2015-05-21)

Feature - Aws::ElasticTranscoder - Elastic Transcoder now supports additional formats, including MXF, FLAC, and OGA, and additional flexibility for your output audio. You can use these formats to transcode files to the XDCAM format or to a lossless audio format.
Feature - Aws::Kinesis - The Amazon Kinesis API #get_records now includes a new parameter :millis_behind_latest: the number of milliseconds the GetRecords response is from the end of the stream, indicating how far behind real time a consumer is.
Feature - Aws::KMS - Adds the #update_alias API, which allows you to update the association of a key alias from one key to another within a region.
Issue - Aws:SQS - Resolved an issue with the SQS queue poller and changing message visibility timeouts.

See related GitHub issue #821

2.0.44 (2015-05-18)

Issue - Aws::EC2 - Two waiters were added in v2.0.39 and then lost in v2.0.40 in this commit: https://github.com/aws/aws-sdk-ruby/commit/f0fad0a038a4f81b0a697f7c367fd2735d9dd698. The waiters did not get merged upstream and got squashed in the automated release. Reverting this loss. Actual changes have also been merged upstream now.

See related GitHub issue #818
Feature - Aws::ElasticBeanstalk - Added resource names to Aws::ElasticBeanstalk::Client configuration option settings.
Feature - Aws::OpsWorks - Added support for custom auto-scaling based on CloudWatch alarms.
Feature - Aws::EC2 - Added support for the new Spot Fleet API operations.
Issue - Aws::S3 - Resolved a regression with presigned S3 urls where input parameters that are normally sent as x-amz-* headers had to be serialized onto the GET or PUT request. This restores the behavior where they are hoisted onto the request uri as query string parameters.

See related GitHub issue #816

2.0.43 (2015-05-14)

Feature - Aws::DirectoryService - APIs are now supported for the Simple AD and AD Connector directories in AWS Directory Service, enabling you to programmatically create and configure these directories via the AWS SDK for Ruby.
Feature - Aws::EC2 - Added support for Amazon VPC Endpoints for Amazon S3.
Feature - Aws::EC2 - Added support to migrate an Elastic IP Address from EC2-Classic to EC2-VPC.
Feature - Aws::Route53Domains - #check_domain_availability can now return DONT_KNOW when a definitive response has not been received from the registry, such as during domain registry scheduled maintenance periods. UnsupportedTLD is now a potential error from more Route 53 Domains activities.
Feature - Aws::CloudWatchLogs - Added support for the #filter_log_events API for searching logs within a group.
Feature - Aws::CloudFormation - Added new parameters to the return type of the #get_template_summary API.

2.0.42 (2015-05-07)

Feature - Aws::Glacier - Added support for vault access policies.
Issue - Aws::IAM - Added the missing pagination configuration for Aws::IAM::Client#list_policies.

See related GitHub issue #805
Issue - HTTP Handler - Applied a local fix for a Net::HTTP bug. Net::HTTP will retry failed requests when the request method is idempotent, such as HTTP GET, PUT, etc. Unfortunately, Net::HTTP will create a new request, but yield bytes to the same callback after bytes have already been yielded. This causes the response data sink to contain a truncated response, followed by a full response. This results in correct data.

The fix current is to disable idempotent retries until this is fixed upstream.

See related GitHub issue #799
Feature - Aws::S3::Encryption::Client - You can now pass vanilla client constructor options to the encryption client constructor and these will pass through when generating the underlying client. This increases the parity with the vanilla client.

See related GitHub issue #800 and related GitHub issue #801.
Feature - Aws::S3 - Added the ability to pass a block to Aws::S3::Encryption::Client#get_object that yields data as it is decrypted. This increases parity with the vanilla Aws::S3::Client#get_object method.

See related GitHub issue #794.
Issue - Aws::S3 - Resolved an issue were the bucket exists waiter could raise when receiving a 301 permanent redirect from Amazon S3. This happens when the HEAD request is made against a region different from where the bucket exists. Instead this will now cause the :bucket_exists waiter to return a truthy value and not raise.

