 *  Fix: Don't re-encode `+` as `%20` in encoded URL query strings. OkHttp
    prefers `%20` when doing its own encoding, but will retain `+` when that is
    provided.
 *  Fix: Enforce that callers call `WebSocket.close()` on IO errors. Error
    handling in WebSockets is significantly improved.

Here’s what has changed since 5.0.0-alpha.17:

 *  Upgrade: [Okio 3.15.0][okio_3_15_0].
 *  Upgrade: [Kotlin 2.2.0][kotlin_2_2_0].
 *  Fix: Don't crash with a `NoSuchMethodError` when using OkHttp with the Sentry SDK.
 *  Fix: Retain the query data in the old `okhttp3.mockwebserver.RecordedRequest.path` property. We
    inadvertently changed this behavior when we introduced the `mockwebserver3` API.
