Release Notes

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

v5.2.1

2025-10-09

• Fix: Don't crash when calling Socket.shutdownOutput() or shutdownInput() on an SSLSocket
  on Android API 21 through 23. This method throws an UnsupportedOperationException, so we now
  catch that and close the underlying stream instead.

• Upgrade: [Okio 3.16.1][okio_3_16_1].

v5.2.0

2025-10-07

• New: Support [HTTP 101] responses with Response.socket. This mechanism is only supported on
  HTTP/1.1. We also reimplemented our websocket client to use this new mechanism.

• New: The okhttp-zstd module negotiates [Zstandard (zstd)][zstd] compression with servers that
  support it. It integrates a new (unstable) [ZSTD-KMP] library, also from Square. Enable it like
  this:

  val client = OkHttpClient.Builder()
    .addInterceptor(CompressionInterceptor(Zstd, Gzip))
    .build()

• New: Support the QUERY HTTP method. You will need to set the Request.cacheUrlOverride
  property to cache calls made with this method. The RequestBody.sha256() may be helpful here;
  use it to compose a cache URL from the query body.

• New: Publish events when calls must wait to execute. EventListener.dispatcherQueueStart()
  is invoked when a call starts waiting, and dispatcherQueueEnd() is invoked when it's done.

• New: Request.toCurl() returns a copy-pasteable [curl] command consistent with Chrome’s and
  Firefox’s ‘copy as cURL’ features.

• New: Support [JPMS]. We replaced our Automatic-Module-Name metadata with proper
  module-info.java files.

• Fix: Recover gracefully when worker threads are interrupted. When we introduced fast fallback in
  OkHttp 5.0, we started using background threads while connecting. Sadly that code didn't handle
  interruptions well. This is now fixed.

• Upgrade: [Kotlin 2.2.20][kotlin_2_2_20].

• Upgrade: [Okio 3.16.0][okio_3_16_0].