See related GitHub issue #796.
Issue - Aws::EC2 - The :volume_deleted waiter no longer raises an error on a 400 Aws::EC2::Errors::InvalidVolumeNotFound error. Instead it returns with success.

See related GitHub issue #789.
Feature - Aws::S3 - Added a client-side check to ensure HTTP response bodies are not truncated before all of the expected bytes have been received. This check is performed for all non-HEAD requests where a 'Content-Length' response header is present.

When fewer bytes are returned, then the request is retried up to the configured :retry_limit number limit of attempts. This limit defaults to 3.

2.0.41 (2015-04-27)

Feature - Aws::DynamoDB - Added support to Aws::DynamoDB::Client for key conditions.

2.0.40 (2015-04-23)

Feature - Aws::EC2 - Added support for the new 2015-03-01 API version.
Feature - Aws::IAM - Added support for Aws::IAM::Client#access_key_last_used.
Feature - Aws::CloudSearchDomain - Added support for response expressions.

2.0.39 (2015-04-16)

Feature - Aws::ConfigService - SNS topics on AWS Config's DeliveryChannel are now optional. If the SNS delivery is turned off the last status will be Not_Applicable.
Feature - Aws::CognitoSync - Adds support for Amazon Cognito Events, a new feature that allows developers to run an AWS Lambda function in response to important events in Amazon Cognito. The first event supported is the Sync Trigger event.
Feature - Waiters - Added waiters for:
- Aws::CloudFormation
- Aws::ElastiCache
- Aws::OpsWorks
Expanded waiters for:
- Aws::EC2
Also resolved a few issues in the Aws::CloudFront and Aws::RDS waiters.

See related GitHub issue #758.
Feature - Aws::DynamoDB - Added resource class for Aws::DynamoDB::Table.
Issue - XML Parsing - Resolved an issue where XML string values were not being unescaped.

See related GitHub issue #780.
Issue - Resources - Resolved an issue that prevented the aws-sdk-resources gem from loading resource definitions that have naming conflicts with the Capistrano project.

The #safe_define_method is intenteded to ensure the resource methods do not conflict with methods of Object, such as #send, and #object_id. These are now tested only in local testing but not at runtime. This allows for projects to add functionality to Object without triggering this check.

See related GitHub issue #771.

2.0.38 (2015-04-09)

Upgrading - Aws::Lambda - AWS Lambda is exiting their preview period and has made changes to their control plane APIs. If you are invoking methods outside of Aws::Lambda::Client#invoke_async, you should switch to the Aws::LambdaPreview::Client until you can upgrade.
```
# returns the stable 2015-03-01 API client
lambda = Aws::Lambda::Client.new

# returns the preview API client
lambda = Aws::LambdaPreview::Client.new
```
Feature - Aws::WorkSpaces - Added support for Amazon WorkSpaces.
Feature - Aws::ECS - You can now use the Amazon ECS Service scheduler to manage long-running applications and services. The Service scheduler allows you to distribute traffic across your containers using Elastic Load Balancing.
Feature - Aws::S3 - Added support for resource based permissions for invoking Lambda functions via bucket notifications.

Upgrading - Aws::S3::Client - Deprecated two methods:

Aws::S3::Client#put_bucket_notification
Aws::S3::Client#get_bucket_notification

These methods have been replaced by:

Aws::S3::Client#put_bucket_notification_configuration
Aws::S3::Client#get_bucket_notification_configuration

The method signatures for the old two methods did not correctly allow users to specify multiple topic, queue, and lambda function configurations. The new methods, suffixed by _notification correct these errors. The new methods now also support resource based permissions on notifications to lambda functions.

s3 = Aws::S3::Client.new

# old
s3.put_bucket_notification(
  bucket: 'aws-sdk',

    topic_configuration: { id:'id1', events:[...] },
    queue_configuration: { id:'id2', events:[...] },
    cloud_function_configuration: { id:'id3', events:[...], invocation_role: '...' },
  }
)

# new
s3.put_bucket_notification_configuration(

    	{ id:'id2', events:[...] }
    ],
    lambda_function_configurations: [
    	{ id:'id3', events:[...] }
    ]
  }
)

Notice the :lambda_function_configurations does not take an :invocation_role and that each of the configuration types now takes a list of configurations.

