The preview release of Version 2 of the AWS SDK for Ruby is now available. If you are utilizing Bundler with standard best practices, you should not encounter any issues with the release of the aws-sdk gem version 2. This article aims to inform you of some essential points to consider.

Installing the V2 Preview Release

You can install the V2 preview release of the AWS SDK for Ruby by using the following command:

$ gem install aws-sdk --pre

When using Bundler, it is necessary to specify the complete version until the preview status is lifted:

gem 'aws-sdk', '2.0.0.pre'

Locking Your Dependencies

The V2 Ruby SDK is not backward compatible with the V1 Ruby SDK. If you have a Bundler dependency on aws-sdk and do not specify a version, you may encounter complications when the final 2.0 version is released. To avoid issues from this major version change, ensure you include a version dependency in your Gemfile:

gem 'aws-sdk', '< 2.0'

Alternatively, you can switch your gem dependency from aws-sdk to aws-sdk-v1:

gem 'aws-sdk-v1'

The AWS SDK for Ruby adheres to semantic versioning, enabling users to update within the same major version with confidence that there are no backward-incompatible changes. If any such changes do occur, they will be categorized as bugs.

Utilizing Both Versions in One Application

The V1 and V2 Ruby SDKs operate under different namespaces, allowing only one version of a single gem to be loaded. The V1 Ruby SDK is now published as a separate gem, enabling users to load both versions if necessary. Furthermore, the V2 SDK employs a different root namespace to prevent any conflicts:

# in your Gemfile
gem 'aws-sdk-v1'
gem 'aws-sdk', '2.0.0.pre'

In your application, you will need to require both versions:

require 'aws-sdk-v1'
require 'aws-sdk'

# v1 uses the AWS module, v2 uses the Aws module
s3_v1 = AWS::S3::Client.new
s3_v2 = Aws::S3::Client.new
