**OkHttp now supports Happy Eyeballs ([RFC 8305][rfc_8305]) for IPv4+IPv6 networks.** It attempts
both IPv6 and IPv4 connections concurrently, keeping whichever connects first.

**We’ve improved our Kotlin APIs.** You can skip the builder:

```kotlin

        FileSystemInformation info1 = response.getInfo();

        // Second read with different data
        buffer = prepareAllocationInfoBuffer();
        buffer[8] = 10; // Change some data

        int bytesRead2 = response.readDataWireFormat(buffer, 0, 20);
        FileSystemInformation info2 = response.getInfo();

        // Info should be updated

    // Source of length 5
    AppendableByteSource source = new AppendableByteSource(newPreFilledByteArray(5));

    // Slice it starting at offset 10.
    ByteSource slice = source.slice(10, 5);

    // Open a stream to the slice.
    InputStream in = slice.openStream();

    // Append 10 more bytes to the source.
    source.append(newPreFilledByteArray(5, 10));