Feature - Aws::MachineLearning - Added support for Amazon Machine Learning.

2.0.37 (2015-04-07)

Feature - Aws::DataPipeline - This release introduces support for AWS Data Pipeline Deactivate feature. You now have the ability to deactivate a running pipeline and activate it later at a time of your choosing.
Feature - Aws::ElasticBeanstalk - Added new #abort_environment_update operation for Elastic Beanstalk. Added a new parameter, :solution_stack_name, to the #update_environment operation for ElasticBeanstalk.
Issue - Aws::IAM - Resolved an issue with Aws::IAM::Resource#policy that would raise an ArgumentError. The resource definition incorrectly supplied the argument as the "PolicyArn" when it should have been simply "Arn".

See related GitHub issue #768.

2.0.36 (2015-04-06)

Issue - Gemspec - Corrected the paths in the gemspec for the API files.

2.0.35 (2015-04-06)

Issue - Xml Parser - Resolved an issue with the recent XML parser update that caused bugs when using Nokogiri. Nokogiri will inconsistently trigger one or multiple text events for XML elements. This seems to be affected by the total size of the XML document.

The XML parser now supports SAX parsing engines that trigger mulitple text events for a single XML element value. Added test where a dummy engine simulates this behavior.

See related GitHub issue #764.
Issue - Response Stubbing - Resolved an issue that prevented response stubs from forcing a nil value for scalars.

See related GitHub issue #763.
Feature - Aws::Resources::Resource - Added support for custom waiters with Aws::Resources::Resource#wait_until.

2.0.34 (2015-04-02)

Feature - Aws::CodeDeploy - AWS CodeDeploy now supports OnPremises deployments.
Feature - Aws::RDS - Adds the #describe_certificates API call, and changes other calls to show the current certificate.
Feature - Aws::EC2 - Added the "D2" family of instance types.
Feature - Aws::ElasticTranscoder - Adds support for PlayReady DRM.
Issue - Endpoints - Resolved an issue where trailing slashes were lost from request parameter values that were bound to the end of the request uri path as a greedy placeholder.

See related GitHub issue #762.
Issue - Aws::SNS - Removed some incorrect identifiers from a few resource methods that were attempting to create Aws::SNS::PlatformApplication objects.
Issue - Aws::Glacier - Corrected a typo in the Aws::Vault#initiate_archive_retrieval method.
Issue - Aws::Errors - Improved the logic for extracting errors from HTTP responses to not fail when the body is empty or if the expected error XML or JSON is not present.

Now falls back on providing a more generic service error based on the HTTP status code.

See related GitHub issue #755.
Feature - Resources - Added #exists? methods to a handful of resource classes. The #exists? method works by polling the exists wait for the resource exactly once. If the waiter is successful, then true is returned, if it fails, then false is returned.

To add additional #exists? methods, a waiter must be added to the resource class as Exists and that waiter must be defined in the *.waiters.json document for that service.
Issue - Presigned URLs - Resolved an issue where x-amz- headers were not being signed as part of a pre-signed URL.

Feature - Aws::S3 - Added Aws::S3::PresignedPost, making it possible to generate a presigned post form for uploading a file from a browser directly to Amazon S3.

s3 = Aws::S3::Resource.new

# post form for a specific object
post = s3.bucket('bucket').object('key').presigned_post(options)
post.fields
#=> { ... }

# force a key prefix
post = s3.bucket('bucket').presigned_post(key_starts_with: '/uploads/')
post.fields
#=> { ... }

See the API PresignedPost documentation for more information and examples.

