Release Notes

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

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].
