This release updates the SDK's configuration and bug fixes.

go get -u github.com/aws/aws-sdk-go/...

Migrating to this change you'll need to add a session.Session to your application. The session will be used in each place a service client is created. Naively this can be s3.New(session.New()) instead of the previous s3.New(nil). If the aws.Config value was being passed in to the service client the code would become, s3.New(session.New(), cfg). If you used default.DefaultConfig you can replace this logic with a new session and set merge in the config which was beign set to the global default value. Like session.New(myCfg) or:

sess := session.New()
sess.Config.LogLevel = aws.LogLevel(aws.Debug)

Examples:

    // Create a session with the default config and request handlers.
    sess := session.New()

    // Create a session with a custom region
    sess := session.New(&aws.Config{Region: aws.String("us-east-1")})

    // Create a session, and add additional handlers for all service
    // clients created with the session to inherit.
    sess := session.New()
    sess.Handlers.Build.pushBack(func(r *request.Handlers) {
        // Log every request made and its payload
        logger.Println("Request: %s/%s, Payload: %s", r.ClientInfo.ServiceName, r.Operation, r.Params)
    })

    // Create a S3 client instance from a session
    sess := session.New()
    svc := s3.New(sess)

    // Create a S3 client with additional configuration
    svc := s3.New(sess, aws.NewConfig().WithRegion("us-west-2"))

In addition to this change there were a few other changes in this update.

• aws/service.Service was renamed to aws/client.Client.
• aws/service/serviceinfo.ServiceInfo was renamed to aws/client/metadata.ClientInfo
• aws.DefaultRetries was renamed to aws.UseServiceDefaultRetries
• aws/ec2metadata now takes a session and aws.Config like all other service clients
• aws/credentails/ec2rolecreds.EC2RoleProvider now requires an ec2metadata.EC2Metadata and will not default to creating one.
• service/s3/s3manager.Downloader now requires a S3 service client instance, and also takes functional options for setting the Downloader's options.
• service/s3/s3manager.Uploader now requires a S3 service client instance, and also takes functional options for setting the Uploader's options.

This release of the SDK supports the following API versions:
