## Version 5.2.1

_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].
