himself as he came, `Oh! the Duchess, the Duchess! Oh! won't she
be savage if I've kept her waiting!'  Alice felt so desperate
that she was ready to ask help of any one; so, when the Rabbit
came near her, she began, in a low, timid voice, `If you please,
sir--'  The Rabbit started violently, dropped the white kid

## Introduction {#intro}

Go's emphasis on backwards compatibility is one of its key strengths.
There are, however, times when we cannot maintain complete compatibility.

## Version 5.0.0-alpha.7

_2022-04-26_

**This release introduces new Kotlin-friendly APIs.** When we migrated OkHttp from Java to Kotlin in
OkHttp 4.0, we kept our Java-first APIs. With 5.0 we're continuing to support Java and adding
additional improvements for Kotlin users. In this alpha we're excited to skip-the-builder for

   * The page replacement algorithm's data structures are kept casually consistent with the map. The
   * ordering of writes to a segment is sequentially consistent. An update to the map and recording

   * granularity. For example, access queues and write queues are kept per segment when they are
