## Design Documentation

### New Features

**In Development**

*Development on these features has started. No date can be shared for
when these features will be completed, and their end state may vary
significantly from the state proposed in these documents.*

* [S3 Transfer Manager](services/s3/transfermanager/README.md) -
  Simplifies uploading and downloading of objects to and from Amazon S3.

**Proposed**

*These features are being proposed for development. These features will
either transition to "In Development" when development begins, or
"Rejected" if it is decided that these features will not be implemented.
No date can be shared for when the fate of these features will be
decided.*

* [Event Streaming Alternate Syntax](core/event-streaming/alternate-syntax/README.md)
  \- Simplifies interacting with event streaming services for
  non-power-users.

  interrupted by a network error.
* [Tagged Unions](core/tagged-unions/README.md)

design elements or features can be implemented incrementally based on customer 
demand.*