See related GitHub issue #720.

2.0.31 (2015-03-19)

Feature - Aws::S3 - Added support for requester pays headers to all supported object operations.

See related GitHub issue #694.

Feature - Aws::SNS - Added a utility class that can verify the authenticity of an SNS message.

verifier = Aws::SNS::MessageVerifier.new

verifier.authentic?(message_body)
#=> returns true/false

verifier.authenticate!(message_body)
#=> raises an error on bad message signature

See related GitHub issue #709.

Feature - Aws::SQS - Added Aws::SQS::QueuePoller, a utility class for long polling and processing messages from a queue.
```
poller = Aws::SQS::QueuePoller.new(queue_url)
poller.poll do |msg|
  puts msg.body
end # message deleted here
```
See the API reference documentation for more examples.
Feature - Aws::ElasticTranscoder - API update to support Applied Color SpaceConversion.
Issue - Query Protocol - No longer returning nil for empty maps in query responses. Aws::SQS::Client#get_queue_attributes will always have a hash a resp.attributes instead of a possible nil value.
Issue - Aws::EC2 - Fixed an issue with constructing PlacementGroup resources and added a missing #delete method to RouteTable. See related GitHub pull request #737.

Feature - Aws::EC2 - Added a Aws::EC2::Volume#delete method via pull request.
Issue - Aws::CloudWatchLogs - Resolved an issue that would cause an infinite loop when paginating Aws::CloudWatchLogs#get_log_events. Resolves GitHub issue #712.

2.0.29 (2015-03-04)

Feature - Aws::CognitoSync - Added for for streams. Amazon Cognito streams allows customers to receive near-realtime updates as their data changes as well as exporting historical data. Customers configure an Amazon Kinesis stream to receive the data which can then be processed and exported to other data stores such as Amazon Redshift.
Feature - Aws::CloudSearch - Added support for manual scaling mode and m3 instance types.
Issue - Aws::CloudFormation - Added missing memberName traits to the resource models for the resource classes. This should squelch the duplicate attributes.
Issue - Aws::STS - Resolved an issue that prevented Aws::STS::Client from making unatuthenticated requests to AssumeRoleWithSAML, and AssumeRoleWithWebIdentity. Resolves GitHub issue #725.
Issue - Aws::S3 - Added support for pre-signed PUT object URLs with a content-type. Resolves GitHub issue #721.

Feature - Aws::ECS - Added support for volume mounts.
Feature - Aws::ElasticTranscoder - Added support for warnings and cross region.
Feature - Aws::Route53::Domains - Added paginators.
Issue - Aws::S3 - Expanded logic for yielding data to a given block for more than just HTTP 200 response status codes. This is important so that 206 responses can yield their data. This happens when using range headers.

2.0.26 (2015-02-17)

Feature - API Documentation - Updated the API reference documentation to use the new framless Yard layout.
Issue - Aws::STS - Reverted regionalized endpoints. Customers relying on the Aws::STS::Client using the 'sts.amazonaws.com' endpoint, even when specifying a region such as 'us-west-2' would likely receive errors when they are sent to the 'sts.us-west-2.amazonaws.com' endpoint. This is due to the new endpoints being opt-in via the AWS console. Reverting the change to prevent runtime-errors for customers that have not opted-in.
Issue - Resource Waiters - Resolve an issue where the resource waiter methods were not yielding the waiter object like the client waiters do. This made it impossible to configure the delay and max attempts or callbacks.

