Code Cleanup
------------

IntelliJ and Android Studio offer a **Code Cleanup** feature that will automatically update
deprecated APIs with their replacements. Access this feature from the _Search Anywhere_ dialog
(double-press shift) or under the _Analyze_ menu.

We’ve included deprecated APIs in OkHttp 4.0 because they make migration easy. We will remove them

MockWebServer is used for firstly for internal testing, and for basic testing of apps using OkHttp client.
It is not a full featured HTTP testing library that is developed standalone. It is not being actively developed
for new features. As such you might find your needs outgrow MockWebServer and you may which to use a
more full featured testing library such as [MockServer](https://www.mock-server.com/).
