 * <h3>Repositories</h3>

 * <p>In Maven, <dfn>{@linkplain org.apache.maven.api.Repository repositories}</dfn> are locations where project artifacts (such as JAR files, POM files, and other
 * resources) are stored and retrieved. There are two primary types of repositories:<ul>

With a few small exceptions (below), OkHttp 4.x is both binary- and Java source-compatible with
OkHttp 3.x. You can use an OkHttp 4.x .jar file with applications or libraries built for OkHttp 3.x.

OkHttp is **not** source-compatible for Kotlin callers, but upgrading should be automatic thanks to

    Maven 4 Plugin descriptor, stored in {@code META-INF/maven/plugin.xml} in a plugin's jar artifact.
    This descriptor is generally using the information contained in the annotations of the plugin api.

as a JVM library that _detects_ Android capabilities at runtime, but that doesn't offer
Android-specific APIs. With this release we're starting to publish OkHttp as an AAR for Android
users in addition to our existing JAR for JVM users.

This first Android-specific artifact adopts Android's `assets` mechanism to embed the public suffix
data. We will build more Android integration in future releases.

 * Fix: Correct bug where HTTPS POST requests were always automatically buffered.
 * Fix: Honor read timeout when parsing SPDY headers.
