 *  New: Require Kotlin 1.3.40.
 *  New: Change the Kotlin API from `File.toRequestBody()` to `File.asRequestBody()` and
    `BufferedSource.toResponseBody()` to `BufferedSource.asResponseBody()`. If the returned value
    is a view of what created it, we use _as_.
 *  Fix: Permit response codes of zero for compatibility with OkHttp 3.x.
 *  Fix: Change the return type of `MockWebServer.takeRequest()` to be nullable.

 * [application interceptor][OkHttpClient.interceptors] or as a [OkHttpClient.networkInterceptors].
 *
 * The format of the logs created by this class should not be considered stable and may
 * change slightly between releases. If you need a stable logging format, use your own interceptor.

Change Log
==========

## Version 4.x

See [4.x Change log](https://square.github.io/okhttp/changelogs/changelog_4x/) for the stable version changelogs.

## Version 5.0.0-alpha.14

_2024-04-17_

 *  Breaking: Move coroutines extensions to okhttp3.coroutines. Previously this artifact shared the
    `okhttp3` package name with our core module, which is incompatible with the Java Platform Module
    System.

## Version 2.0.0

This release commits to a stable 2.0 API. Read the 2.0.0-RC1 changes for advice
on upgrading from 1.x to 2.x.

_2014-06-21_

 *  **API Change**: Use `IOException` in `Callback.onFailure()`. This is
    a source-incompatible change, and is different from OkHttp 2.0.0-RC2 which
    used `Throwable`.

      if (c < '0' || c > '9') break
      if (value == 0 && groupOffset != i) return false // Reject unnecessary leading '0's.
      value = value * 10 + c.code - '0'.code
      if (value > 255) return false // Value out of range.
      i++
    }
    val groupLength = i - groupOffset
    if (groupLength == 0) return false // No digits.

    // We've successfully read a byte.
    address[b++] = value.toByte()

     * @param weight relative proportion of priority in `[1..256]`.

     * security. ECDSA keys are noticeably faster than RSA keys.

     * This is the default configuration and has been since this API was introduced in OkHttp
     * 3.11.0. Note that the default may change in future releases.
