 - Added support for formatting & coloring of JSON bodies preceded by non-JSON data (e.g., an XXSI prefix). ([#1130](https://github.com/httpie/httpie/issues/1130))
 - Added `--response-charset` to allow overriding the response encoding for terminal display purposes. ([#1168](https://github.com/httpie/httpie/issues/1168))
 - Added `--response-mime` to allow overriding the response mime type for coloring and formatting for the terminal. ([#1168](https://github.com/httpie/httpie/issues/1168))