2.0.25 (2015-02-17)

Feature - Aws::SSM - Added support fot the new Amazon Simple Systems Management Service.
Feature - Aws::CloudFront - Added support for the 2014-11-06 API version.
Feature - Aws::STS - Added support for the regionalized enpoints.
Issue - Aws::S3 - Resolved an issue where the Aws::S3::Client would raise an unhelpful error when credentials were not set. Now the client will raise an Aws::Errors::MissingCredentialsError when an API operation is called and credentials are not provided. Resolves GitHub issue #708.
Issue - Aws::SharedCredentials - Now ignoring trailing whitespace from the access key id and secret access key values when loading the INI file.
Upgrading - Aws::InstanceProfileCredentials - Increased the default number of attempts to make when loading credentials from the Amazon EC2 instance metadata service before failing from 0 to 5. Also increased the default open and read timeouts from 1 to 5 seconds each. This increases the reliability of loading instance credentials.

These new defaults only affect users who are constructing Aws::InstanceProfileCredential objects directly. If you are using the default credential provider chain, the original defaults remain un-changed.

To revert to default values:
```
Aws.config[:credentials] = Aws::InstanceProfileCredentials.new(
  retries: 0,
  http_open_timeout: 1,
  http_read_timeout: 1
)
```

2.0.24 (2015-02-12)

Feature - Aws::IAM - Added support for named and managed policies.
Feature - Aws::Route53Domains - Added support for tagging operations.

Feature - Aws::DynamoDB - Added support for the new index scan feature to Aws::DynamoDB::Client.
Issue - Aws::S3 - Resolved an issue where calling Aws::S3::Client#get_object with a block would yield error data for non-200 HTTP responses. Resolves GitHub issue #207.
Issue - CloudFormation - Resolved an issue with Aws::CloudFormation resource interfaces for accessing associated "has" associations. Fixes GitHub issue #209.
Issue - Resource Waiters - Resolved an issue with resource waiters raising an error after success. Introduced v2.0.19.pre. Resolves GitHub issue #210.

2.0.22 (2015-02-05)

Issue - Aws::EC2 - Fixed the return value from Aws::EC2::Resource#create_volume.
Upgrading - Aws::SQS::Resources - Removed resource interfaces for Aws::SQS. These are unstable, so they have been removed for the public release of aws-sdk-resources.

2.0.21 (2015-01-27)

Feature - Aws::ImportExport - Added support for the new get shipping label API operation.
Feature - Aws::DynamoDB - Added support for online indexing.
Issue - Response Stubbing - Resolved an issue where the response stubbing plugin would not correctly populate the response target for streaming API calls, such as Aws::S3::Client#get_object. Fixes GitHub issue #197.
Issue - Aws::EC2 - Added missing paginator configuration for Aws::EC2::Client#describe_instances. Fixes GitHub issue #196.

2.0.20 (2015-01-20)

Feature - Aws::EMR - Added support for Custom security groups feature for Amazon Elastic MapReduce (EMR). Custom security groups allow you to define fine grain control over the security rules for your EMR cluster by specifying your own Amazon EC2 security groups.
Feature - Aws::CognitoIdentity - Amazon Cognito now allows developers to save the association between IAM roles and an identity pool via the #set_identity_pool_roles API. Identity pools with IAM roles associated can use the new #get_credentials_for_identity API to retrieve a set of temporary credentials based on the associated roles. Roles associated to the pool must be properly configured to work with Amazon Cognito. Developers can still use the #get_open_id_token API in conjunction with STS #assume_role_with_web_identity API if there are no roles associated with their pool.
Feature - Aws::AutoScaling - Added support to Aws::AutoScaling::Client for classic link.

2.0.19 (2015-01-15)

Feature - Aws::ElasticTranscoder - Updated Client to support the new encryption features.
Feature - Waiters - Added support for version 2 of the waiters definition format.

Issue - Instance Profile Credentials - Resolved an issue where instance profile credentials would never load if the first attempt fails. See GitHub issue #193.
Issue - Aws::S3::Object - Resolved an issue with #upload_file where options intended for #initiate_multipart_upload are being passed along to individual #upload_part API calls. Fixes GitHub issue #684.

