## [Responses](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-response/)

The response answers the request with a code (like 200 for success or 404 for not found), headers, and its own optional body.

## Version 1.0.2

_2013-05-11_

 * Fix: Remove use of Java 6-only APIs.
 * Fix: Properly handle exceptions from `NetworkInterface` when querying MTU.
 * Fix: Ensure MTU has a reasonable default and upper-bound.


## Version 1.0.1

_2013-05-06_

 * Correct casing of SSL in method names (`getSslSocketFactory`/`setSslSocketFactory`).


## Version 1.0.0

_2013-05-06_

    Nullability was previously ambiguous and lenient but now the compiler will
    enforce strict null checks.

 *  New: The response message is now non-null. This is the "Not Found" in the
    status line "HTTP 404 Not Found". If you are building responses
    programmatically (with `new Response.Builder()`) you must now always supply
    a message. An empty string `""` is permitted. This value was never null on
