New Features

Change Description
Amazon CloudWatch

Added support for Amazon CloudWatch (AWS::CloudWatch). Special thanks to community member yyuu for his contribution that enables CloudWatch suport.


Amazon DynamoDB now accepts requests signed with Signature Version 4. The aws-sdk no longer requests a session from AWS Security Token Sevice before making requests to Amazon DynamoDB.


You can now provide a serial number and token code when getting session credentials from AWS Security Token Service.

sts =
session = sts.new_session(:serial_number => '...', :token_code => '...')