2.0.18 (2015-01-08)

Feature - Aws::CloudHsm - Added support for the new Amazon CloudHSM service.
Feature - Aws::EC2 - Added support for the new Amazon EC2 Container Service.
Feature - Aws::EC2 - Added support for Amazon EC2 classic link.
Feature - Aws::RDS - Updated to the latest API version, 2014-10-31, adding support for the new #describe_pending_maintenance_actions operation to Aws::RDS::Client.
Issue - Aws::S3 - Resolved an issue with Aws::S3::Client#get_bucket_location. Fixes GitHub issue #185.

Upgrading - Aws::IAM - Moved Aws::Role#update_assume_role_policy to a new resource class.

iam = Aws::IAM::Resource.new

# old
iam.role('name').update_assume_role_policy(policy_document:'...')

# new
iam.role('name').assume_role_policy.update(policy_document:'...')

Upgrading - Aws::IAM - Renamed two methods on Aws::IAM::MFADevice.
- #enable -> #associate
- #disable -> #disassociate
Upgrading - Aws::IAM - Removed Aws::IAM::AccountSummary. Calling Aws::IAM::Resource#create_account_summary no longer returns a resource object.
```
iam = Aws::IAM::Resource.new

# old
iam.create_account_alias(account_alias:'alias')
iam.account_alias('alias').delete

# new (no need to specify the alias when deleting)
iam.create_account_alias(account_alias:'alias')
iam.delete_account_alias
```
Also, the Aws::IAM::Resource#account_aliases method has been removed. There is no replacement. IAM does not permit more than one account alias.

2.0.17 (2014-12-22)

Feature - Aws::S3::Encryption::Client - Added new options to Aws::S3::Encryption::Client#get_objet. You can now pass the following options to #get_object:
- :envelope_location
- :instruction_file_suffix
Passing these options override the default values determined during construction of the Aws::S3::Encryption::Client.

2.0.15 (2014-12-17)

Feature - Client-Side Encryption - Added Aws::S3::Encryption::Client which allows users to perform PUT and GET Object operations against Amazon S3 while encrypting and decrypting the object client-side.

require 'openssl'
key = OpenSSL::Cipher.new("AES-256-ECB").random_key

# vanilla S3 client
s3 = Aws::S3::Client.new(region:'us-west-2', credentials: ...)

# encryption client
s3e = Aws::S3::Encryption::Client.new(encryption_key: key, client: s3)

# round-trip an object, encrypted/decrypted locally
s3e.put_object(bucket:'aws-sdk', key:'secret', body:'handshake')
s3e.get_object(bucket:'aws-sdk', key:'secret').body.read
#=> 'handshake'

# attempt to read the encrypted object without the encryption client
s3.get_object(bucket:'aws-sdk', key:'secret').body.read
#=> "... cipher text ..."

You can configure a :key_provider to the encryption client to allow for using multiple decryption keys. See the Aws::S3::Encryption::Client API documentation for more information.

Feature - Async Handlers - The HTTP handler now signals the response object on HTTP headers, data, complete and errors. This allows downstream handlers to handler HTTP events as they happen. As a result, all handlers calling #on(...) on the response object no longer need to block on the HTTP response being complete.
Feature - Aws::DynamoDB - Now calculating a CRC32 checksum of the HTTP response body on every request and comparing it against the value returned by Amazon DynamoDB in the X-Amz-Crc32 header. Failed checksums trigger an automatic retry.

You can disable this checksum by passing compute_checksums: false to the Aws::DynamoDB::Client constructor:
```
ddb = Aws::DynamoDB::Client.new # verify crc32 checksums
ddb = Aws::DynamoDB::Client.new(compute_checksums: false) # disabled
```

subscription = sns.topic(topic_arn).subscription(subscription_arn)

# new
subscription = sns.subscription(subscription_arn)

2.0.13 (2014-12-08)

Feature - Aws::SQS - Added support for purging queues.
Feature - Aws::OpsWorks - You can now use AWS OpsWorks with existing EC2 instances and on-premises servers.
Issue - Aws::CloudFront - Resolved an issue that prevented the client paginators from working. Fixes #169.

2.0.12 (2014-12-04)

Feature - Aws::S3 - Added a #public_url method to Aws::S3::Object. Use this method to generate a URL that can be pasted into the browser for objects with a "public-read" ACL.
```
s3 = Aws::S3::Resource.new(region:'us-west-2')
s3.bucket('aws-sdk').object('key').public_url
#=> "https://aws-sdk.s3-us-west-2.amazonaws.com/key"
```
Feature - Aws::Route53 - Added support to Aws::Route53::Client for the new UpdateHostedZoneComment operation.
Feature - Aws::IAM - Added support to Aws::IAM::Client for the new GetAccountAuthorizationDetails operation.

Upgrading - Aws::IAM - Renamed Aws::IAM::User#create_access_key to #create_access_key_pair. Also returning an AccessKeyPair now instead of an AccessKey.
```
key_pair = iam.user('username').create_access_key_pair
key_pair.id     #=> access key id
key_pair.secret #=> secret access key
```

2.0.10 (2014-11-20)

Feature - Aws::Redshift - Added support for AWS Key Management Service (KMS) integration.
Issue - Aws::KMS - Corrected the paginators for Aws::KMS::Client.
Issue - Aws::IAM - Corrected the signature version 4 signing name when using Aws::IAM::Client in the us-gov-west-1 region. Fixes #159
Issue - Aws::S3 - Resolved an issue when making a GET Object request against an object encrypted with AWS KMS. Automatically using signature version 4 for GET requests in all known regions. When the region is not known, a best effort is made to determine the region. Fixes #157.
Issue - Aws::S3 - The Aws::S3::Client#get_bucket_location operation will no longer use DNS addressing and will instead use path-addressing for the bucket name. This avoids signature errors for v4-only regions when the classic endpoint is used with a v2 signature.
Issue - Aws::S3 - Fixed a bug in #put_object_acl serialization. Fixes #160.

bucket = S3::Resource.new.bucket('aws-sdk-versioned')

# enumerate every versioned object in a bucket
bucket.object_versions.each do |obj_version|
  # ...
end

# delete every object version in a bucket (two options)
bucket.object_versions.delete
bucket.clear!

# delete a bucket and all of its objects

# before
queue.attributes['CreatedTimestamp'] #=> '1413825896' (epoc seconds)
queue.attributes['DelaySeconds'] #=> '60' (string seconds)
queue.attributes['QueueArn'] #=> 'arn'

# after
queue.created_timestamp #=> 2014-10-20 10:24:56 -0700 (Time obj)
queue.delay_seconds #=> 60 (integer seconds)
queue.arn #=> 'arn' (without extra queue_ prefix on method)

Feature - Assume Role Credentials - Added a credentials class that assumes a role via Aws::STS::Client#assume_role. Credentials are automatically refreshed before the expire:
```

InstanceProfileCredentials.new(retries:3)
```
Feature - Stubbing Client Responses - Added support for stubbing client responses without making API calls. In addition to the default fake resposnes, you can provide stub data and errors:
```
s3 = Aws::S3::Client.new(stub_responses: true)
s3.stub_responses(:list_buckets, buckets:[{name:'aws-sdk'}])
s3.list_buckets.buckets.map(&:name)
#=> ['aws-sdk']
```
See API docs for Aws::Client#stub_responses for more information.
Feature - S3 Waiters - Added resource waiters for S3::Bucket and S3::Object.
Issue - Aws::SQS::Client#receive_message - Resolved an issue where the response from #receive_message could return nil for #messages. It now always returns an array.
Issue - Waiters - Resolved an issue with Aws::EC2::Client#wait_until and the volume status waiters. These were polling the incorrect API method causing #wait_until to raise an error. See issue #129.

