undefined method `batch_change_message_visibility' for #<AWS::SQS::Queue:0x7fba7a7eec30> (NoMethodError)
===

I'm trying to write a ruby script to change a message error but I'm getting the error batch_change_message_visibility is not a defined method.
Here is the code :

    require 'rubygems'
    require 'aws-sdk'
    
    sqs = AWS::SQS.new(
        :access_key_id => access_key,
        :secret_access_key => access_secret)
    
    queue = sqs.queues.named(queue_name)
    
    messages = []
    messages << { :message => message_handle, :visibility_timeout => 5 }
    queue.batch_change_message_visibility(messages)


Any idea ? Thanks !
