1.13.0

Release date: 2014-05-08

A special thanks to (@johnbartels) for his help with the consecutive checks feature.

• It is now possible to scale down after x consecutive checks where Dynamic DynamoDB have seen a need for scaling down. This will make it even easier to target the times during the day where you want to scale down. See the num-read-checks-before-scale-down and num-write-checks-before-scale-down options. (#148)
• In addition to the consecutive checks feature we have support for resetting the consecutive checks counter on certain consumption percentages using num-read-checks-reset-percent and num-write-checks-reset-percent. In the example below we would be able to avoid the second scale down by setting a reset percentage that was slightly higher than the consumption spikes.

• You can now run Dynamic DynamoDB once instead of looping using the --run-once command line option (#152)