2.0.1 (2014-09-29)

Feature - Aws::CognitoIdentity::Client - Added support for Cognito developer identities.
Issue - Region - Now giving a helpful error message when a region is not configured. Was previously exposing a URI parse error message.

2.0.0 (2014-09-25)

Feature - S3 Presigned URLs - Added support for pre-signed URLs for Amazon S3.

presigner = Aws::S3::Presigner.new
presigner.presigned_url(:put_object, bucket:'aws-sdk', key:'key')
#=> "https://aws-sdk.s3.amazonaws.com/key?..."

Feature - Autoload - Service modules / classes now autoload upon first use. This speeds up gem load time significantly.
Feature - Resources - Resource constructors now pass additional options to the Client constructor when :client is not provided.
Issue - SigV4 - Resolved an issue with how version 4 signatures generated the normalized querystring. Query params without a value now consistantly receive a trailing =.
Issue - SigV4 - Resolved an issue with how version 4 signatures generated the normalized querystring. Query params are now sorted by name.

2.0.0.rc16 (2014-09-11)

Feature - Waiters - Added a new feature called waiters. Waiters poll a single API until a certain condition is matched. Waiters are invoked by a name and can be configured.
```
# client waiter
ec2 = Aws::EC2::Client.new
ec2.wait_until(:instance_stopped, instance_ids:['i-12345678'])

# resource waiters
instance = Aws::EC2::Instance.new(id:'i-12345678')
instance.start
instance.wait_until_running
```
See the client API documentation for #wait_until and the resource API documentation for #wait_until_{condition}.
Feature - Resources - Merged in resources branch. You can now use resource-oriented interfaces with Aws::S3, Aws::EC2, Aws::SQS, Aws::SNS, Aws::Glacier, and Aws::IAM.
Feature - New Gems - Organized the repository into three gems, aws-sdk, aws-sdk-resources, and aws-sdk-core. Moved library and test files each into their respective gem directories.
Issue - Error Class Names - Resolved an issue that could raise a NameError, "wrong constant name" at runtime in response to a service error. Fixes #97.
Issue - Aws::CloudSearchDomain::Client - Resolved an issue that would cause the Aws::CloudSearchDomain::Client constructor to raise an error when Aws.config[:region] is set. Fixes #103.
Issue - Shared Credentials - Resolved an issue where an error was raised if the shared AWS credentials file is present and is empty or missing the default profile. Fixes #104.

2.0.0.rc15 (2014-08-14)

Feature - Aws::S3::Client - Enabling url-encoding of Amazon S3 keys by default. Keys are decoded before response data is returned. See #95.
Feature - Aws::ElasticLoadBalancing::Client - Added support for the new tagging operations.
Feature - Aws::CloudSearch::Client - Will now sign requests when credentials are provided. You can continue making unauthenticated requests if you do not configure credentials to the client.
Feature - Coverage - Now generating coverage reports during Travis builds and reporting via Coveralls.io.
Upgrading - Aws::DynamoDB::Client - Added a plugin that simplifies working with DynamoDB attribute values. Enabled by default, to restore default behavior, use :simple_attributes => false.
Issue - Documentation - Now loading API files with UTF-8 encoding. See #92.

2.0.0.rc14 (2014-08-05)

Upgrading - Client Classes - Versioned client classes removed, e.g. Aws::S3::Client::V20060301.new is now Aws::S3::Client.new The :api_version constructor option is no longer accepted.
Upgrading - Aws Module - Helper methods on Aws for client classes deprecated; For example, calling Aws.s3 will generate a deprecation warning. Use Aws::S3::Client.new instead. Helpers will be removed as of v2.0.0 final.
Upgrading - Config - When configuring an :endpoint, you must now specify the HTTP scheme, e.g. "http://localhost:3000", instead of "localhost:3000".

2.0.0.rc1 - 2.0.0.rc13
