## DynamoDB Indexes Enhancements

For a majority of users, the decreased provisioned throughput for build and release DynamoDB tables will result in a monthly savings!

Thanks [@frsechet](https://github.com/frsechet) for the improvement!  
For more info see PR [#736](https://github.com/convox/rack/pull/736): changed provisioned throughput for DynamoDB indexes.

## Git Submodules Checkout

This enhancement allows `convox build` to pull/update a repo’s submodules, if any.

Thanks [@mfine](https://github.com/mfine) for the improvement!  
For more information see PR [#732](https://github.com/convox/rack/pull/732): Update submodules on git checkout

## Autoscaling Improvements

PR [#737](https://github.com/convox/rack/pull/737) made some improvements for [scaling](https://convox.com/docs/scaling/) a rack. With the rack `Autoscale` parameter enabled,  
there is no need to use the `--count` option to increase the instance count. A Rack can scale its own instance count based on the needs of the containers it provisions.
