## Courier v0.3.1 (2017-08-23)
Quick update to the v0.3 release fixing some issues with the initial version.
### Fixes
* Fixed the generated [`Responder`] impl to actually generate MessagePack responses when the
`msgpack` feature is enabled, and to not generate JSON responses when the `json` feature is
disabled. ([#1](https://github.com/excaliburHisSheath/courier/pull/1))
* Fixed the generated [`Responder`] impl to check the [`Accept`] header to determine what format
to use for the response body. ([#1](https://github.com/excaliburHisSheath/courier/pull/1))
## Courier v0.3 (2017-08-22)
Initial release supporting v0.3.x of Rocket. Provides support for deriving [`FromData`] and
[`Responder`] for any types that implement [`serde::Deserialize`] and [`serde::Serialize`],
respectively. Also supports using both [JSON] and [MessagePack] formats for data transfer.
