Release Notes

square/okhttp (com.squareup.okhttp3:okhttp)

v5.0.0-alpha.16

2025-05-29

• Fix: The previous release would crash when running on Robolectric. We didn't anticipate
  running our Android artifact on the JVM platform!

v5.0.0-alpha.15

2025-05-28

This release introduces separate JVM and Android artifacts. Until now, we've distributed OkHttp
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.

The okhttp-android artifact first introduced in 5.0.0-alpha.7 is no longer available:

• The AndroidAsyncDns class moved to the okhttp artifact.
• The AndroidLogging class is no longer necessary. LoggingEventListener and
  HttpLoggingInterceptor write to logcat by default.

The rest of this release is our highest-quality release yet. Though we continue to use the word
alpha in the version name, the only unstable thing in it is some non-final APIs tagged
@ExperimentalOkHttpApi. You can safely use this release in production.

• Fix: Attempt to read the response even if sending the request failed. This makes it possible
  to handle response statuses like HTTP/1.1 431 "Request Header Fields Too Large.

• Fix: Handle multiple 1xx responses.

• Fix: Address a performance bug in our internal task runner. We had a race condition that could
  result in it OkHttp starting a thread for each queued task, even when a single thread could run
  all of them.

• Fix: Address a performance bug in MultipartReader. We were scanning the entire input stream
  for a delimiter when we only needed to scan enough to return a result.

• Fix: Don't double-compress the public suffix database. OkHttp is usually distributed in a
  compressed file (like a JAR or APK), so compressing its internal data was redundant.

• Fix: Call ProxySelector.connectFailed() when a connection's initial TCP handshake fails.

• Fix: Change the signature of Dispatcher to accept a nullable ExecutorService. Changing this
  parameter to be non-null was an unintended signature change in OkHttp 4.0.

• New: EventListener.retryDecision() is called each time a request fails with an IOException.
  It notifies your listener if OkHttp will retry.

• New: EventListener.followUpDecision() is called each time a response is received. It notifies
  your listener if OkHttp has decided to make a follow-up request. Some common follow-ups are
  authentication challenges and redirects.

• New: Handy constants for Headers.EMPTY, RequestBody.EMPTY, and ResponseBody.EMPTY.

• New: OkHttp now calls StrictMode.noteSlowCall() when initializing TLS on Android. Use
  StrictMode to detect if your OkHttpClient is being initialized on the main thread.

• Upgrade: [Okio 3.12.0][okio_3_12_0].

• Upgrade: [Kotlin 2.1.21][kotlin_2_1_21].

• Upgrade: [kotlinx.coroutines 1.10.2][coroutines_1_10_2]. This is used by the optional
  okhttp-coroutines artifact.

• Upgrade: [AndroidX Startup 1.2.0][startup_1_2_0]. The Android variant of the okhttp artifact
  now depends on this. This is a new dependency.

• Upgrade: [AndroidX Annotation 1.9.1][annotation_1_9_1]. As above, the Android variant of the
  okhttp artifact now depends on this. This is also a new dependency.
